The invention relates to an operation monitoring system of a main pump of a nuclear power plant. The operation monitoring system comprises a central processing module, an acquisition module and a parameter display module, wherein the acquisition module is used for reading operation monitoring parameters of the main pump, the central processing unit is used for receiving and processing the operation monitoring parameters and sending the operation monitoring parameters to the parameter display module, and the parameter display module is used for displaying the processed operation monitoring parameters and comprises a first state region, a second state region and a third state region. The operation monitoring system of the main pump of the nuclear power plant is in strict accordance with therequirements on the monitoring of the main pump, carries out the centralized distribution of the operation monitoring parameters, collects information and execution means required by an operator for program execution, makes full use of the characteristic of real-time state display of DSC, greatly facilitates the control of related equipment according to the state displayed and ensures the safety.The system takes the characteristic of man-machine integration into full consideration and provides reliable redundancy judgment means and effective defense in depth.
Description
technical field [0001] The invention relates to an operation monitoring system, in particular to a nuclear power plant main pump operation monitoring system. Background technique [0002] The main pump is the most important rotating equipment in the nuclear power plant, which provides the forced circulation head of the coolant in the primary circuit and takes out the heat of the reactor. [0003] The main pump needs to monitor each process equipment to determine whether the main pump is in the condition of starting and running. In addition, when the main pump is running, by monitoring the operating parameters of the main pump, abnormalities in the operation of the main pump can be found, and according to the pump stop standard, the main pump will be shut down urgently when the parameters exceed the operating standard. [0004] In the simulated main control room environment, the main pump monitoring method is to check all these parameters one by one through the operation pro...
