Abstract :
The world´s-first power converter-fed variable speed pumped storage power system (VSPS) was commissioned in 1990. The VSPS has been monitored to verify the operating characteristics when a fault occurs in the electric power system. A one-line fault occurred in the transmission line in 1992. The over voltage protection system operated normally and the VSPS continued as normal. The authors simulated the fault with the EMTP and obtained a satisfying simulation result which was almost the same as the practical record.<>
