Abstract | The invention discloses a security locking method for relay protection remote concurrency control of a master station and a substation, a multi-scheduling master station operates a relay protection device through substation remote control of a transformer substation, and the substation adopts a concurrency control security locking strategy of single device locking or total station locking which authorizes the remote control authority of the master station. The single-device locking ensures that the remote control operation of the same relay protection device of the transformer substation is only opened to the master station which obtains the remote control operation authorization at the same moment, and the total-station locking ensures that the remote control operation of all relay protection devices of the transformer substation is only opened to the master station which obtains the remote control operation authorization at the same moment. When all levels of dispatching master stations concurrently control |
