Power distribution area low voltage cause evaluation method and device

Abstract

The embodiment of the invention discloses a power distribution area low voltage cause evaluation method and device, and the method comprises the steps: determining a plurality of voltage evaluation indexes of a to-be-evaluated power distribution area, and enabling the voltage evaluation indexes to be obtained based on the collected measurement data and ledger data of the to-be-evaluated power distribution area; determining a weight corresponding to each voltage evaluation index by using the voltage evaluation indexes and an index weight determination method; according to the weight corresponding to each voltage evaluation index and the voltage deviation value, determining the correlation degree between each voltage evaluation index of the to-be-evaluated power distribution area and the voltage deviation value; and performing low-voltage cause evaluation on each voltage evaluation index by using the correlation degree, and determining a main cause of a low-voltage phenomenon corresponding to the to-be-evaluated power distribution area. Through the method, real-time evaluation of the low-voltage cause of the power distribution area can be realized, the main cause of the low-voltage phenomenon corresponding to the power distribution area is determined by using the correlation degree, and a reliable basis can be provided for voltage quality evaluation of a power distribution network in a rural area.

Description

technical field [0001] The invention relates to the technical field of voltage optimization in a distribution station area, in particular to a method and device for evaluating the causes of low voltage in a distribution station area. Background technique [0002] The governance of low voltage problems in distribution network stations is an important issue related to power quality. In recent years, with the economic development, the demand for power quality in rural areas in my country is getting higher and higher, but the construction of distribution network is relatively backward. Work. There are many factors that cause the problem of low voltage in the distribution network. Due to the constraints of manpower and material resources, it is imperative to deal with the main problems of low voltage in combination with the current situation of the rural grid. Therefore, it is necessary to evaluate the main causes of low voltage in Taiwan. [0003] There have been studies on low...
