Embodiment Construction
[0034] In a preferred embodiment of the present invention, the method for automatically calling the pressure-temperature map of a nuclear power plant mainly includes the following steps: receiving request information for calling the pressure-temperature map; judging whether the automatic call condition is satisfied according to the request information; when the automatic call condition is satisfied, The operating state of the main pump is judged, and the corresponding pressure-temperature diagram is automatically selected according to the operating state of the main pump.
[0035] Further, as figure 1 As shown, the specific steps include:
[0036] S101. Receive the request information sent by the user to call the pressure-temperature map (ie, the P-T map);
[0037] S102. Begin to judge whether the current status of the nuclear power plant satisfies the automatic calling condition according to the call request information, that is, whether the unit power of the nuclear power ...

The invention discloses a pressure-temperature chart automatic-calling method and a pressure-temperature chart automatic-calling system for a nuclear power plant. The pressure-temperature chart automatic-calling method for the nuclear power plant mainly comprises the following steps of: receiving pressure-temperature chart calling request information; judging whether automatic calling conditions are met or not according to the request information; and if the automatic calling conditions are met, judging the running state of a main pump and automatically selecting a corresponding pressure-temperature chart according to the running state of the main pump. The pressure-temperature chart automatic-calling system for the nuclear power plant mainly comprises a storage module and an automatic calling module, wherein the storage module is used for storing a plurality of pressure-temperature charts applicable to different working conditions; and the automatic calling module is used for judging whether the automatic calling conditions are met according to a calling request, and automatically calling the pressure-temperature chart according to the working conditions of the power plant if the automatic calling conditions are met. In the method and the system, the pressure-temperature (P-T) chart is rapidly automatically called without manual selection so as to save time and avoid manual errors in judgment.
Description
technical field [0001] The invention relates to the field of nuclear power control, in particular to a method for automatically invoking a pressure-temperature diagram of a nuclear power plant and a system thereof. Background technique [0002] With the application of digital control system (DCS) in nuclear power plants, the degree of automation of nuclear power plants has been greatly improved, and users can monitor and control the entire nuclear power plant in real time in the main control room. According to the needs of nuclear power plant operation, users need to monitor the temperature and pressure of the primary circuit in real time and ensure that the pressure-temperature operating point is in the allowed area. When the pressure-temperature operating point deviates from the operating allowable area, the user needs to perform corresponding operations to bring the operating point back to the operating area; if the primary circuit pressure-temperature operating point dev...
