基于拓扑结构的变电站网络型防误闭锁系统研究

摘要

The problems existing in traditional three anti⁃misoperation locking systems of mechanical type,electrical type and microcomputer type are analyzed. For the above problems,the advanced network technology used to design the networked anti⁃misoperation locking system scheme for the substation based on topology structure is proposed. The identification method and locking mode of the network topology structure for the substation are determined. And then the hardware and software of this new anti⁃misoperation locking system are respectively introduced in detail. The networked anti⁃misoperation locking system for the substation based on topology structure can solve the problems existing in traditional anti⁃misoperation locking systems,and is easy to realize automation. The system has a practical guiding significance.%在分析了传统的机械式、电气式和微机式三种防误闭锁系统存在的问题的基础上，提出了利用发达的网络技术，设计基于拓扑结构的变电站网络型防误闭锁系统方案，首先确定了变电站网络拓扑结构的识别方法和闭锁方式，然后分别对该新型防误闭锁系统的硬件和软件加以详细介绍，基于拓扑结构的变电站网络型防误闭锁系统不仅解决了传统防误闭锁系统存在的问题，而且易于实现自动化，具有实际的指导意义。
