Abstract
The utility model belongs to a nuclear power plant instrument control technology, and specifically discloses a main pump control and protection system. The system comprises a human-computer interface unit, a communication unit connected with the human-computer interface unit, and a processing unit connected with the communication unit, and also comprises a data acquisition unit and a driving unit. The processing unit comprises a constant value comparison module, a control module, and a diagnosis module. The constant value comparison module processes data transmitted by the acquisition unit, and then respectively transmits constant value comparison results to the control module and the diagnosis module. According to parameters of each component of a main pump acquired by the data acquisition unit, the human-computer interface unit sends start and stop instructions to control operation of the main pump and auxiliary equipment. If faults occur, alarm indication can be given out. Therefore, the system simplifies control of the main pump and the auxiliary equipment thereof, and operators can rapidly find out a fault point through a fault diagnosis function and remove the faults, so that normal operation of the main pump during the nuclear power plant is operating is ensured, thereby ensuring safe and stable operation of the nuclear power plant.
