摘要
电力监控系统的可靠性是电网安全运行的保证,很多企业对此进行了长期研究,并提出了一些方案。最常见方案是双服务器、双前置机、多值班员机的可靠冗余运行配置。由于服务器和前置机是系统的关键设备,如果它们出现单机运行状况,则不能满足安全运行要求。该文主要描述了在双服务器、双前置机的可靠冗余配置基础上,进行服务器和前置机的多重可靠冗余的设计与实现方案。该方案已在全国多个集控中心和调度中心监控系统中实现。
The reliability of supervisory and control system guarantees the power network secure operation. Many vendors have researched reliability for a long time and put forward various solutions. Dual servers, dual communication controllers and multiple LMIs redundant configuration arc the common solution. As servers and communication computers arc key equipments, they cannot meet secure operation needs if they work alone. Based on dual servers, dual communication controllers redundant configuration, the paper mainly deals with the design and implementation of multi-layered reliable redundance. This solution has been already used in many Integrated Control Centers and Dispatching Centers.
