| Abstract: | The configuration program and setting calculation of the 100% stator ground fault protection based on the NARI PCS-985B equipment are introduced by taking the reform project of generator-transformer-unit protection as an example, and the field testing data validates the correctness of setting calculation. Besides this, the problem of mismatching between the zero-sequence voltage interface of PCS-985B equipment and field device is discussed, and reasonable solution to the problem is provided. |
