【摘要】 随着城市建设的发展,配电网负荷不断增加,网络结构越来越复杂,用户对供电可靠性和电能质量的要求越来越高。配电网络重构是提高电网运行效率、供电可靠性和供电质量的有效手段,根据配电网络的结构特点提出一次搜索可以确定多个独立拓扑调整的改进支路交换算法。对于一次拓扑调整,算法通过选择电流最接近理想转移电流的支路开断,以较快的速度得到(近似)全局最优解。本文在研究此算法的基础上,辅以实际算例进行检验,验证了该算法的可行性与可靠性。更多还原

【Abstract】 With the development of city building,the load of distribution is continuously increasing.Users’requirements for reliability of power supply and quality of electricity are more and more strict.Reconfiguration of distribution networks is an effective method to improve running efficiency of power network,reliability and quality of power supply.By the structure characteristics of distribution network,it puts forward improved branch exchange method which can do several modulations by one search.For one modulation,the algorithm selects the branch to cut whose current is most close to the optimal transfer current. It can get the optimal results with fast speed.The paper uses an example to verify the algorithm’s feasibility and reliability on the basis of the algorithm’s research.更多还原
