复杂配电网的简化建模和分析

详细介绍了配电网简化分析的各种方法，并给出了计算实例，这些方法包括负荷均匀分布模型、等效电压降落模型、等效线损模型、混合等效模型、变结构耗散网络模型。提出了一种全新的简化建模和分析方法－等效负荷模型。这种方法通过馈线两端的电压和流过馈线两端开关的功率反映馈线上的负荷及其分布情况，只需对变电站的出线开关、馈线分段开关和联络开关进行测量，而不必测量馈线上的配电变压器，就能得到满意的分析结果。

Simplified Modeling and Analysis of Compulicated Distribution Networks

Several simplified approaches are discussed to analyze distribution network, such as uniformly distributed load model(UDLM), voltage drop model(VDM), line losses model(LLM), hybrid model(HM), and structure variable dissipated network(SVDN). A novel simplified method, i.e., equivalent load model(ELM) is presented, in which the voltages and the power on/through both ends of the feeder are used to describe the load and its distribution within the feeder line. Only field test datum from feeder circuit breakers in substations, swithches along the feeder lines and on the loop points are needed to obtain a satisfied analysis result.
