Description

Technical Field

It is a network composed of overhead lines, cables, poles, towers, distribution transformers, disconnectors, reactive power compensators and some ancillary facilities. It plays an important role in distributing electric energy in the power grid. The distribution network generally adopts a closed-loop design and open-loop operation, and its structure is radial. The closed-loop structure is adopted to improve the flexibility of operation and the reliability of power supply; the open-loop operation is to limit the short-circuit fault current on the one hand, to prevent the circuit breaker from exceeding the interruption capacity and exploding, and on the other hand to control the scope of the fault and avoid the expansion of the scope of the fault power outage; classified by voltage level: high-voltage distribution network, low-voltage distribution network, classified by power supply area: urban distribution network, rural distribution network, factory distribution network, classified by power grid function: main network, distribution network, power supply reliability is one of the important indicators to measure the performance of the distribution network, which includes the power supply stability, failure rate, repair time and other aspects of the line.
