| Abstract: | According to the summary of Operation and commissioning of microcomputer protection for large generator - transformer bank and auxiliary transformer in phase 2 of Qinshan, the existent problems of the microcomputer protection were analyzed, including self- holding of outlet of generator -transformer bank, diflerential protection of main transformer, differential protection of 500 kV side, suppression device of secondary harmonics. Analysis on the causes of miss operation and its corresponding countermeasures are put forward, and the suggestions to improve the method of frequency measurement, record wave file and alarm lamp are presented. |
