| 摘 要： | 500 kV统一潮流控制器作为一种新型的动态电力电子设备可用于控制受入通道的有功潮流,合理分配受端电网受入的电力;同时,统一潮流控制器又可同时作为动态无功设备为系统提供无功支撑。文章对含500 kV统一潮流控制器的大容量直流馈入系统展开电磁暂态分析,对交直流系统、统一潮流控制器以及相关控制系统进行详细PSCAD建模,并根据统一潮流控制器并联侧的动态特性设定无功响应策略。结果表明,统一潮流控制器可提升大容量直流馈入系统的电压稳定性,同时可缓解近区直流换相失败的情况。

| Abstract: | As a dynamic power electronic device, 500kV unified power flow controller (UPFC) is applied to control the power flow of transmission lines and optimize the distribution of feeding power into receiving-end grid. Meantime, UPFC is able to provide system with instant reactive power support. In this paper, effect of 500kV UPFC on HVDC feeding power grid is conducted through electromagnetic transient simulation. AC/DC system, UPFC device and control system including reactive power response strategy are built detailed in PSCAD, which is according to the dynamic characteristic of UPFC shunt side. Results show that UPFC can improve the voltage stability of HVDC feeding system and relieve nearby DC commutation failure. |
