摘要
厂用工作电源和备用电源为不同电网时,电源间的相位角是随机变化的,其手动正常切换及事故切换都不能采用同一电网中的切换方式。通过分析厂用电母线电压衰减特点,并结合某电厂探索运用实例,总结出两电网的厂用电切换方式。
The phase angle between power sources is a random variable when the auxiliary power and pare power are from the different power grids. It can＇t adopt auxiliary power switch model of the same grid on operating manual or accident switch. This paper analyzes the residual voltage characteristics of busbar, and sums up auxiliary power switch model between two grids with the examples.
