摘要
在前期针对不同地区负荷和地域分布特征的供电模型研究的基础上,采用计及不同线路利用水平因素的系数对供电模型的线路实际供电距离进行修正。综合考虑由于中压配电网主馈线分段开关的设置的可靠性效益与可靠性成本间的关系,基于单位负荷全寿命成本(SLCC)理念,对中压配电网远景目标网架规划中供电模型最优分段数进行实用化优化配置研究。
On the basis of the research of power supply models （PSM） in the light of the different characteristics in regions and load distribution, this paper puts forward a coefficient considering different line utilization level factor on PSM to correct actual line power supply distance. The research of optimal segmentation, which combines the invest- ment with the reliability benefit of the setting of the disconnect switches on the main feeder, is presented based on SL- CC theory to provide guidance to the planning of prospective target frameworks of MV distribution network.
