Embodiment Construction

[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] 1. Verified content

[0033] The verification of the digital alarm procedure includes the correctness verification of the content of the alarm procedure, the correctness verification of the digital design of the alarm procedure and other verifications, including:

[0034] 1. Verification of the correctness of the content of the alarm procedure: Due to the large number of systems included in the alarm procedure, the preparation time of the alarm procedure and the experience level of the compiler are uneven, etc., the content of the alarm procedure may still use the traditional board design, or the content description is as room The number, etc. do not match the latest design of the power plant, and whether the alarm can be effectively handled through operator intervention after the alarm is triggered is verified in...

Abstract

The invention provides a nuclear power plant digital alarm procedure verification method comprising the following steps that firstly, initial condition setting is performed, i.e. the initial working condition of alarm to be verified is set; then an alarm trigger method is selected to trigger alarm; then initial inspection is performed, i.e. an operator inspects alarm information from an alarm window via introducing fault trigger alarm under the initial effective working condition; then an optimized logic signal is triggered firstly if alarm of the optimized logic signal exists; and finally alarm verification is completed. The verification method is used for verification of correctness and rationality of the alarm procedures, verification of correctness and rationality of the alarm procedure digital design and verification of consistency of alarm window display information and alarm card information so that correctness and rationality of alarm procedure compiling and the digital alarm procedure design can be ensured, and thus the requirements of nuclear power plant safety operation can be met.

Description

technical field [0001] The invention belongs to the control technology of a main control room of a nuclear power plant, and in particular relates to a verification method of a digital alarm procedure of a nuclear power plant. Background technique [0002] With the progress and development of computer technology, most new nuclear power plants use DCS system. In order to make full use of the advantages of computer processing information and enable the operators in the main control room to flexibly deal with various faults in the power station, the digital alarm function is also integrated into the DCS system. In recent years, nuclear power units independently designed and built in my country have also begun to adopt digital alarm procedures to improve the safety, reliability and economy of the units. In order to ensure the correctness of the design of digital procedures, the digital verification of alarm procedures has become an indispensable work. However, due to the innova...
