解开部分500 kV/220 kV电磁环网,对220 kV电网进行分区是限制220 kV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500 kV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)220 kV电网分区结果表明了所提算法的有效性。

Breaking part of 500 kV/220 kV electromagnetic loop network and 220 kV network partition operation is an important measure to limit the short-circuit current of 220 kV bus. For the limitations of partitioning scheme relying 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, substations’ power, network topology and line power flow. This problem is solved by graph theory search and Visual Studio calling PSASP. Based on the data of a city power grid plan of 2015, the grid partitioning results show that the proposed algorithm is effective.
