摘要:

为了解决目前智能变电站中变压器保护装置存在速动性和可靠性不足的问题,提出了一种全主分布式就地化变压器保护实现方案,在变压器各侧开关安装保护子机,子机之间通过内部高速环网交互数据,每个子机均配置完整的变压器保护功能,保护动作时直接通过电缆跳开与子机相连的开关,提高保护的速动性。在总体实现方案对比分析的基础上,着重论述了装置三层网络通信机制、远程人机管理等关键技术。

Abstract:

To enhance the speed and reliability of existing intelligent substation transformer protective device, a full master type distributed localized transformer protection plan was introduced. Protection submachine was provided to each side of transformer. Submachines communicated with each other by internal high speed loop network. Each submachine was equipped with full protective function. Switch will be tripped through cable if protection behavior activated. Based on the overall plans comparison, triple layer network communicating mechanism, remote humanmachine interface and other key technologies were discussed.
