摘　　要：电力系统发生大停电事故后,采用分区并行恢复策略可以有效加快系统恢复速度。针对分区并行恢复问题,提出了电力系统黑启动分区的两步策略。其中,第一步建立待恢复机组的分组模型,其以待恢复机组获得恢复功率所需时间最小为目标,从而保证机组的快速启动;第二步建立电力系统图分区模型,目标是使得各黑启动分区在满足一定的约束条件下分区间的联络线数最少以及联络线的有功功率绝对值之和最小。然后,利用商用线性规划求解器ILOG CPLEX求解所提出的两步策略数学模型。同时,为了减少求解工作量,提出了可以尽可能减少线路信息丢失的拓扑图简化原则。最后,以新英格兰10机39节点系统为例说明了所发展的模型和方法的基本特征。The parallel restoration strategy is used to speed up the power system restoration after blackout,for which,a two-step strategy is proposed for the black-start zone partitioning. In the first step,a grouping model of generators to be restored is built with the minimum generator restoration time as its objective to guarantee the fast unit startup. In the second step,a partitioning model of power system map is built with the minimum tie-line quantity and the minimum absolute active power summation as its objectives for the black-start zone partitioning with certain restraints. The well-developed commercial tool ILOG CPLEX is adopted to solve two models and a network topology simplification principle is proposed to keep the line information as much as possible while reduce the computation load. The New England 10-unit 39-bus system is employed to demonstrate the developed models and method.
