摘要：

为解决传统的区域配电网规划评估一般仅考虑经济性、评估不够全面的不足，综合考虑中低压配电网整体规划方案的技术、经济水平及企业的供电义务因素，从供电裕度、电网安全、服务水平、经济效益四个方面构建综合评估指标体系，并引入公共服务价值模型建立综合评估模型，实现对中低压配电网整体规划方案的科学评估。指标体系构建及方案评估过程遵循差异化原则，即以Q/GDW 1738—2012《配电网规划设计技术导则》中供电分区为基础，差异化设计评估指标、设置指标权重及评分标准，同时指标评分采取存量值与增量值综合评分方法，解决不同区域由于电网基础现状、供电需求、发展目标不同导致的投资敏感性的差异。实际算例表明，所提出的方法能够有效指导区域中低压配电网规划中资源科学优化配置，引导规划方向。

Abstract:

The traditional assessments of regional distribution network planning only focus on economy resulting in that the assessments are not comprehensive. To solve the problem， the paper constructed a comprehensive evaluation index system from four aspects of power supply margin， network security， service level and economic benefits， with considering the factors of the technical and economic level and the power responsibility of enterprise in the overall planning scheme of medium-lower voltage distribution network. And the comprehensive evaluation model was built based on the PSV （public service value） model， which could realize the scientific evaluation for the overall planning scheme of medium-lower voltage distribution network. The index system construction and evaluation process follows the principle of differentiation， which designs the evaluation index and set up the index weight and evaluation criterion in differentiation， based on the power supply zone in ‘the guide of planning and design of distribution network’ （Q/GDW 1738-2012）. Meanwhile， the index scoring adopts the comprehensive scoring method of stock value and increment value. So the investment sensitivity difference in different regions caused by the differences in the current situation of network， the power supply demand and the development goals can be solved. Actual examples show that the proposed method can effectively promote the optimal allocation of resource science in medium-lower voltage distribution network planning， and guide the planning direction.

Key words: overall planning, comprehensive evaluation index system, PSV model, differential design
