一种简单的变电站改造联锁互通代理装置实现方法

The simple implementation method of substation transformation interflowing interlock agent device

IEC 61850的日益普及及稳定运行促进了传统IEC 103站智能化升级改造的需求,改造过程中存在着较长时期新、旧系统并行运行的过渡过程,这期间新、旧系统的测控跨间隔联锁可能存在信号获取不到而导致联锁失败,同样后台监控五防也存在类似跨间隔防误逻辑失败问题。本文在充分分析变电站改造需求的基础上,借鉴已有方案,挖掘问题本质,提出了联锁互通代理装置及其接入方案。此方案与现有代理装置相比,具有功能齐全、方案完备、配置简单、稳定可靠等特点。实践证明本文的方法是有效的。

The increasing popularization and stable operation of IEC61850promote the demand ofintelligent upgrading traditional IEC103stations.There will be a long period of new and old systems running in parallel after starting substation transformation.During this period,there may be interlock information of BCU loss both in the new and old system.Also,monitoring five defense exists the same problem.On the basis of fully analyzing the needs of substation transformation,this paper draws on the existing schemes and excavate the essence of the problem,and puts forward the complete scheme of interlock agent and its accessing method.Compared with the existing agent,it has good characteristics of complete functions,complete scheme,simple configuration,stable and reliable and so on.The actual substation application proves the method is effective.
