Upgrade Study of High Power Electronics Laboratory for ±800kV UHVDC Valves

Abstract

The paper mainly described the upgrade study of High Power Electronics Laboratory (HPEL) in China Electric Power Research Institute (CEPRI), which will meet all the test requirements of plusmn 800 kV UHVDC valves. Based on the valves electrical parameters of plusmn 800 kV UHVDC demonstration project in China, the paper studied the UHVDC valve type test technology, gave the valve test parameters, the main equipments topologies, rated parameters and the basic waveshapes of the UHVDC valve insulation and operational tests.
