QRNN-based reasonable range estimation method for low-voltage transformer area line loss rate

Abstract

The invention discloses a QRNN-based reasonable range estimation method for low-voltage transformer area line loss rate in the technical field of line loss rates. The method aims to solve the technical problem that in the prior art, the line loss rate evaluation basis cannot reflect the difference of a transformer area in structure, power supply range and load level, and comprises the steps of collecting transformer area operation data based on an existing power utilization management system, and screening out transformer area line loss rate influence factors; correlation analysis is carried out on the line loss rate of the transformer area, and line loss rate key factors influencing the line loss rate are extracted; calculating a reasonable range of the line loss rate of the low-voltage transformer area based on a neural network quantile regression model; and according to the calculated reasonable range of the line loss rate of the specific transformer area, diagnosing whether the transformer area is an abnormal transformer area, and adjusting the transformer area. Key factors influencing the line loss rate are extracted on the basis of actual operation data of an existing power utilization information system, an existing marketing system, an existing PMS system and the like, the reasonable range of the line loss rate can be given for a specific transformer area, and a reliable basis is provided for diagnosing a transformer area with abnormal line loss.

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 the power plant in the power system is supplied to the user through the transmission, transformation and power supply links of the power grid. In the process of transmitting and distributing electrical energy, each component in the power grid (such as transformers, transmission lines and protection devices, etc.) consumes a certain amount of electrical energy. [0003] A low-voltage station area refers to the power supply range or area of ​​a distribution transformer. The scope 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 to the watt-hour meter of each user. Within this range,...
