传统的电网规划方法中未综合考虑所规划电网实施建设中的一些不确定因素，如施工条件、周围环境等，使得规划成果难以完全实现。提出一种基于电网建设边界因素的城市配电网规划方法，在规划变电站的位置、容量及供电范围时，需综合考虑负荷发展、电网建设条件等边界因素；然后再根据选址定容结果进行20/10 kV线路出线、中压配变容量、开关台数以及无功补偿估算；最后进行规划方案的评估、校验、修正等。应用结果表明，该方法符合工程实践，具有一定的实用性。

Some uncertain factors of the power grid, such as construction conditions, surrounding environment,etc., are not considered in traditional network planning methods, so that it is difficult to achieve the expected results. A new urban distribution network planning method is proposed, where the boundary elements including load development and power grid construction conditions are considered in determining the locations, capacities and service area of the substations. Then according to the locations and the capacities of substations, the 20/10 kV lines, the medium voltage distribution transformer capacities, the numbers of switching units and the reactive power compensation capacities are estimated. Finally, the assessment, validation and correction of the planed program are implemented. The application results show that the approach is consistent with engineering practice, which has a certain practicality.
