The nuclear power station measurement and control device in the embodiment adopts the existing monitoring system of the 500kV switching station of the nuclear power station, so that the mode switching of the reclosing device of the nuclear power station can be remotely controlled through the connection mode between the nuclear power station measurement and control device and the reclosing device. Furthermore, the nuclear power station measurement and control device adopts a dual-network redundant network, namely the nuclear power station measurement and control device comprises a main measurement and control unit and a standby measurement and control unit, wherein the main measurement and control unit is set to be in a network on-line state (possibly becoming an off-network on-line state if faults such as network abnormality occur), and the standby measurement and control unit is set to be in a network standby state, namely the standby measurement and control unit can be adopted when the main measurement and control unit is in the off-network on-line state, so that the mode switching flexibility of the reclosing device can be improved. The nuclear power station reclosing device is used for automatically reclosing a fault tripping switch of the nuclear power station transmission line once when the tripping occurs to the nuclear power station transmission line so as to restore the nuclear power station transmission line to be in long-running state.
As shown in fig. 2, the controller is configured to:
s10: and detecting whether the power transmission line of the nuclear power station trips in real time.
Optionally, whether the power transmission line of the nuclear power station trips or not can be further determined through signals such as current, power and the like of the power transmission line of the nuclear power station; if the current of the power transmission line of the nuclear power station is detected to suddenly change and become zero, the tripping of the power transmission line of the nuclear power station can be judged.
