众所周知，校正切换（包括输电线路和母线切换）可以改变电力系统的状态，从而影响电力系统的潮流分布、传输损耗、短路电流、电压分布以及暂态稳定性。本文基于有限迭代次数的快速解耦潮流（FDPF），提出了一种新的求解线路和母线最佳切换动作的算法，以缓解系统故障引起的过负荷和电压违规。提出了一种通用的母线倒闸动作模型，使新算法能够模拟任何复杂的母线倒闸动作。在39节点新英格兰系统上的仿真结果表明，本文提出的新算法能有效地解决过载和电压违规问题，且计算时间也令人满意。
It is widely known that corrective switching (including transmission line and bus-bar switching) may change the states of the power systems, and consequently, affect the distribution of power flows, transmission losses, short circuit currents, voltage profiles as well as the transient stability of power systems. In this paper, based on the fast decoupled power flow (FDPF) with limited iteration count, a new algorithm is developed to find the best line and bus-bar switching action for relieving overloads and voltage violations caused by system faults. A general model of bus-bar switching action is proposed such that the new algorithm can simulate any kind of complicated bus-bar switching action. Simulation results on the 39-bus New England system show that the new algorithm proposed in this paper can effectively solve the overload and voltage violation problems and the computation time is also satisfactory.
