摘　　要：随着国民经济的快速发展,大容量用电设备逐年增加,尤其是超高功率交流电弧炉,由于运行工况的变化,造成负荷的巨幅频繁变化,有可能影响电力系统临近发电机组的正常运行。针对冲击负荷对邻近发电机组的冲击功率分配的问题,分析了冲击发生后t=0+和t=t1时刻,即调速器动作之前的冲击功率分配情况,并且对t>t1调速器动作之后冲击功率的分配问题进行了分析,提出了改进措施,最后通过某地区实际电网验证了分析结论的正确性和可行性。With the development of national economy, a large amount of equipments have become into use,especially the ultra high power AC electric arc furnace. Due to the change of the operation condition,the load changes seriously and frequently so that the adjacent plant generator units could not operate normally. This paper analyses the assignment of the impact power on generator units at the moment of t=0＋and t=t1,that is before governor actions,and the situation is analyzed after governor actions at the period of t〉t1. The relative measures are presented. At last,taking a certain regional power system in China for the object to be researched,the correctness and feasibility of the proposed method are validated.
