摘　　要：发电机组黑启动可能会对电网系统产生巨大的冲击破坏。当前,电力系统对安全生产提出更高的要求,安全、可靠并平稳地进行黑启动关系到电网系统的安全运行。该研究基于电磁暂态仿真软件(PSCAD),建立发电机组的黑启动模型,对黑启动过程进行自励磁的可能性、空充长线的电压问题及合空载变压器操作过电压问题进行仿真计算,验证发电机黑启动方案的可行性。结果表明,黑启动没有产生自励磁现象,空充长线电压在允许的安全范围内,同时合空载变压器操作电压符合技术要求。仿真结果表明,黑启动方案可行。The black start of the generator set may have a great impact on the power grid system.At present,the power system puts forward higher requirements for safe production,safe,reliable and stable black start is related to the safe operation of the power grid system.In this study,based onPSCAD(Power System ComputerAided Design),an electromagnetic transient simulation software,the black start model of the generator set is established,and the possibility of self-excitation in the black start process,the voltage problem of the long empty charge line and the switching overvoltage of the closed no load transformer are simulated and calculated to verify the feasibility of the generator black start scheme.The results show that the black start does not produce self-excitation,the long line voltage of empty charge is within the allowable safe range,and the operating voltage of no-load transformer meets the technical requirements.The simulation results show that the black start scheme is feasible.
