Method for analyzing weak links of power distribution network status

Abstract

The invention provides a method for analyzing weak links of the power distribution network status. The method includes the steps of analyzing characteristics of a regional power distribution network, establishing a power distribution network status weak link analysis index system, collecting power distribution network status data corresponding to all indexes in the analysis index system, checking and analyzing the power distribution network status data in the analysis index system item by item so as to find out the weak links of the power distribution network status and other steps. The method has the advantages that when the weak links of the power distribution network status are analyzed, the single problem of existence of the power distribution network is considered, and the integrality and the sustainable development of the power distribution network are considered simultaneously, so the analysis method is more scientific and comprehensive; the method provides a beneficial reference for power distribution network planners to analyze the weak links of the power distribution network status, and provides a powerful technical support for power distribution network planning work in the future; the index system is easy to master and operate, power distribution network construction target making, power distribution network status data acquisition and the like can be easily understood, and the index system can be conveniently mastered by actual operation personnel.

Description

technical field [0001] The invention belongs to the technical field of power distribution network control, and in particular relates to a method for analyzing weak links in the current distribution network. Background technique [0002] In the power system, the currently commonly used weak link analysis methods of the distribution network status only focus on a certain aspect of the distribution network status, but lack a system. In addition, it uses the strength index of the grid structure of the distribution system and the overall security index of the distribution system as the basis for the static security analysis of the distribution network. A comprehensive assessment of the technical and economic rationality of the power grid based on its level and changes. [0003] Another analysis method is the distribution network reliability analysis method. This method proposes that evaluating the economic reliability index can ensure that the power grid has good economic benef...

This method points out that the economic equivalent of safety and reliability measures is the difference between the economic benefits that can be brought by the implementation of a certain safety measure and its implementation cost, that is, the implementation benefits of safety measures, but its disadvantage is that it has little guiding significance for actual work. Obviously, the evaluation work has not been well integrated with the main business of the power company, and the evaluation results have not been fully utilized.
