Abstract
To ensure reliable operation of the high voltage direct current（HVDC） projects,operational tests of thyristor valves must be carried out.As the operating frequency is subject to the power system frequency,how to test products at different frequency is a serious problem.Adopting the Xi＇an High Voltage Apparatus Research Institute（XIHARI） 50 Hz operational test circuit as a basis for meeting the requirements of operational test for valves in 60 Hz system,we studied and compared the current,voltage,other electrical parameters and the loss characteristics of the valves,and proposed an equivalent method and the equivalent parameters of operational test for valves in 60 Hz system by a 50 Hz test circuit.The results show that it is feasible to test a converter valve in different frequency synthetic operational test circuits,but appropriate equivalent is needed for different test items.The equivalent method provides a reference for research and test of the HVDC systems in different frequencies.关键词
