The invention discloses a nuclear power plant first-out alarm processing method. The nuclear power plant first-out alarm processing method comprises the following steps that: a parameter acquisition module acquires process parameters in the operation of a nuclear power plant; a safety monitoring module judges whether alarm signals corresponding to the process parameters have been triggered; if the alarm signals have been triggered, the processing module sorts the alarm signals; and a control module determines first-out alarm signals according to the sorting. According to the nuclear power plant first-out alarm processing method of the invention, the process parameters in the operation of the nuclear power plant are acquired, and the alarm signals corresponding to the process parameters are processed, and then, the first-out alarm signals can be determined, and therefore, the accuracy and timeliness of first signal triggering can be realized. The invention also discloses a nuclear power plant first-out alarm processing system.
Description
technical field [0001] The invention belongs to the technical field of nuclear power, and more specifically, the invention relates to a first-out alarm processing method and system of a nuclear power plant. Background technique [0002] The first alarm refers to the first alarm signal that appears when an abnormal accident or failure occurs. This signal is of great significance to the analysis of the cause of the accident. In the protection and control system of nuclear power plants, a large number of automatic protection logics are set up to trigger actions such as protection systems and special safety systems under abnormal conditions to ensure the safety of nuclear power plants. After the protection system and special safety system are activated, the operator of the power plant needs to analyze the fault according to the initial cause of the trigger action. Therefore, the control and protection system of the nuclear power plant should be equipped with a first-out alarm sy...
