电力系统实时监控设计

摘 要

随着我国电力系统网络大规模改造,电网的规模飞速发展,对整个供电过程进行有效的实时监控,是保证供电可靠性和连续性的重要手段。

本文针对某110KV降压变电站负荷情况以及进、出线数目进行详细分析,根据供电可靠,运行灵活,经济性好的要求,确定其电气主接线方案。在此基础上,利用目前国内流行的力控组态软件,主要设计了一个110KV变电站实时监控平台,实现“四遥”(遥测、遥信、遥调、遥控),实现曲线自动生成,以及实时数据显示、历史数据查询、报警记录功能等。

Design of power system real-time monitoring

Abstract

With large-scale transformation of China's electric power system network, power grids, the size of the rapid development of the whole supply process for effective real-time monitoring is to ensure supply reliability and continuity of an important means.

In this paper, a 110KV substation step-down load as well as into, a detailed analysis of the number of outlet, according to supply reliable, flexible operation and a good economy requirements, determine the main electrical wiring program. On this basis, using the strength of the domestic epidemic control configuration software, the main design of a 110KV substation real-time monitoring platform, achieving \, remote, remote adjustment, remote control), and curve automatically generated, and real-time data, historical data query, alarm recording functions.

Key words: Power system; power control5.0; substation; real-time monitoring
