Abstract

In order to measure the power supply capacity of the distribution network and predict benefits and effects it brings to our society, we need an effective index system to evaluate the distribution network from multiple aspects. In this paper, aiming at the shortcomings of the existing distribution network evaluation index, we follow the general principle of index building to establish a comprehensive evaluation index system of power supply margin in distribution network, which includes four aspects: power supply capacity of the distribution network, investment economy, matching of the upper and lower levels and the balance of load. The index system is aimed at studying power supply capacity as the centre, combining other factors as an aid, to conduct a comprehensive scientific assessment for the distribution network. The significance of each index in the system is explained in detail. Then, based on a typical power supply model in a certain area of China, the application of index system and evaluation method is analysed. The results show that the proposed index system can reveal the operating condition of the distribution network and provide valuable guidance for power grid planning.

配电网供电裕度评价指标体系

为了衡量配电网的供电能力，预测配电网给社会带来的效益和影响，我们需要一个有效的指标体系，从多个方面对配电网进行评价。本文针对现有配电网评价指标的不足，遵循指标构建的一般原则，建立了配电网供电裕度综合评价指标体系，该指标体系包括配电网供电能力、投资经济性、上下级匹配性和负荷均衡性四个方面。该指标体系旨在以研究供电能力为中心，结合其他因素为辅助，对配电网进行全面科学的评价。详细说明了系统中各指标的意义。然后，以中国某地区典型供电模式为例，分析了指标体系和评价方法的应用。结果表明，该指标体系能较好地反映配电网的运行状况，为电网规划提供有价值的指导。
