Abstract

Abstract:

According to the actual operating condition of the converter valve and valve control system in UHVDC transmission project in recent years, this paper designed a complete simulation test system for valve control equipment （VCE） in UHVDC transmission project, including converter valve and VCE of rectifier and inverter, and control and monitoring systems. The engineering-used thyristor was used to build miniature converter valve in this test system, so as to reduce the thyristor number of each valve compared with the converter valve used in practical engineering, while the design parameters of other converter valves was the same as that of practical engineering. Compared with the mode that used real-time digital simulator （RTDS） to simulate the parameters of converter valves, this system is more beneficial to the accurate acquisition and processing of the parameters of converter valve and transmission lines, and more effective for the verification of valve control function. Finally, the VCE800 valve control equipment made by XJ Group Corporation was tested. The result shows that the dynamic simulation test system of the VCE can meet the joint debugging test needs of VCE in UHVDC project.

Key words: UHVDC transmission, valve control equipment, control and monitoring systems, dynamic simulation test
