首先介绍了辐射状配电网三相潮流计算方法，对几种常用的配电网潮流计算方法进行了对比分析，着重介绍了配电网潮流计算中常用的前推回代法的基本原理，并利用Matlab仿真软件编写了相应的潮流计算程序，通过33母线系统对计算程序进行了仿真验证。然后介绍了含弱环网的配电网潮流计算的处理方法，编写了相应的仿真计算程序，并通过算例仿真予以验证。接着介绍了分布式电源并网的几种接口模型以及分布式电源在潮流计算中的数学模型，分析了在潮流计算过程中PQ、PV、PI节点的处理方法，特别是对PV节点的处理方法进行了详细的介绍。最后针对不同分布式电源并网的状况分为四种方案进行了仿真测试，验证了本文所编写的潮流计算方法在处理计及分布式电源的配电网三相潮流的正确性。(First introduced the radial distribution network three phase power flow calculation method for several common distribution power flow calculation methods were compared, highlighting distribution power flow calculation of the basic principles of common forward and backward substitution method, and the use of Matlab simulation software written in the corresponding flow calculation program, through the system bus 33 to a simulation calculation program. Then introduces the method of treating a distribution power flow calculation weak ring, write the corresponding simulation program and simulation to be verified by an example. Then interface model introduces several distributed power grid and distributed power flow calculation in mathematical models, analyzes the trends in the calculation process PQ, PV, PI node processing method, especially for PV node approach a detailed description. Finally different distributed power grid situation is divided into four scenarios simulation test to verif)
