电网自动减载监控管理系统设计

Design of the Monitoring and Management System for Automatic Load Reduction in the Power Grid

为确保电力系统安全稳定运行,低频减载是低频紧急控制最为有效的一种措施,针对低频减载方案制定响应速度慢、编制工作量大、缺乏系统管理的状况,对电网自动低频减载监控管理系统进行了合理设计,以提高省、地、县级调度第三道防线管理水平。采用"基于全网拓扑的电力需求平衡能力在线评估方法",实现低频减载动态监控,通过在线和离线方案策略研究,动态模拟方案执行过程,自动生成模拟分析报告及各种报表,规范专业管理,使工作流程更加顺畅,提高了工作效率,实现电力平衡评估决策的标准化、系统化、条理化和高效化。

The under frequency load shedding is one of the most effective measures to ensure the safe and stable operation of the power system. To address the existing problems such as slow response, a large quantity of work needed, lack of the systematic management in making the under frequency load shedding program, this paper presents a rational and reasonable design of the monitoring and management system for the automatic under frequency load reduction to improve the protection of the province-level, city-level and county-level power dispatching and control. This paper uses ＂an on-line evaluation method based on the network topology of power demand and supply balance＂ to realize the UFLS dynamic monitoring. Through studying the online and offline program strategies, dynamic simulation of the program execution and automatic generation of simulation analysis reports and statements are realized to enable smoother workflow, increase the work efficiency and enhance the professional management.
