一种基于图论搜索的限制短路电流分区方法
解开部分500kV/220kV电磁环网,对220kV电网进行分区是限制220kV电网短路电流短路的重要措施。针对目前依靠运行经验手动进行计算得到分区方案的局限,提出了一种限短路电流的电网自动分区算法。该方法以500kV主变负载尽可能均衡为目标,计及短路电流、线路输送功率、变电站下网潮流等约束,同时考虑电网拓扑结构、线路潮流等因素,基于图论搜索及Visual Studio调用PSASP进行求解。某市丰大方式下(2015年规划)220kV电网分区结果表明了所提算法的有效性。...

For the timitations of partitioning scheme retying on experience, this paper presents a grid partitioning algorithm about short-circuit current limitations. The goal of this method is to balance 500 kV transformer load, taking into account the constraints such as short-circuit current, lines' transmission power, substati |
