基于层次分析法的电网网架结构综合评价模型研究

Research on Comprehensive Evaluation Model of Grid Structure Based on Analytic Hierarchy Process

摘要: 电网网架规划是电网建设的重要环节，合理的电网网架是保证电网安全、稳定、经济运行的有效手段，同时也是保证电力建设资金合理、有效、充分利用的重要前提。本文主要以扬州110 kV电网网架为例，采用层次分析法，建立网架结构的综合评价模型，该方法包括技术性、安全性、经济性和实施难易程度四方面指标，结合德尔菲法确定各指标权重，并采用模糊隶属度方法确定指标评分标准。该模型旨在排除评价过程中的主观因素，为电网网架结构提供一种合理的评价方法，对于提高电网规划水平、提高电网规划方案的适应性、把握电网发展方向、提高电网的经济和社会效益具有重大作用。

Abstract: Grid structure planning is an important link of power grid construction. The reasonable grid is an effective means to guarantee the safety, stability and economic operation of power grid, and also an important prerequisite to guarantee the reasonable, effective and full utilization of power grid construction funds. This paper mainly takes Yangzhou 110 kV grid structure as an example and adopts the analytic hierarchy process (AHP) to establish the comprehensive evaluation model of grid structure. This method includes four indicators: technical, safety, economic and ease of implementation. This model aims to eliminate subjective factors in the evaluation process and provide a reasonable evaluation method of the grid structure. It plays an important role in improving the adaptability of the grid planning scheme, grasping the development direction of the grid and increasing the economic and social benefits of the grid.
