摘    要:介绍南方电网两次黑启动试验的详细过程,分析了第一次黑启动过程中出现的两次因过电压发生线路跳闸的异常现象。提出将调速器切挟到手动模式调频,以及系统无功进相裕度不足是造成这两个异常现象的主要原因。认为,应选择合理的调节模式稳定黑启动过程中的系统频率、确保系统无功平衡并留足裕度、采用多种方式校核黑启动过程中的机组自励磁、尽早带负荷运行,以及实施多区域、多分区并举,低电压等级电网逐步启动后再实施分区并列的启动原则。给出了2007年补充试验的步骤和过程,试验验证了解决方案的有效性。

关 键 词:南方电网  黑启动  系统试验

Abstract:The process of two "black start" experiments in China Southern Power Grid are introduced, two abnormal over-voltage trippings in the first experiment is analysied. It is proposed that the frequency inverter being switched to manual mode, and the insufficient reactive power leading phase margin are the causes of two trippings respectively. It is proposed that a reasonable regulation mode should be selected to stable the system frequency during the "black start" process; reactive power balance should be maintained with sufficient margin; the operation should be loaded ASAP; multiple regions should be started simultaneously, and low voltage grids should be started step by step before turning into parallel operation. The process of the second experiment in 2007 is given, the effectiveness of the proposals is validated.
Keywords:China Southern Power Grid  black start  system experiment
