大电网安全可靠运行4级梯度预警预控系统设计

在我国现有电网调度管理体制下,电网运行生产过程的4个重要环节(周计划方式分析、日计划方式分析、调度操作前判断、调度运行监控)实质构成了依时间轴逐层逼近电网实际运行状态的递进层次.在此基础上,运用系统工程的思想提出了一种大电网安全稳定运行4级梯度预警预控体系构想.在宏观上,该系统分为电网模型数据采集存储、电网状态建立和电网计算分析及预警预控3个模块.介绍了系统软、硬件设计方案,并对电网模型重建、安全稳定分析、安控系统离线策略在线校核等功能进行了针对性的探讨.该系统为调度运行中实现全过程的预警预控提供了系统化、综合性的解决方案.

Design of four-grade warning and preventive control system for secure and reliable operation of large power grid

There are four important steps of power grid operation under current management system of power grid dispatch in China:weekly planning,daily planning,judgment before dispatch and real-time monitoring,which step-by-step approximates to the actual situation of power grid.With the system engineering concept,a four-grade warning and preventive control system is designed for the secure and reliable operation of large power grid.It is composed of the data collection and storage module,the power system status cons...
