继电保护交流电压切换原理改进的几种建议

Several Recommendations on Improving Relay Protection AC Voltage Switching Principle

在湖南省电力系统双母线接线方式中,因为设计原理的原因会发生因直流失压导致交流小母线失压的情况,为此简单介绍此种电压互感器二次切换原理。

In the double generatrix connetion of Hunan power system,the design would lead to AC generatrix lose voltage.In this paper,several principles and advices are introduced.
