Guangxi green building design code is a guiding document for green buildings in Guangxi, which represents the highest level of green buildings in Guangxi province and plays a role in standardizing and guiding the design of green buildings in Guangxi. Among them, what are the provisions of Guangxi green building design code for power supply and distribution system design? The following is the introduction of the provisions of Guangxi green building design code for power supply and distribution system design brought by the construction network for reference.

the design of power supply and distribution system should reasonably determine the load level and capacity. The operation energy consumption of the system should be analyzed and the corresponding energy-saving measures should be taken. For the system with large load change, the corresponding energy-saving operation mode should be adopted according to different working conditions.

The power distribution room and floor distribution room of the power supply and distribution system should be located in the load center as far as possible, and the power supply radius of the system should be controlled reasonably to improve the system efficiency and reduce the line loss.

for the power supply and distribution system with unbalanced three-phase or single-phase distribution, it is appropriate to adopt automatic split-phase capacitor compensation or automatic split-phase reactive power compensation device.

the power supply system should be monitored for harmonics.

when the harmonics of the power supply and distribution system or equipment exceed the harmonic limit specified in the relevant national or local standards, measures should be taken to suppress and control the harmonics of the main electrical and electronic equipment in the building or the lines where they are located, and the following requirements should be met:

1) when the harmonics of the system or equipment exceed the harmonic limit specified, it is appropriate to analyze the nature of the harmonic source and the measured parameters of the harmonics, and take targeted measures to suppress and control the harmonics.

2) in the power supply and distribution system, it is advisable to set up filtering devices at places with large harmonic interference and reactive power compensation.

the cross-section size of power cables with a capacity of 11kV and below should be selected in combination with technical conditions and economic current.
