摘　　要：对黑启动初期由水轮发电机对空载长线路充电过程中,发电机产生自励磁的物理过程进行了分析,同时通过建立仿真模型,在使用状态空间法判断机组自励磁情况的基础上,对其暂态过程进行仿真分析.仿真结果可以为运行人员提供直观的认识,从而采取措施抑制自励磁的发生,确保黑启动的成功进行.By means of the result of analyzing the physical process of the self - excitation in the early stage of the black start when the hydraulic generator charges the no - load long high voltage transmission line, and by building the mathematical models of the system, the transient process of generator was simulated and analyzed after using the state - space method to judge the type of the self - excitation. Based on the simulative results, the operator can form the intuitionistic cognition of the problem, and take some appropriate measure to restrain the self - excitation then ensure the success of the black start.
