Abstract
The invention belongs to the field of power grid operation monitoring management systems, and relates to a four-division line loss quasi real-time on-line monitoring scheme based on daily frequentness monitoring. The scheme particularly includes four line loss calculating links including area division line loss rate on-line calculating, voltage division line loss rate on-line calculating, line division line loss rate on-line calculating and district division line loss rate on-line calculating. Four-division management on the line losses is achieved, so that the method can be used for collecting basic data of the quality and the losses on line; related index calculation is carried out according to the collected data, and multi-dimensional and fine-grit management on on-line area-division, voltage-division, line-division, district-division and element-division line losses is achieved.
Description
Technical field
The invention belongs to power grid operation management system for monitoring field, relate to a kind of based on day frequency quartile damage quasi real time on-line monitoring scheme, the method obtains day 96 quasi real time Monitoring Data by state's net company operation monitoring system, in the line loss rate in line computation subregion, separated time, dividing potential drop and Fen Tai district, achieve the important breakthrough of line loss management in four divisions.
Background technology
There is many drawbacks in traditional Controlling line loss, monthly amount of power supply is gathered automatically by electric energy system, accurate.But the customer data that electricity sales amount is the person of copying and accepting to be made a copy of, because the time of checking meter has successively, indivedual employee lacks a sense of responsibility, and quality of checking meter has problems, so that the data distortion had, and the result of point folding must be given a discount in addition.The line loss analyzing cycle is 1 month, and during this period as there is stealing, metering decompression, the phenomenons such as defluidization, need could find by analysis to the end of month, and electricity lose.Meanwhile, the metering of the client user often that goes wrong accuses the process that is just on the scene, and work passive, the material require collection mass data in the regular meeting of preparation line loss analyzing, wastes time and energy, and be difficult to get a desired effect.Therefore the present invention proposes a kind of based on day frequency quartile damage quasi real time on-line monitoring scheme, the program obtains day 96 quasi real time Monitoring Data by state's net company operation monitoring system, in the line loss rate in line computation subregion, separated time, dividing potential drop and Fen Tai district, frequency will be monitored risen to " day " by " moon ", achieve the important breakthrough of line loss management in four divisions.
