| Abstract: | Aiming at the problem of high -voltage auxiliary power supply switching in 660 MWpower plant,adopts the micro-controlled auxiliary power supply fast switching device,according tothe unit different operation mode,puts forward the switching scheme of auxiliary power supply fastswitching device,realizes fast switching and selective switching of two units. The application resultshows that this scheme can guarantee safe and stable operation for the high-voltage auxiliary powersupply system of units,it be suitable for the high reliability power supply and the two way powersource fast switching. |
