    摘要:

    为量化评估统一潮流控制器(unified power flow controller,UPFC)装置对电网运行可靠性的影响,以200 kV南京西环网UPFC工程为研究对象,分析了含UPFC系统可靠性评估的方法和流程。首先基于UPFC子系统划分,建立了UPFC各子系统无备用元件和有备用元件情况下的可靠性模型,在此基础上获得UPFC系统两状态模型,由此提高了传统电力系统可靠性评估方法在含UPFC系统的适用性。最后,结合南京西环网实例,重点分析了装设UPFC、新建线路、采用倍容导线等不同方案以及UPFC不同安装位置对电网可靠性的影响,分析结果可为后续柔性输电装置在江苏应用提供借鉴。

    Abstract:

    In order to quantitatively evaluate the influence of UPFC device on the operation reliability of power grid,this paper takes UPFC project of 200 kV Nanjing West Ring Network as the example,and the method and process of the reliability evaluation of the system with UPFC is analyzed.First,based on UPFC subsystem division,the reliability model of each subsystem with no spare components and spare components is established.Based on this,the two-state model of UPFC system is obtained.Finally,combined with the case of Nanjing West Ring Network,it was mainly analyzed the influence of different schemes such as UPFC,new line and double capacity wires and different installation locations of UPFC on the reliability of power grid.
