摘　　要：针对含有单个或多个主电源并在负荷侧有大量分布式电源接入的双端供电配电系统结构特征和运行方式,提出含分布式电源和主电源的双端供电配电系统潮流计算的方法。在潮流计算的基础上,考虑并联电容器和负荷侧变压器运行方式的影响,从主电源和负荷侧分布式电源联合供电两种运行方式对含分布式电源和多主电源配电网供电适应性进行了分析。结合某区域配电系统的实际情况进行实例计算。Aiming at the structure characteristics and operation modes of double -terminals distribution system with single or multiple main power resource and with large amount of distributed generation injected in load demand sides,puts forward a method for power flow calculation of double-terminals distributed system with distributed generation and main power resource. On the basis of power flow calculation,considering the influence of operation mode of shunt capacitor and load side transformer,from two kinds of operation modes of main power resource single supply and main power resource and distributed generation of load side combining supply,analyzes the power supply adaptability of distribution system with distributed generation and multiple main power resource. A study example is carried out using the data of a Power Supply Bureau.
