The invention relates to a device and method for detecting a valve control system for a converter valve. The device comprises a logic processing circuit, and a VBE state selection switch circuit and a single valve selection switch circuit which are connected with the logic processing circuit, wherein the logic processing circuit is connected with the valve control system; the logic processing circuit performs processing according to the on-off state of the VBE state selection switch circuit to obtain a VBE state signal, performs processing according to the on-off state of the single valve selection switch circuit to obtain an FCS signal, and outputs the VBE state signal and the FCS signal to the valve control system, wherein the VBE state signal is used for switching the valve control state of the valve control system, and the FCS signal is used for controlling the valve control system to output a trigger signal to the converter valve, so that a trigger function test of a thyristor level in the converter valve by the valve control system is completed, the test efficiency of the thyristor level and the valve control system is greatly improved, the test time is shortened, and the test range is expanded, and the operation reliability of the core equipment of a converter station is ensured.
Description
technical field [0001] The present application relates to the field of electric power technology, in particular to a valve control system detection device and method for a converter valve. Background technique [0002] With the rapid development of my country's electric power technology, a number of UHV DC transmission projects that have been completed have greatly improved the efficiency of cross-regional long-distance power transmission and power consumption. In this type of UHVDC transmission system, the rectification and inversion processes are combined in one converter station, which is completed by changing the trigger angle of the core equipment HVDC converter valve, and the trigger angle of the converter valve is controlled by the valve control system. (Valve Base Electronics, VBE) valve control state switching and output trigger signal to control. As the control center of the converter valve operation, the valve control system is responsible for triggering the conv...
