Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0019] Such as figure 1 , 2 As shown, a substation electric energy balance monitoring system includes a master station system, a concentrator, and a collection terminal; wherein the master station system includes a database server, an application server, and a front-end processor. The function of the master station system is to send instructions downward to read and write the parameters and data of the concentrator and the collection terminal, and establish its own database to save the data; the front-end processor provides the function of data forwarding; the function of the collection terminal is to collect real-time power data; The concentrator has the functions of AC sampling and meter reading, and can periodically save the relevant data of the power grid, and forward the collected data to the master station system.

[0020] The electric energy...

Abstract

The invention can build a curve for monitoring electric energy balance in real time for each transformer station at a dispatch centre through an electric energy balance monitoring system provided with a main station system, a concentrator and an acquisition terminal. When electric energy metering equipment of the transformer station normally run, the electric energy balance curve is a relatively flat curve; and when the electric energy metering equipment on some circuit of the transformer station abnormally runs, the electric energy balance curve hops. Therefore, whether the electric energy metering equipment of the converting station abnormally runs or not can be accurately judged by monitoring the electric energy balance curve and the abnormity is disposed timely.

Description

technical field [0001] The invention relates to the field of substations, especially a monitoring system for realizing the balance of electric energy in substations. The public mobile communication network is used as the main communication carrier, and wireless, public telephone network, optical fiber network, and small wireless are used as auxiliary communication carriers. Realize the data communication between the system master station and the concentrator, between the concentrator and the collection terminal, and have the function of power balance analysis. Background technique [0002] The substations (stations) invested and built today are generally integrated automation substations (stations) or unattended substations (stations). Most of these substations (stations) are currently equipped with electric energy data acquisition devices, and the collected data are generally sent to dispatch center. Although this type of substation (station) has the function of automatic ...
