| Abstract: | Aiming at an accident of generator-transformer unit outlet circuit breaker trip withoutany protection device act in 330 MW coal-fired power plant,using gradual elimination method andfield simulation test,finds out the causes of the trip,puts forward effective solution and preventivemeasures. The application result shows that the improved measures eliminate the hidden safetytrouble,guarantee long periodic safe operation of the 330 MW coal-fired power generation unit. |
