Embodiment 1

[0053] The embodiment of the present invention provides an abnormal detection system for DCS operation log of nuclear power plant, with figure 1 It is a structural schematic diagram of the abnormal detection system of the present invention, including a DCS data acquisition system, and the DCS data acquisition system involves a DCS system and a KNS system (nuclear power plant real-time information monitoring system) 100, wherein:

[0054] KNS system 100, connected to the DCS system, is used to establish a real-time and historical database platform for the production process of the whole plant, collect production data of the whole plant, and realize centralized storage, management and application of production data in the whole plant;

[0055] The DCS data source module 200 is connected with the KNS system 100 and is used for collecting real-time and historical operation data of the KNS system 100 and storing the DCS operation log library of the KNS system 100 . Specifically, th...

Embodiment 2

[0091] The implementation of the present invention provides a method for abnormality detection of a DCS operation log of a nuclear power plant, which is applicable to the abnormality detection system of the DCS operation log of a nuclear power plant shown in Embodiment 1, see Figure 5 , the method includes the following steps:

[0092] S1. Collect real-time and historical operation data of the DCS database system, and store the DCS operation log library of the DCS database system;

[0093] S2. Download the DCS operation document information from the DCS database system. The operation document information includes an operation procedure document and an alarm document. According to the association between the operation procedure document and the alarm document, a standard operation procedure is established and generated as a detection basis;

[0094] See attached Image 6 , the step S2 further includes the following steps:

[0095] S21. Download the operating procedure docume...

Abstract

The invention provides an abnormal detection system and a method for an operating log of a nuclear power plant DCS. The method comprises the following steps: collecting real-time and historical operation data of a DCS database system; storing a DCS operation log library; downloading a DCS operation procedure document and an alarm document; establishing a standard operation procedure according to the association between the operating procedure document and the alarm document; establishing a standard operation state model according to the historical operation data; receiving current operation state data in real time and determining whether the current operation data is abnormal; extracting an operation log corresponding to the abnormal state from the operation log library after confirming atime entry and a system scope according to an abnormal state signal; comparing with the extracted operation log according to a detection basis; determining whether the operation log is consistent withthe standard operation procedure; and reporting an abnormal detection result hierarchically. The abnormal detection system for the operation log of the nuclear power plant DCS has the beneficial effects that the operation log of the DCS is effectively detected, the operational risk caused by the misoperation is found in time, and the operation safety of the nuclear power plant is improved.

Description

technical field [0001] The invention relates to the technical field of electronic data of nuclear power plants, in particular to a system and method for abnormality detection of DCS operation logs of nuclear power plants. Background technique [0002] The main function of the nuclear power plant real-time information monitoring system (KNS system) is to establish a real-time and historical database platform for the production process of the whole plant, collect the production data of the whole plant, and realize the centralized storage, management and application of the production data in the whole plant. Technical support and other production supervisors provide an information system for monitoring the production process of the whole plant and comprehensive optimization services. [0003] Nuclear power plants currently use functions such as KNS system-based history playback, log query, digital procedures, and alarm cards, which can detect abnormal operations through manual ...
