A qrnn-based method for estimating the reasonable range of line loss rate in low-voltage station area

Abstract

The invention discloses a QRNN-based method for estimating the reasonable range of the line loss rate of the low-voltage station area in the field of line loss rate technology, aiming to solve the problem that the evaluation basis of the line loss rate in the prior art cannot reflect the structure, power supply range, and load level of the station area Based on the existing power management system to collect operating data of the station area, the factors affecting the line loss rate of the station area are screened out; the correlation analysis is carried out on the line loss rate of the station area, and the line loss rate that affects the line loss rate is extracted The key factor; based on the neural network quantile regression model, the reasonable range of the line loss rate of the low-voltage station area is calculated; according to the calculated reasonable range of the line loss rate of the specific station area, it is diagnosed whether it is an abnormal station area, and it is adjusted. The method of the present invention is based on the actual operation data of the existing electricity information system, marketing system, PMS system, etc., extracts the key factors affecting the line loss rate, and can give a reasonable range of the line loss rate for a specific station area, for It provides a reliable basis for diagnosing the abnormal line loss area.

Description

technical field [0001] The invention belongs to the technical field of line loss rate, and in particular relates to a method for estimating a reasonable range of line loss rate in a low-voltage station area based on QRNN. Background technique [0002] The electric energy produced by power plants in the power system is supplied to users through the transmission, transformation and power supply links of the power grid. In the process of transmitting and distributing electric energy, each element in the power network (such as transformers, transmission lines and protection devices, etc.) consumes a certain amount of electric energy. [0003] A low-voltage station area refers to the power supply area or area of ​​a distribution transformer. The range of line loss calculation in the low-voltage station area starts from the watt-hour meter installed at the outlet of the distribution transformer in the station area, and ends at the electric energy meter of each user. Within this ...
