The research content of this article is the monitoring system of converter valve control equipment, including: a first valve base monitoring unit, which is connected to the first valve base control unit through communication and used to monitor the operating status of the first valve base control unit. The second valve based monitoring unit is communicated and connected with the second valve based control unit to monitor the operating status of the second valve based control unit. Monitoring control unit, including: at least one processor and a memory connected to at least one processor in communication, storing instructions that can be executed by at least one processor to achieve the following methods when at least one processor executes: determining the working valve based control unit based on the operating status of the first valve based control unit or the second valve based control unit. We need to determine whether the converter station has malfunctioned and stopped based on the valve based control unit in operation; When the converter station v experiences a malfunction and shuts down, determining whether the converter station has been put back into operation; When the converter station is put back into operation, the control unit for the control work is reset.
