Power distribution network health degree self-diagnosis method with consideration of regional difference

Abstract

The invention relates to a power distribution network health degree self-diagnosis method with consideration of regional difference. Objects influencing the operation state of a power distribution network are obtained to serve as first-grade objects, second-grade objects and third-grade indicators are obtained, and a tree-shaped power distribution network operation state system is established. Weighted values of the objects and indicators in different grades are determined according to the analytic hierarchy process. Scoring function types of the three-grade indicators are determined, and scoring formulas of the three-grade indicators are given according to an evaluation reference value and a largest value or a smallest value. A comprehensive score of the power distribution network is solved according to the scoring formulas of the indicators, namely the weighted values of the objects of indicators in various grades. A weak link in the power distribution network is searched for according to the comprehensive score of the power distribution network, and corresponding improvement measures are carried out. By means of the power distribution network health degree self-diagnosis method with consideration of regional difference, regional difference is fully considered in the process of search for the weak link, the real weak link in the power distribution network is found with the combination of regional characteristics, and technical support is provided for safe operation of the power distribution network.

Description

technical field [0001] The invention relates to a method for self-diagnosing the health degree of distribution network considering regional differentiation. Background technique [0002] As an important social infrastructure, the power grid plays an important role in optimizing resource allocation, ensuring energy security, and meeting the needs of economic and social development. It must have a reasonable structure, flexible operation, and be able to provide safe, reliable, high-quality, and efficient power supply. At the same time, in order to achieve scientific development of the power grid, the power grid enterprises, as the main body of grid investment and construction, must maintain certain profitability and sustainable development capabilities. [0003] The distribution network is the link that directly faces the users in the power system, and has the most direct impact on the quality and reliability of the power supply of the users. The power supply capacity and pow...

Since the reform and opening up, especially since the 1990s, my country's economy has developed rapidly and its economic strength has been significantly enhanced. However, there are also obvious economic differences between the eastern coastal areas and the backward areas in the central and western regions. The rapid development is in stark contrast. The unbalanced development of the region makes this gap gradually widen. There are imbalances in the industrial structure and per capita GDP of the eastern, central and western regions.
