1, high-speed railroad traction power supply system load characteristics and safety management of the characteristics of the analysis
1.1, high-speed railroad traction power supply system load characteristics
High-speed railroad traction power supply system load characteristics and the ordinary railroads there is a very obvious difference:
(1) Load Frequent fluctuations. The size of the load is related to the number of trains running on the power supply arm, the line gradient and the running speed of the trains. The load of high-speed rail traction substation will fluctuate with the number of trains in the two power supply arms and their load status at any time.
(2) Large traction load. High-speed train has the characteristics of fast speed, high density during peak hours, etc., and the air resistance will increase exponentially with the speed, at this time, the train traction needs to overcome the air resistance to run, which makes the traction load larger, and the current of a single car of high-speed train can be up to 600~1000A, while the current of the general-speed train is generally not more than 300A.
(3)High-speed train, in the process of high-speed operation, often need to overcome the air resistance traveling, if the train wants to maintain high speed, it must continue to get electricity from the contact network, which makes the train itself relatively high load ratio, and the time of receiving electricity is longer.
(4) High power factor. The power factor is above 0.95 with the use of alternating - direct - alternating trainsets.
1.2, safety management characteristics
The characteristics of high-speed rail traction power supply safety management are mainly reflected in the following four aspects:
(1) Dynamic. High-speed rail traction power supply load has very obvious mobility and uncertainty, and the load is often in an unbalanced state, which makes all kinds of safety problems occurring dynamic changes, once there is an accident or power supply interruption, it will inevitably cause huge economic losses and serious negative impact.
(2) Repeatability. Due to the traction power supply equipment are set in the open environment, the operation of the equipment by the temperature changes and climate conditions are relatively large, thus making the seasonal safety problems occur repeatedly.
(3) complexity. The contact network of the traction power supply system has a very obvious complexity, such as the complex environment, unpredictable climate, no spare equipment and so on.
(4) uniqueness. The impact load of high-speed rail traction power supply is very frequent, and the harmonic content is larger, at the same time, the pollution of the operating environment is also more serious, which puts forward high requirements for the safety management of traction power supply. For this reason, effective measures must be taken to improve the safety management level of traction power supply, which is of great practical significance to ensure the safe, stable and reliable operation of high-speed rail.
2, the main safety problems faced by the traction power supply system
At present, the main problems faced by the traction power supply system are: harmonic problems, negative sequence current problems, power factor problems, locomotive over-phase problems, grounding problems, relay protection problems, bow-network relationship problems, insulation with the problem of electromagnetic compatibility.
1) Harmonic currents injected into the power supply system will be detrimental to the reliability of the communication system, control system, and reduce the operating efficiency of the power equipment.
2) Negative sequence currents can reduce the utilization rate of the customer's power and cause the surface temperature of the rotor of the customer's rotating motor to rise too high.
3) overvoltage phenomenon occurs when the neutral section of the locomotive overcharge phase separation, overvoltage level can sometimes reach the value of the contact wire insulators to break through the arc may be burned contact with the hanging chord; locomotive recharged, there is an overcurrent phenomenon, the overcurrent level of the locomotive can reach the level of the normal operation of the current of the 5-7 times, overcurrent may be detrimental to the normal life of the equipment, the impact of relay protection actions The overcurrent may damage the normal life of the equipment and affect the correctness of the relay protection action.
4) The contact network system is a non-standby system, and the locomotive is connected to the contact network through the pantograph and sliding to obtain electricity. In the process of locomotive movement, there are different directions of vibration, these vibrations are transmitted to the contact network through the pantograph, the contact network vibration. Good bow network relationship is the contact network vibration characteristics and pantograph vibration characteristics of the same, between the two for a follower system, so that the contact network and pantograph to maintain good contact.
5) high-voltage equipment, the charged part of the equipment shell, the earth between the need for insulation, different voltage levels, different phases of high-voltage equipment also need insulation. Insulation with, that is, in a power supply system, due to the existence of a large number of insulated parts, through the insulation level of each part (resistance to frequency voltage, impact voltage capacity) of the choice, in order to meet the requirements of the insulation level of the system under the premise of achieving a reasonable level of technical and economic indicators. Insulation with the problem of electrified railroad research in recent years, one of the important topics, the reason why attention is drawn to, because in different environments, if you do not take into account the insulation with the problem, the application of grounding technology measures is difficult to achieve the desired results.
3, the main factors affecting the safety of the traction power supply system
The main factors affecting the safety and reliability of the traction power supply system can be divided into equipment factors, power supply quality factors, external influences, system operation factors, management factors, and other parts. In each part of the big factors, there are many small factors, this paper will mainly be various types of influence factors list as follows, see table 1:

Introduction to the railroad intermediate station safety management
Abstract With the reform and development of railroads, the level of railroad technology, equipment and equipment is increasingly improved, train speed increases, the density of trains increases, the quality of traction is increased, in the face of the new period of transportation organization changes to the safety management of the new situation, new changes, new problems. Situation, new changes, new problems, showing a failure to adapt to the current pace of reform and development to accelerate the pace of safety management is faced with many problems, how to solve the new period of railroad intermediate station safety management, starting from the new ideas of safety risk management, a useful discussion.
Keywords intermediate station; safety; risk; management
Safety is the eternal theme of railroad transportation, is the guarantee of reform and development, is the lifeline for the survival and development of enterprises, but also an important prerequisite for the railroad to do a good job of all work. Actively explore high-speed, heavy load, the new situation of railroad safety management is an important responsibility of each manager. Intermediate station as a railroad station under the jurisdiction of the most basic groups, is an important link in railroad transportation, in the security, stability, smooth flow has a very important role. Railroad part of the intermediate station are in a geographically remote place, away from the authorities, the environment is poor, inconvenient transportation, life is difficult, a number of difficult factors superimposed on the management of the intermediate station has brought great difficulty, therefore, to improve the intermediate station safety management is our current focus on the study of the subject.
1. Problems in the management of intermediate stations
1.1 The lack of high standards of safety.
A high standard is the prerequisite and basis for good work, both target requirements, but also quality requirements; both source requirements, but also the results of the requirements. The reason why some intermediate stations failed to achieve safety goals, and even lost the war on safety, the key is not high standards, satisfied with passing, not seeking to pass, so that the station's safety work hovering at a low level, many problems develop into persistent problems, the same kind of accidents occur repeatedly. Specifically manifested in: First, the standard understanding of ambiguity. Although we have repeatedly emphasized the issue of standards in the past few years, but until now, some cadres and workers on the operating standards, technical standards, equipment standards ambiguous, high standard positioning has become a kind of mantra. Second, the implementation of standards is not thorough enough. After many years of the whole chapter of the system, from the road bureau to the station section has formed a set of safety management system standards, in ensuring transportation safety has played an important role. However, in the daily work of some intermediate stations lack of implementation of the system standard of seriousness, conscientiousness, persistence, not according to the standard, the result triggered an accident.
1.2 personnel quality does not adapt
In recent years, with the railroad system reform continues to promote, new technologies, new equipment gradually put into use, coupled with the training and education mechanism to keep up with, resulting in the overall quality of the staff has been more and more unable to adapt to the requirements of the new situation of safe transportation production. First, some station managers have been unable to keep up with the pace of new management, new management knowledge is poor, new technical knowledge is not deep, can not better guide the station's operation of the positions, resulting in the station's key operations can not control. Secondly, some workers have not firmly established the principle of "safety first". Safety first? Ideas, safety awareness is weak, not strong sense of responsibility, the operation behavior is not standardized; technical and business level is poor, especially the mastery of the new technical knowledge is less, the abnormal situation of the operation of the emergency response capability is not strong, habitual operation is more common, simplify the operation procedure language, illegal operation habitually, to the safety of the production of a certain security risks.
1.3 safety management is not adapted
For a long time, by the influence of traditional management, safety management is still stuck in the inherent management mode, management is often still rough, static, passive, did not do to keep pace with the times, safety risk management is still basically shallow, management methods are still relatively simple, lack of foresight, the management of ideas have not been clarified. Mainly manifested in: ① management concept backward, active management lagging behind, can not be strict control, there are some station managers exist? No accident is safe? the one-sided understanding, diluted prevention-oriented, eliminate the idea of hidden danger; ② part of the station manager lack of entrepreneurial spirit, good people and formalism, serious, floating style, accountability is not strong, the workers work against the rules, simplify the operating procedures turn a blind eye, so that the workers in the operation of the habit of becoming a standard culture; ③ station manager a day's work to play a bad job, the station's pre-shift roll-call and the handover will be grasped with low quality, and even some simplify the handover will be poor, and even the quality of the handover will be poor. Even some simplify the handover meeting, in-depth inspection of the operation of each post did not seize the main problem, more superficial phenomena; ④ do not pay attention to the technical and business training and learning, to cope with more, less to solve practical problems, basically a formality; ⑤ security risks of the implementation of the poor implementation of the precautionary approach to the key operational procedures to control the lack of power.
1.4 Poor control of safety risk management
Some station managers have unclear ideas and vague understanding of safety risk management, lack of scientific management tools, and only pay attention to the results, not the process. First, the key operations of the station, especially for special periods and phases of the key work can not be timely investigation, but also the lack of the ability to judge ahead of time, the investigation of the risk of the source of targeted control measures are not rigorous, not detailed, lack of operability. Secondly, the key parts and links of the operation of the control is not effective, can not seriously implement the rules and regulations and operating standards, can not focus on, such as construction operations organization, abnormal conditions to send and receive trains, shunting operations, stay car anti-skidding and send and receive special requirements of the train can not be strictly in accordance with the provisions of the key operating procedures for the control of the recurring inertia, corrective action, tracking and implementation of the poor, posing a serious threat to the safety of production. The company's website has been updated with the latest information on the company's website.
2. Improve the station safety management control ability of a few suggestions
Station safety management, mainly refers to the station in the various production processes, through the adoption of a variety of safety measures, strict implementation of rules and regulations and operating standards, comply with labor discipline and operating discipline, strengthen the process of operational control, eliminate unsafe factors, so as to prevent the occurrence of personal injury and death and a series of driving accidents. Implementation and supervision means.
2.1 Improve the quality of personnel, lay a firm foundation for safety
Production safety is a complex systematic project, to do a good job of this systematic project must lay a solid foundation, this foundation is the quality of personnel. Only the quality of personnel continue to improve, in order to constantly adapt to the requirements of the development of the railroad, safety production is a reliable guarantee.
2.1.1 intermediate station stationmaster is not only the intermediate station safety management organizer, but also the safety production activities of the conductor and ordinary participants. Intermediate station safety work is often, a large number of detailed, these jobs are inseparable from the station manager, at the same time, the station manager must also personally participate in and monitor the special circumstances of the key operating procedures, the intermediate station manager's own quality of how to the entire station safety production management has a pivotal impact. For this reason, it is crucial to improve the comprehensive quality of the intermediate station manager. The car station section should strengthen the training management of the intermediate station manager, pay attention to the training of the reserve station manager, to provide them with a platform to enhance, if necessary, the introduction of a competitive mechanism, selected competent qualified intermediate station manager; at the same time can be organized by the station manager to go out, please come in, mutual exchange of learning and broadening of ideas, to learn from each other, and to improve their management level and technical and business level.
2.1.2 With the continuous improvement of the level of technical equipment and equipment, the changes in the organization of the line, the main types of work on the line of the technical quality of the staff is also demanding more and more high, do not adapt to the new situation of the railroad safety and transportation production requirements have been gradually revealed. Therefore, we should vigorously carry out technical and business training work to create a strong learning atmosphere. For the new technology, new equipment and new requirements, the organization of a variety of training activities, focusing on the effectiveness of the selection of good technical and business experts and sharp, to achieve the purpose of the overall improvement of the point to lead the face. Through the improvement of the comprehensive quality of the staff, we can really achieve standardized management of the team, excellent staff performance, and orderly safety, so as to make the safety production step into the benign cycle of the track of development. 2.2 Strengthen the basic construction, strengthen the group management
Grasp enterprise management, first of all, must start from the foundation, grasp the foundation must also start from the group, so the group management is the starting point and landing point of safety management. First, according to the management requirements of the intermediate station, and combined with the actual situation of the station, to further improve, supplement, develop various management methods, regulations and assessment system, focusing on strengthening the "station details" of the revision and improvement of the work, and gradually establish the "station details" as the main body of a variety of operational methods and measures for the extension of the rules and regulations of the system to achieve a standardized and reasonable, focused, targeted and operable, to provide safe production of the system guarantee. System guarantee. Secondly, the driving team leader is not only the driving commander, but also the driving organizer, so it should be selected as the team leader with strong sense of responsibility, skillful technology, leading by example, daring to grasp and manage, and playing the role of organizing and leading in the work, so that the overall technical and business skills of the team and the ability of the team leader's driving organization and command can be further improved. Thirdly, we insist on carrying out the activities of pre-emptive thinking, mutual control in the class and analysis and summarization after the class, so as to achieve targeted prevention in advance, mutual control of key operational procedures in the operation and rolling improvement after the class. Fourth, implement job operation standards, improve the level of standardized operation, and strengthen the self-control, mutual control and joint control system. Fifth, the construction of self-control team as a hand, strengthen the work of the whole chapter, further standardize the management of the team, the implementation of the implementation of self-control team, to cultivate a quality, consciously comply with the rules and discipline of the army, to ensure safe production to lay a solid foundation. Sixth, the establishment of incentives for safe production, the implementation of security joint economic responsibility system, the implementation of personal security team, team security station, station security station (section) of the guarantee responsibility system, the implementation of the layers of security, layers of responsibility, responsibility for performance, reward and punishment, award and punishment, and fully mobilized the enthusiasm of the whole staff safety production.
2.3 Strengthen safety management, strengthen the operation process control
2.3.1 Pay close attention to the process control, to ensure that the safety management of all aspects of the comprehensive control
The so-called operation process control refers to the whole process of the operation, all the relevant personnel to participate in the operation of the process of self-control, clear control of the project, the content of the method and the relevant responsibility of the personnel to realize the operation of the job control and procedure control, make the whole process of the operation of the control and control of the operation. Procedure control, so that every aspect of the whole process of operations are placed under control, and thus ensure the process of operational safety and quality, so the strict standardization of operations is also the control of operational procedures.
Process control should be based on? Prevention-oriented, grasp the small enlargement, prevention, prevention, prevention? The concept of results for the heavy process, change the treatment for prevention. Strictly implement the concept of "self-control, mutual control, joint control". Self-control, mutual control, joint control, monitoring? System, adhere to the self-control as the core, to mutual control, joint control as the focus, monitoring as the key to the implementation of security, full, all-round, the whole process of dynamic control is the control center of security management, but also a strong guarantee of security control.
2.3.2 Strengthen safety risk management, strengthen the key link control
In the production process of railroad transportation, a link out of control may lead to the occurrence of traffic accidents, that is to say, control and loss of control with the same, safety and accidents co-exist. So we have to grasp the intrinsic connection between safety and accidents, systematic analysis, investigation and judgment. To combine the reality of their own safety production, according to the unit's production organization, equipment and facilities, personnel quality characteristics, personal safety and other risks as the focus of the management risk that may lead to accidents, operational risk, equipment risk as the key to a comprehensive investigation and judgment, an all-round identification of sources of risk and risk points, focusing on effective prevention and control. First, strengthen the control of key operations. Station operations in the process of weak parts, weak links should be strengthened safety control. Such as the organization of construction work, unusual circumstances to send and receive trains, shunting operations, stay car anti-skidding and send and receive special requirements of the train and so on need to focus on our card control. Secondly, we should strengthen the security risks of the advance prevention, focusing on the prevention and control of the incipient, tendency and regularity of the problem, at the same time, we should rectify and implement the inertia and tendency of the problem, and try our best to solve the difficult and critical problems.
2.3.3 Establish the concept of safety management, to ensure that the safety of sustained, stable and healthy development
The safety of production is gained from the strict, but lost in the wide. Strict and effective management is a prerequisite to ensure safe production. Safety management is a systematic project, involving all aspects, to distinguish between primary and secondary, to seize the main contradictions, to dare to manage, good management. Penetrate the concept of scientific management into daily work, continue to deepen safety risk management, according to ? The problem is in the field, the reason is in the management? The idea, vigorously strengthen the foundation of management, to solve key and difficult problems, to promote the strict implementation of the safety work, to ensure that the safety of orderly and controllable.
3. Conclusion
Under the new situation of continuous reform and development of the railroad, it is crucial to grasp the safety management of the intermediate station. In the face of many practical difficulties in the intermediate station, should further clarify the management of ideas to vigorously promote safety risk management as a breakthrough, strengthen risk identification, research and control. In order to strengthen the safety source management, strengthen the field operation control, strict safety inspection and supervision as a means to take targeted control measures to ensure the healthy development of the intermediate station transportation safety production.
