交直流混合配电系统评价体系研究

Research on Evaluation System of AC/DC Hybrid Power Distribution Network

城市负荷密度快速增长对城市配电网供电能力及电能质量要求不断提高,以交流输电为主的城市配电网发展面临越来越大的困难和挑战,包含柔性直流输电线路的交直流混合配电系统必将成为解决城市配电网发展的有效途径之一。本文根据交直流混合配电系统的特点,分析交直流混合配电系统评价的影响因素,建立技术经济评价指标体系,并按照差异化的原则,确定了不同指标的分类评价标准。在此基础上,根据指标属性特点对指标进行了分类,给出了评价指标分值的实用化计算方法。

Fast growth of the city load density asks for higher capability of power supplying and improved performance of urban distribution network. The development of AC power distribution network is facing more and more difficulties and challenges, and AC/DC Hybrid Power Distribution Network using VSC HVDC technology will become one of the effective ways to solve the urban distribution network development. According to the characteristics of AC/DC hybrid power distribution network, this paper analyzes the influence factors in evaluating the ac/dc hybrid power distribution system. The evaluation system included the technical and economic evaluation indexes for AC/DC hybrid power distribution network is proposed. According to differentiation principle, evaluation standards of different indices are determined. Then, the practical calculation method for the scores of evaluation indices is given through the classification on evaluation indices based on its properties.
