      基于最大供电能力的配电网分区方法

      A Distribution Network Partition Method Based on Total Supply Capability

      摘要:
      在供电能力理论的基础上对配电网络进行了分区方法的研究,首先介绍了联络有效性的概念,通过对配电网络进行联络有效性分析,定位网络中对供电能力贡献较小的联络和联络组合.其次提出了最优分区的概念,介绍了最优分区的判据,并提出了筛选配网最优分区方案的2种方法,即基于最大供电能力的方法和穷举法. 然后对这2种方法进行对比,明确其适用的范围.最后,在算例电网中的实际验证也说明了提出的基于配网最大供电能力的优化分区方法正确并且可行.
      Abstract:
      Based on total supply capabihty,a distribution network partition method is introduced.The definition of connection effectiveness is presented first.Based on analysis of connection effectiveness in distribution network,connections or connection-combinations that contribute less to power supply capability are located.Next,concept of optimized partition is proposed.The judgment basis and methods are also introduced.Two optimal partition schemes,TSC based method and exhaustive search method,are analyzed in detail.The two procedures are compared,and their applicable scopes are discussed.The simulation results on testing system prove the correctness and validity of proposed TSC based method in partition optimization.
