Measurement system for action response time of DCS control station of nuclear power plant

Abstract

The invention belongs to the technical field of nuclear power plant automatic control systems, and particularly relates to a nuclear power plant DCS control station action response time measuring system which realizes automatic response time measurement through a time synchronization module, a signal output module and a high-speed switching value acquisition module. Through the intelligent modes of establishing an engineer station maintenance interface, a special test script, one-button guide operation and the like, the working efficiency of DCS response time measurement is improved, the working pressure of personnel is reduced, and the method can be used for motion response time measurement of the DCS.

Description

technical field

[0001] The application belongs to the technical field of automatic control systems of nuclear power plants, and in particular relates to an action response time measurement system for DCS control stations of nuclear power plants. Background technique

[0002] The reactor protection system of a nuclear power plant monitors important parameters related to reactor safety, and when these parameters reach or exceed the setting values ​​determined by safety analysis, it generates the necessary control signals to trigger emergency shutdown and the actions of special safety devices and related supporting system equipment , to prevent the state of the reactor from exceeding specified safety limits, or to mitigate the consequences of accidents in which safety limits are exceeded. The important parameters detected by the reactor protection system and their protection action setting values ​​are determined by safety analysis. When determining the protection action settin...

Embodiment Construction

[0046]In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, not all of them. Based on the embodiments described in this application, all other embodiments obtained by those skilled in the art without creative efforts are within the protection scope of this application.

[0047] At present, nuclear power plants usually adopt the strategy of increasing staff and three shifts for response time measurement to ensure that the duration of reactor protection response time measurement work is controlled within 7*24h, so as to avoid affecting the critical path of nuclear power plant overhaul, and the work pressure of personnel is high , Low work efficie...
