Abstract

An operation time sequence of two-way valve single injection test in synthetic global operating mode test device is as follows: setting 1,Vin to be negative, using negative synchronous voltage to trigger test piece positive valve; setting 2, Vin to be positive, using positive synchronous voltage to trigger auxiliary valve; dividing operation time sequence of each auxiliary valve and each test piece valve to be two stages of large current stage and high power source stage under single injection voltage-current synthetic test mode of two-way high voltage series thyristor valve.

Description

technical field [0001] The invention relates to a technology for synthetic full working condition test of a thyristor valve in a power system and a power electronic system, in particular to a control method for a two-way valve single injection test of a synthetic full working condition test device. Background technique [0002] With the gradual promotion of the application of power electronics technology in power systems, high-voltage valves based on thyristor series voltage equalization technology have become the core components of various high-power power electronic devices. For example, static var supplementary device (SVC), thyristor controlled series compensator (TCSC), high voltage direct current transmission technology (HVDC), etc. The operation test is an important test method related to improving the design and manufacturing level of various high-voltage series thyristor valves and improving their reliability. At present, the synthesis test method is generally used...
