Power metering system for power system

Abstract

The invention relates to a power metering system for a power system, which comprises a main data processor. A communication interface, a memory, a communication module, a button, a GPRS module, an LED display, a clock circuit, pulse output and an integrated metering chip are connected onto the main data processor; a voltage dividing circuit and an instrument current transformer are connected onto the integrated metering chip; and both the voltage dividing circuit and the instrument current transformer are connected with a user power grid respectively. According to the device of the invention, a distributed mode can be adopted for allocation, optimal resource allocation is realized, and accuracy for load prediction and line loss prediction can be improved; the fault analysis basis can be provided, online abnormal state analysis is realized, dynamic tracking and automatic control are realized, the power supply reliability is improved, and monitoring, prevention and maintenance of power grid elements, an intelligent electric energy meter and user equipment can be realized; and after the fault happens, through querying abnormal power utilization records, reliable real-time data can be provided for the fault data.

Description

technical field [0001] The invention relates to a power metering system of a power system, which belongs to the technical field of electricity metering. Background technique [0002] At present, the electricity consumption of household users is generally measured by directly checking the meter or using a digital chip card for metering. Certain card making costs, therefore, are not very adaptable in some places. At present, with the development of communication networks, more and more intelligent networks and measurement tools have appeared, which also provide some quickness and convenience for intelligent measurement. Therefore, intelligent methods can be used to control measurement and improve the efficiency and safety of measurement. sex, correctness. Contents of the invention [0003] The purpose of the present invention is to provide a power metering system of a power system, so as to more accurately, safely and quickly realize metering for power grid distribution, i...
