摘　　要：县城配电网规划是根据规划期间的县城负荷增长及电源规划方案确定相应的最佳10 kV电网结构,以满足经济、可靠的输送电力要求。县城电网规划可以使县城电网在现有基础和水平上有目标、有计划地健康发展。采用人工拟定方案,再加上计算机辅助进行计算分析,对重庆某县城的电网进行规划。本次规划涉及负荷预测、网架规划及投资费用的估算。实际应用表明,该方法具有较强的实用性。In urban distribution network planning , based on the corresponding load growth and substation planning , the optimal 10 kV network structure is determined in order to meet the requirements of economic and reliable power transmission .Urban network planning can result in a healthy development of urban power grid in a planned way based on the existing infrastructure and level .A traditional planning method is used , which combines artificial schemes and computer -aided calculation and a-nalysis.The planning for an urban power grid in Chongqing is taken for an example .The planning involves load forecasting , network planning and investment cost evaluation .The real application shows that the proposed method is very practical .
