AI Technical Summary

Problems solved by technology

However, since the analysis of the voltage pass rate requires multi-dimensional data support, it is often difficult to perform the analysis in the absence of effective analysis methods and tools and the technical quality of the basic-level operators of the power grid is generally not high.
At present, there is no auxiliary analysis method and system for voltage qualification rate on the market.

Abstract

A comprehensive analysis method for the qualified rate of power supply voltage, which is characterized in that it includes the following steps: S1: select the voltage monitoring point category A, B, C, D; S2: input the relevant parameters of the analysis to form a basic mathematical model; S3: input the relevant S4: Execute the analysis process, if the exact reason cannot be obtained at the end, start manual analysis; S5: Store the analysis results and form the analysis conclusion. Through the method, the complex and multi-factor-affected voltage qualification rate analysis can be simplified and decoupled, and the accuracy and efficiency of the analysis can be improved.

Description

technical field [0001] The invention relates to a comprehensive analysis method for the qualified rate of power supply voltage. Background technique [0002] The qualified rate of power supply voltage is the percentage of the time when the voltage value is in the qualified range within the statistical time, and it is one of the important indicators for evaluating the quality of power delivered by the power supply enterprise to the receiving end user. [0003] The power supply voltage qualification rate statistics include four types of monitoring points, such as figure 1 shown. [0004] Class A monitoring point: set up in the substation area with a load of 10 (6, 20) kV bus, the qualified range is 0~+7%; [0005] Class B monitoring points: set at 20kV, 35kV, 66kV dedicated line power supply users and 110kV level or above power supply users; the sum of the absolute values ​​of the upper and lower limits of the qualified range shall not exceed 10%; [0006] Class C monitorin...
