含源网荷的智能配电网运行仿真平台研究及应用

摘要

考虑配电网存在的源网荷不对称现象、特殊网络结构的基础上,建立了配电网常规元件及分布式电源的稳/暂态模型.针对智能配电网三相不对称的特性,研究了智能配电网相关的三相潮流算法、三相短路电流算法以及三相时域仿真算法.最后,开发了基于OPEN3200系统接口的智能配电网运行仿真平台,并在南京河西新城进行了成功应用,验证了所提方法及研制系统的合理性、有效性.%Considering the phenomenon of asymmetric and special network structure, a distribution network of conventional components and steady/transient model of distributed power supply are established.The intelligent distribution network related algorithm of three-phase flow algorithm, three phase short circuit current and three-phase time-domain simulation algorithm are proposed based on the characteristic of three-phase asymmetric distribution network.Finally, simulation platform of intelligent distribution network is developed, which is applied in Nanjing CBD successfully, verifying its effectiveness and rationality.
