Problems solved by technology

[0006] At present, the operation and maintenance personnel of Huanggang Power Supply Company mainly use traditional manual search and analysis to locate meter faults, but this method has several disadvantages: first, the workload is heavy, and some maintenance personnel have multiple jobs The second is that the efficiency of meter fault finding and positioning is low. When a problem occurs, it often requires various analysis to finally determine the faulty meter, which cannot meet the requirements of rapid response.

Embodiment Construction

[0023] In 2004, we selected the 110Kv Gong02 gate metering switch of the 110kV Gongjiahe Substation of Huanggang Power Supply Company in Hong’an County to compare the zero-point electricity in August 2014. We found that the meter code of the meter was collected through the integrated electricity of the EMS system and the TMR system The daily error of the power is between -1.12% and 0.9%, and the monthly cumulative error is 0.003%, so it can be judged that the integrated power of the EMS system can be used as the basis for the reference of the power of the meter code. The specific data are as follows:

Abstract

The invention discloses a method of monitoring whether metering is correct or not by using a system for comparing and analyzing a remotely-read electric quantity and an integral electric quantity, so as to solve the problem that quick response can not be achieved due to the traditional manual searching and locating operation by the existing operation person mainly. A remotely-read electric quantity and integral electric quantity comparing and analyzing system software is used for managing a to-be-monitored electric energy metering gateway. The method of the invention mainly comprises the following steps: (1) power system telecontrol equipment acquires network transmission data of a power grid dispatching automatic system and an electric energy system; (2) integral electric quantity calculation is carried out on power data acquired by the power grid dispatching automatic system; (3) comparison of two values of the integral electric quantity and the meter code electric quantity is realized in an online mode to obtain a fault metering point and a metering point for influencing electric quantity balance; and (4) all-direction metering operation monitoring is realized to further achieve purposes of improving the metering managing work efficiency and scientific management.

Description

1. Technical field [0001] The invention belongs to a management method for electric energy metering in an electric power system, and in particular relates to a method for monitoring whether electric energy metering is correct or not by using a comparison and analysis system for remote reading electric quantity and integral electric quantity. 2. Background technology [0002] 1. Status of TMR (electric energy system) and EMS / SCADA system [0003] With the accelerated construction of electronic enterprises of Huanggang Power Supply Company, EMS / SCADA system and TMR system have been put into practical operation one after another, providing basic data for electric energy measurement management. Among them, the EMS / SCADA system not only realizes the remote measurement, remote viewing, remote signaling, and remote control functions required by power dispatching, but also can obtain the integral power through the integral calculation of the load through this system. The TMR system...
