Embodiment Construction

[0058] In order to make the purpose, technical solutions and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are only for explaining the present invention, not for limiting the present invention.

[0059] Please refer to figure 1 , figure 1 Provides a nuclear power plant first-out alarm processing method, which specifically includes:

[0060] Step 101: The parameter collection module collects process parameters in the operation of the nuclear power plant.

[0061] Specifically, the collection of process parameters usually involves multiple signal collections, such as the temperature parameter collection of the first loop of the nuclear power plant, and the temperature parameter collection of the three loops. At this time, the collected parameter signa...

Abstract

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 present invention belongs to the technical field of nuclear power. More specifically, the present invention relates to a method and system for processing the first-out alarm 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 the dedicated safety system are activated, plant operators need to analyze the fault based on the initial cause of the trigger action. Therefore, the nuclear power plant control and protection system should be equipped with a first-out alarm system to...
