| Abstract: | On January 4, 2005, the pump condition trip-out of two generating units of Shahe Pumped-storage Power Station occurred due to the earthing failure of the phase-C of system. According to the wave recording data from the failure wave-recording device of 220 kV, we found out its protection eanse and analyzed its correction of protection act. The results showed that such protection is a low power protection and its protection act is correct, which can be used for referenee in the analysis of act eanses of protection devices for other pumped-storage power plants. |
