摘要
结合500kV官山变电站的实际需求,设计了直流融冰兼SVC装置技术方案;介绍了直流融冰兼SVC装置的基本结构、原理、功能和运行方式,并通过电力系统电磁暂态仿真软件PSCAD/EMTDC对技术方案中的部分线路进行仿真;仿真结果表明,本方案的直流融冰兼SVC装置有效地解决了长距离超高压线路的覆冰问题,并且提高了电网电压的支撑能力。
In this paper, technical scheme of DC de-icing and SVC （static var compensator） is designed with combination of the actual requirement of 500 kV Guanshan substation; the basic structure, principle, function and operation mode of the DC de-icing and SVC device is introduced; and part of line in the technical scheme is simulated through the electromagnetic transient simulation software PSCAD/EMTDC of power system. It is shown by the simulation result that the ice-coating problem of long distance HV line is solved effectively and also the support ability of the power voltage is impxoved by the DC de-icing and SVC device.
