摘　　要：自然灾害等不可抗拒外力破坏可能会引起电网大面积崩溃,研究系统全停后的恢复过程有利于保障系统安全稳定运行,对提高电网供电可靠性具有重要意义。在江苏电网黑启动方案中参考相关黑启动技术规定和调度规定,研究并确定了江苏电网黑启动电源点,子系统划分、黑启动初始方式、黑启动路径及负荷的恢复过程。在以上黑启动方案基础上,基于BPA潮流及暂态稳定程序对黑启动过程中的潮流进行计算,对暂态稳定性进行校验,验证了黑启动方案的可行性。结果表明,江苏电网黑启动过程中暂态稳定性满足要求,电网可以顺利恢复供电。研究结果可以为相关管理部门制定调度操作原则提供参考,为调度运行人员处理事故提供依据。Natural disasters and other irresistible external damages may cause the collapse of power grid. The research on the recovery process after full stop is beneficial to guarantee the safety and stable operation of system, which has great significance to improve the reliability of power supply. The black-start power point, the subsystem division, the initial mode and path of black-start, as well as the load recovery process were studied and determined in the black-start scheme of Jiangsu power grid, based on the black-start technology and scheduling regulations. On this basis, the power flow during black-start process was calculated, the transient stability was checked, and the feasibility of black-start scheme was verified based on BPA. The results show that the transient stability of Jiangsu power grid during the black-start process can meet the requirements to successfully restore power. The research results can provide references for the authorities to make the rules of dispatch operation, as well as supply the foundation for dispatching and operating personnel to deal with incidents.
