种适用于分布式电源管理的新型智能开关

分布式电源改变了配电网的运行模式,对配电网的运行管理提出了新的挑战和要求。针对这种情况,运用一、二次融合的设计理念,提出了一种适用于分布式电源管理的新型智能开关设计,应用结果表明:该智能开关采用电子式互感器采集全部运行数据,具备三段式过流方向保护、零序方向保护、电能量计量等功能,可以很好地解决分布式电源管理及多电源线路的故障判断与故障隔离等问题。

A new type of intelligent switch adapting for distributed generation management

Distributed generation changes the operation mode of distribution network and makes newchallenge and demand for operation and management of distribution network. Under this situation,applying the syncretic design idea of primary and secondary power equipment, puts forward a new typeof intelligent switch adapting for distributed generation management. The application result shows thatthe intelligent switch of adopting electronic transformer to collect all of the operation data has thefunctions of three-section over current directional protection, zero sequence directional protection andelectric energy measuring, etc., it can solve the problems of distributed generation management, judgeand separate the fault of multiple transmission power lines.
