农村配电网规划项目可靠性提升效果评估方法

Evaluation Method for Reliability Improvement Effect of Rural Distribution Network Planning Project

[目的]规划项目供电可靠性提升效果的量化评估工作是以二级指标为规划导向的。为了解决农村配电网规划缺乏量化评估的问题,文章提出了一种适用于农村配电网大规模规划项目可靠性提升效果快速评估的方法,实现对规划项目可靠性提升效果的快速评估。[方法]文章从农村配电网主要的特点分析出发,结合配电网规划项目供电可靠性提升效果评估需求,基于简化拓扑,提出适用于农村配电网的规划项目供电可靠性提升效果评估方法。[结果]通过与中压配电网可靠性评估行业标准进行对比,计算精度误差在11%以内。[结论]所提方法实现具备一定的计算精度,能够满足对农村配电网大规模规划项目可靠性提升效果快速评估,有效提升配电网规划质量。

[Introduction]Quantitative evaluation for power supply reliability improvement effect of planning projects is guided by secondary indexes.In order to solve the problems that the planning of rural distribution network is lacks,this paper proposes a rapid evaluation method for reliability improvement effect of large-scale rural distribution network planning projects.[Method]This paper first analyzed the main characteristics of rural distribution network.Then,based on the evaluation requirements of power supply reliability improvement effect of distribution network planning project and a simplified topology,this paper proposed an evaluation method for power supply reliability improvement effect of rural distribution network planning projects.[Result]The proposed method is compared with the industry standard for reliability evaluation of medium-voltage distribution networks,and the calculation accuracy error is within11%.[Conclusion]The proposed method achieves a certain computational accuracy.It can meet the needs of rapid evaluation of reliability improvement effect of large-scale rural distribution network planning projects,and effectively improve the quality of distribution network planning.
