摘　　要：配电网的接线模式从单辐射馈线发展到手拉手环网接线和多点联络接线,正常情况下配电负荷具有多种供电方式可供选择,但目前配电网通常以固定方式运行。通过实际配电网接线和运行方式分析,提出配电网运行方式进行调度的必要性和可行性。通过不同时间段各类负荷的互补性分析和临时供电对配电网运行方式影响的仿真计算,表明考虑工作日和节假日负荷的变化规律、临时供电需求进行配电网运行方式调度有助于提高配电网的运行效率,是配电网调度的发展趋势。The wiring mode of distribution network has developed from the single radiation feeders to the hand-in-hand loop wiring and the multi-point contact wiring. The load under normal circumstances has a variety of choices of power supply modes. However, presently the distribution network usually operates in a fixed mode. The necessity and feasi- bility to dispatch the distribution network operation mode are emphasized. Based on the operation mode analysis of the actual distribution networks. Through the complementary analysis of various loads in different time periods and the influence simulation of the temporary power supply on the distribution network, this research concludes that with regard to the load variation regularity during the working days and holidays and the temporary power supply requirements, the operation mode dispatch in distribution network helps to improve the operating efficiency of distribution network and will be a trend of distribution network dispatch development.
