摘要

现有电网恢复研究中将快速切回(FCB)机组加入电网串行恢复序列，未充分利用FCB机组能够独立恢复周边电源和负荷的能力。与传统的黑启动水电机组相比，火电机组的FCB功能不能100%成功实施，含FCB机组的电网恢复需要根据黑启动电源情况动态分区。因此，文中在传统GN分裂算法的基础上，提出了适用于含FCB机组电网的分区恢复策略。首先，采用网络的Laplace矩阵特征值识别分区数量，同时考虑了电网分区中黑启动电源要求、功率平衡要求，以及分区划分的速度要求，建立基于改进GN分裂算法的电网分区方法，实现含FCB机组电网的快速自动分区。最后，新英格兰系统和部分江苏电网实际系统仿真结果表明，所提分区方法能够有效地对电网进行动态分区。

Abstract

The current restoration strategy for power systems with fast cut back(FCB)units is to restore units in sequence

in which the FCB units' ability of restoring surrounding power sources and loads has not been fully utilized. Compared with conventional hydropower units

the FCB function of thermal units cannot be implemented for all units. It is necessary to dynamically partition the power system with FCB units according to the number of energized units. Therefore

this paper proposes a dynamic partition strategy for the restoration of the power system with FCB units based on the conventional Girvan Newman(GN)algorithm. Firstly

by using Laplacian matrix eigenvalues of power network to identify the number of subsystems

an improved Girvan Newman(GN)algorithm is built to divide the blackout system. Meanwhile

the dividing speed and the balance between black-start units and loads in a subsystem are taken into account in network division. Finally

simulation results in the New England system and part of Jiangsu power system show that the method proposed is able to effectively partition the power system with FCB units.
