Distribution network power supply area division method based on comprehensive evaluation

Abstract

The invention relates to a method for distribution system planning and particularly relates to a distribution network power supply area division method based on comprehensive evaluation. The method comprises the following steps: first, a power supply area to be divided is selected, the status of the power supply area and main factors influencing power supply area division are analyzed and an evaluation index system for power supply area division is established; then, an appropriate method is selected to set weights of evaluation indexes and evaluation standards; and finally, comprehensive evaluation is carried out to determine a division result of the power supply area. The method overcomes the defect that the prior method carries out qualitative classification only based on experiences of experts or leaders. Based on factors influencing distribution network power supply area division, a comprehensive evaluation method is fully utilized and the defect that power supply area division can only be carried out on the basis of quantitative indexes in a clustering analysis method is overcome. The power supply area can be comprehensively evaluated, the weights of the indexes can be adjusted according to actual situations of various regions, the accuracy of the method is greatly improved, and the method has very high engineering application values.

Description

technical field [0001] The invention relates to a method for power distribution system planning, in particular to a method for dividing power supply areas of a power distribution network based on comprehensive evaluation. Background technique [0002] China has a vast territory and a large power supply area, and the economic and social development and power grid characteristics of different regions are obviously different. If the distribution network is built according to a unified standard, the utilization rate of equipment assets will be low or even serious waste, which is unreasonable in terms of technology and economy. Therefore, in order to reflect regional differences and differences in distribution network planning and construction, realize lean management of distribution networks, improve the efficiency and level of distribution network planning, and promote the development of my country's distribution network planning to standardization and science , should always r...

Problems solved by technology

[0012] (1) It is difficult to reasonably define the evaluation index factors and weights

It is more complicated to determine the evaluation index factors and weights, and it is not easy to be scientific and reasonable;

[0013] (2) Evaluation index experts are not suitable

On the basis of a large amount of extensive information, the collective wisdom of experts can be concentrated, and finally a practical and reasonable consultation result can be obtained; the main disadvantage of the Delphi method is that it may take a long time and consume more manpower and material resources; Key to the approach is the determination of expert team membership and size
