摘    要:介绍了电力系统稳定计算分析程序中常用的负荷模型,分析了上述负荷模型的结构及其在电力系统计算分析程序中的实现过程,指出了上述负荷模型的不足。根据变电站负荷的实际构成,提出了物理意义明确的综合负荷模型。该模型物理结构合理,可操作性强,可方便地模拟负荷元件和包括配电网络、无功补偿系统和接入低压电网的发电机的供电系统。2004年和2005年东北电网的4次三相短路试验验证了该综合负荷模型的有效性。

关 键 词:综合负荷模型  电力系统  仿真  配电网

Abstract:The load models for power system simulation in the different power utilities are introduced. The structures of these load models and their implementations in power system simulation programs are analyzed, and the insufficiencies of the exiting load models are pointed out. Based on the analysis of the existing load models, a synthesis load model (SLM) with distribution network, which is consistent with the structure of power substation loads, is presented. The SLM is reasonable in structure and convenient in use. SLM can simulate the load components and distribution system including distribution network, var compensation and the generators connected to low voltage networks. The validity of SLM is validated by four field tests of three-phase short circuit in Northeast Power Grid of China in the years of 2004 and 2005 respectively.
Keywords:synthesis load model  power system  simulation  distribution network
