调度控制中心功能的发展——电网实时安全预警系统

提出了电网实时安全预警系统的可行方案,给出了其基本原理和主要特征,设计了其功能框架和体系结构.该系统在实时信息重建的基础上,利用并行和分布式计算技术,从多个侧面对电网实施"分诊",自动跟踪和确定电网实时安全级别,快速找出各类安全隐患,然后通过"会诊",实时给出综合安全预警报告,展示给调度员.设计了系统的实时性指标.基于IEC 61970标准化技术,可方便地实现与不同调度控制中心现有系统的集成.通过该系统的研发和实施,可以大幅度提高电网实时安全预警能力.

EVOLUTION OF THE POWER DISPATCHING CONTROL CENTER --REAL TIME POWER SECURITY EARLY WARNING SYSTEM

A real time power security early warning system (RTPSEWS) is presented to significantly improve the ability of real time power security early warning as a new function of the modern power dispatching control center. The principle, features, functional framework, system configuration and performance index of the RTPSEWS are given. In the RTPSEWS, firstly a real time information rebuilding is carried out to improve the reliability of the RTPSEWS, secondly multiple diagnoses on the security of the power system are reported to the dispatchers by subsystems in parallel, thirdly, a consultation is held to give a comprehensive early warning report on the security of the power system under real time environment. Based on the standard IEC 61970 control center application programming interface (CCAPI), the RTPSEWS can be conveniently integrated with existing information systems installed in the power dispatching control centers.
