Problems solved by technology

[0003] The problem with this architecture is that two sets of redundant VBE systems share one light receiving board. Since the operation of the converter valve requires real-time monitoring of whether the return inspection signal of the valve is normal, when the light receiving board fails, the return inspection signal cannot be received. , the converter valve will be forced to shut down

Abstract

The invention relates to a converter valve checkback framework for realizing online replacement of VBE light receiving boards, including a thyristor electronic board connected to the converter valve signal, including a VBE main system and a VBE backup system, and the VBE main system is provided with a first The light receiving board, the VBE standby system is provided with a second light receiving board, both the first light receiving board and the second light receiving board are connected with an optical splitter, and the optical splitter is connected with the thyristor electronic board. By adopting the above technical solution, the risk of forced outage of the direct current transmission system is reduced, and the reliability of the operation of the converter valve is improved; at the same time, the online replacement of the light receiving board is realized when the light receiving board fails.

Description

technical field [0001] The invention relates to the technical field of thyristors of converter valves in electric power systems, in particular to a converter valve checkback framework for realizing online replacement of VBE light receiving boards. Background technique [0002] In the current (Ultra) HVDC system power transmission system, the thyristor electronic board sends the return inspection signal to the light receiving board of Valve Base Electronic (Valve Base Electronic, hereinafter referred to as VBE) through optical fiber, and the light receiving board sends the return inspection signal sent to the VBE system. [0003] The problem with this architecture is that two sets of redundant VBE systems share one light receiving board. Since the operation of the converter valve requires real-time monitoring of whether the return inspection signal of the valve is normal, when the light receiving board fails, the return inspection signal cannot be received. , the converter v...
