变电站程序化操作的探索与实践

讨论了建设程序化操作变电站的基本条件和变电站自动化系统间隔层完成本间隔操作、站控层实现跨间隔操作的技术方案。分析了程序化操作过程中的安全保证机制,提出了在变电站自动化系统中保障操作安全的主要判别依据。关于全变电站范围程序化操作、程序化操作过程中需改变继电保护设备运行方式以及厂站与控制中心间通信规约的限制问题给出了建议。采用智能化的高压电气设备和控制系统及改进变电站运行操作方式是适应电力建设发展的需求。

Research and practice of sequential operation in substation

Basic conditions for the sequential operation of substation are discussed,and a tech-nical plan is presented for substation automation system to realize cell operation at cell level and cross-cell operation at station control level.The safety mechanism in sequential operation process is analyzed,and the main criteria for ensuring operational safety are put forward.Suggestions are given for the sequential operation of whole substation,the change of protection operation mode during sequential operation and the restriction in communication protocol between substation and control centre.The intelligent HV electrical equipment and control system and the improvement of operation mode of substation are required for the development of electrical network.
