摘要

统一潮流控制器可以优化电网潮流分布，提高系统输电能力。实际应用时，UPFC 接入后系统的可靠性水平变化是 UPFC 接入方案需要考虑的重要因素。针对安徽电网随着网架规模的不断扩大而出现的潮流分布不平衡问题，提出双回 UPFC 结构在安徽电网的应用方案，并论证其必要性; 然后，建立双回 UPFC 元件的可靠性模型，基于蒙特卡洛模拟和最优负荷削减，编写含双回 UPFC 的电力系统进行可靠性评估算法; 最后，基于电网实际数据，分析 UPFC 接入后对系统可靠性的影响，并验证 UPFC 应用方案对电网可靠性的改善能力。

Abstract

The unified power flow controller (UPFC) can optimize power flow distribution of power grid and improve transmission capacity of the system． In actual application，the change of system reliability index after UPFC is accessed is an important factor to be considered in UPFC access solution． Aiming at the unbalanced distribution of power flow in Anhui power grid with the continuous expansion of grid scale，the application scheme of double － circuit UPFC structure in Anhui power grid is proposed and its necessity is demonstrated． Then，the reliability model of double － circuit UPFC elements is established． Based on Monte Carlo simulation and optimal load reduction，the reliability evaluation algorithm of power grid with double － circuit UPFC is written． Finally，based on the actual data of power grid，the influence of UPFC access on system reliability is analyzed，and the ability of UPFC application scheme to improve power grid reliability is verified．
