| 摘 要： | 统一潮流控制器(UPFC)是一种高度可控的灵活交流输电装置。针对适用于高压大容量输电领域的双回基于模块化多电平换流器(MMC)的UPFC(简称MMC-UPFC),考虑其备用结构和运行保护原则,并将站外交流系统转化为MMC-UPFC子系统,以传统九状态UPFC可靠性模型为基础,建立改进的双回MMCUPFC七状态可靠性模型。建立MMC-UPFC的节点注入功率模型,并基于该模型将含UPFC的最优负荷削减模型应用到合肥南部电网实例中,验证了MMC-UPFC各运行状态对系统可靠性的改善能力,并进一步研究了MMC-UPFC安装位置对可靠性改善能力的影响。

| Abstract: | The unified power flow controller(UPFC)is a highly controllable flexible AC transmission(FACTS)device.It is necessary to consider the principle of operation protection and reserve structure of double-circuit MMCUPFC,which is suitable for high-voltage and large-capacity transmission field.And the seven state reliability model of MMC-UPFC based on traditional nine state UPFC reliability model was established by transforming the external communication system of the station into MMC-UPFC subsystem.Basing on the power injection model,the optimal load shedding model with UPFC was applied to the southern Hefei power grid.The ability of the MMC-UPFC's running state to improve the system reliability was verified,and the influence of the MMC-UPFC installation position on the reliability improvement ability was further studied. |
