随着变电站综合自动化水平的提高,远方遥控的对象从断路器扩展到了隔离开关和接地开关,隔离开关和接地开关的动作往往要受较复杂的五防规则的限制。在500kV湖州含山变电站中,开发了一套遥控闭锁软件,将五防判断功能以遥控闭锁软件的形式整合进后台系统。遥控闭锁软件预先将操作闭锁逻辑存入数据库,当对设备进行遥控时,从数据库中取出此设备的操作闭锁逻辑进行判断,逻辑满足则允许下发遥控命令,反之则不允许。遥控闭锁软件的成功应用为将来简化变电站后台系统配置进行了有益的尝试。
With the improvement of substation automation level, the object of remote control is extended from the circuit breaker to the isolation switch and the grounding switch. The actions of the isolation switch and the grounding switch are often limited by more complex five-prevention rules. In 500kV Huzhou Hanshan substation, developed a set of remote control locking software, will be five anti-judge function to remote control software in the form of integration into the background system. The remote control lockout software stores the operation lockout logic into the database in advance. When the device is remote-controlled, the operation lockout logic of the device is taken out of the database to be judged. When the logic satisfies, the remote control command is allowed, otherwise, the lockout is not allowed. The successful application of remote lockout software is a useful attempt to simplify the substation back-end system configuration in the future.
