| Abstract: | This briefs the operation experience of WFBZ-01 type microcomputer-based protection used on 300 MW generator-transformer unit in Wangtin Power Plant. Based on the operation experience, some suggestions on large-sized generator rotor single point-ground fault protection ,rotor two points-ground fault protection, interturn fault protection, loss-of-field protection, lower impedance protection and main protection etc are put forward. |
