摘要:

针对近年国内特高压直流输电工程中换流阀控制设备的实际运行工况,设计了一套完整的特高压直流输电工程阀控动模试验系统,整个试验系统包括整流侧换流阀、整流侧阀控(valve control equipment,VCE)、逆变侧换流阀、逆变侧VCE、控制与监视后台系统。该试验系统直接采用工程用晶闸管来搭建微型换流阀,相比实际工程用换流阀,减少了每个单阀的晶闸管数量,其他换流阀设计参数与实际工程相同,相较于采用实时数字仿真(real-time digital simulator, RTDS)系统模拟换流阀参数的方式,更有利于换流阀及输电线路参数的精确获取与处理,对阀控功能的验证更加有效。最后对许继集团研制的VCE800阀控系统进行了试验,验证结果表明该阀控动模试验系统可以满足特高压直流工程阀控设备联调需要。

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.
