基于稳控装置平台的电网双向备用电源自投功能的实现

摘要

利用稳定控制装置平台的强大功能,实现两台主变之间备投和电源进线之间的备投功能,还可以利用两个站间电源联络线和装置的通信接口,向对侧装置发送远方命令,实现两个变电站之间互为双向备投功能,提高了变电站供电的可靠性.自投成功后,如备用电源线路过载,还可以运用稳定控制的方法,联切部分负荷,保证电网安全稳定运行.%It has realized the function of backup power supply switching between two main transformers and between two power supply lines by using powerful function of stability control device platform. It can use power supply line between two substations and stability control device's multi-communication interfaces to realize double direction backup power supply switching function through sending remote close instruction to another stability control device. It enhances the reliability of power supply of substation. After the success of backup power supply switching,if backup power supply line is overload, it can use the method of stability control to ensure power system safety stability operation by load-shedding.
