| Abstract: | After more than 10 years of operation,the generator-transformer protection of the 300 MW thermoelectric units became technologically behind,aging,too complicated in checking,and less sensitive.To improve the action reliability of the protection,a retrofit was performed to replace the former protection with the microprocessor-based protection after comprehensive consideration of the protection configuration and the retrofit plan.Tests show that after the retrofit the performance of the new protection is far better than the former rectifier protection and the electromagnetic protection. |
