Key Technologies and Engineering Application of Converter Valve MonitoringSystem for Flexible HVDC

In order to monitor the operation status of the converter valve and the valve basic controller in the flexible HVDC transmission project and improve the operation safety of the converter valve,the role of flexible DC converter valve monitoring system is becoming more and more important.Based on the actual project requirements,and considering different application scenarios such as field subsystem debugging,converter valve maintenance,and normal operation and maintenance,a flexible HVDC converter valve monitoring system with dual network and dual redundancy architecture is developed,which uses the technology of automatic page layout and parameter matching for optimization,and the data caching mechanism of"memory+file"for massive data processing.The system has the functions of processing massive data with high-speed,displaying and storing telecommunicating and telemetry messages,recording high-frequency sampling fault and processing waveform.It can record information in real time with microsecond precision,and has the functions of remote control,modifying the status and key parameters of converter valve and valve control equipment at the same time.The system has been successfully applied in Zhangbei renewable energy flexible HVDC power grid demonstration project,and its performance meets the demand of monitoring and control of the converter valve and the valve basic controller.
