摘　　要：随着电网建设的发展,电网的元件数量与日俱增,结构也日益复杂,这对电力系统的安全运行与控制是一种挑战。大电网之间的相互联系使得供电可靠性在得到一定保障的同时也会出现将局部故障迅速传播到区域电网甚至是全国电网从而引发连锁故障的情况。研究了并联储能型FACTS元件在连锁故障发生时所能起到的作用,在电力系统分析综合程序中采用节点注入电流法建立其暂态的用户自定义模型。仿真结果表明并联储能型FACTS元件能够起到在一定程度上减少切机切负荷等控制量,抑制连锁故障持续发生的作用。With the development of power grid construction, there are more elements and more complex grid structures in the power system, which is a challenge to its safe operation and control. The link between bulk grids can make power supply reliability be guaranteed, but at the same time the local fault can be quickly spread to the regional and even national networks to trigger a cascading failure. This paper studies the effect of parallel FACTS element with energy storage to cascading failures when fault occurs, and node injection current method is adopted to establish its transient user-defined model by using power system analysis software package. Simulation results show that parallel FACTS element with energy storage can reduce the number of control measures like generator-shedding or load-shedding to a certain extent, and inhibit the progress of cascading failures.
