Line Loss

distribution network line usually adopt neutral point grounding way of three-phase three-wire power supply, improve the power supply reliability, reduce the line loss, increase the margin level of the distribution line, reduce the rate of tripping. But using three-phase three-wire power supply line in the actual operation of distribution network, the single-phase earth fault happens often, seriously affected the substation equipment and the safe and economic operation of the distribution network. Based on such fault is analyzed, and puts forward new on feeder terminal for such fault detection scheme.

Distributed Power

In distribution networks with distributed power supplies, distributed power supplies can also be used as backup power sources to support the grid. If a distribution network contains multiple distributed power sources, the distribution network becomes a complex power grid with multiple power supplies. When a short-circuit fault occurs at a certain point on the power distribution network, the size, direction and duration of the short-circuit current are no longer single due to the existence of distributed power, and will vary with the location and capacity of the distributed power supply system. The change, in turn, affects the current in the grid, resulting in the generation and propagation of additional current. This power grid of power electronics will cause problems such as excessive standard mis-operation, abnormal heating of the converter and component burnout, and communication system failure. It is of great and practical significance to study the influence of distributed power in distributed power distribution networks.
