【摘要】：配电网规划是保证电力系统可靠运行的重要工作之一。配电网规划综合效益评估有利于指导规划方案的决策,是选择配电网规划方案的重要依据。因此,对配电网进行科学合理的规划改造和评价是电力系统研究的重要课题。本文首先对泰州市的经济社会发展情况、区域供电概况等情况进行了介绍,总结归纳出泰州市配电网目前所存在的问题;其次对泰州市的负荷特性及负荷增长趋势进行分析,对负荷和用电量进行预测;根据配电网各个电压等级下的规划技术原则,在泰州市配电网现状的基础上,对泰州市配电网络进行规划;最后结合配电网自身特点,全面考虑配电网经济效益指标的影响因素,构建了配电网规划效益评估指标体系,运用熵权法计算效益指标的权重。通过对泰州市配电网规划方案进行效益评估,结果表明建立的评价模型可以准确地对泰州市配电网规划进行评价分析。
[Abstract]:Distribution network planning is one of the important tasks to ensure the reliable operation of power system. The comprehensive benefit evaluation of distribution network planning is helpful to guide the decision-making of the planning scheme and is an important basis for selecting the distribution network planning scheme. Therefore, scientific and reasonable planning and evaluation of distribution network is an important subject of power system research. Firstly, this paper introduces the economic and social development of Taizhou City, regional power supply situation, and summarizes the existing problems of distribution network in Taizhou City. Secondly, the load characteristics and load growth trend of Taizhou City are analyzed, and the load and electricity consumption are forecasted. According to the planning technology principle of distribution network under each voltage grade, the distribution network of Taizhou city is planned on the basis of the present situation of distribution network in Taizhou city. Finally, considering the influence factors of distribution network economic benefit index, the evaluation index system of distribution network planning benefit is constructed, and the weight of benefit index is calculated by entropy weight method. The results show that the evaluation model can accurately evaluate and analyze the distribution network planning of Taizhou.
