Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The method for verifying the nuclear security data provided in this embodiment may be applied in an application environment as shown in fig. 1, where a client communicates with a server. Clients include, but are not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server may be implemented by a stand-alone server or a server cluster formed by a plurality of servers.
In one embodiment, as shown in fig. 2, a method for checking nuclear security data is provided, and the method is applied to the server in fig. 1 for illustration, and includes the following steps:
s10, acquiring at least two groups of nuclear safety data from the KNS system.
In this embodiment, the KNS system refers to an offline monitoring system for the status of a power plant. The KNS system collects operation data of a plurality of nuclear power units in a centralized manner through a PI server (a server provided with a PI database, wherein the PI database is a database for industrial data acquisition and storage) arranged in the nuclear power station. The nuclear safety data are operation data which are selected based on operation experience of the nuclear power plant and have high influence on the safety operation importance of the nuclear power unit. The KNS system is provided with a data acquisition interface, and nuclear safety data can be acquired through the data acquisition interface.
The purpose of the verification method for the nuclear safety data provided by the embodiment is not only to monitor the nuclear safety data, but also to analyze the nuclear safety data, so that hidden risks possibly existing in the nuclear power unit can be found. Therefore, at least two groups of core security data are generally required, and the security check of the core security data is realized through the comparison between different groups of core security data. The nuclear safety data comprises a plurality of operation data which are obtained by monitoring at different monitoring points of the nuclear power unit, such as leakage flow of a main pump No. two shaft seals of a nuclear island system of the No. 1 unit, water level reference values of a voltage stabilizer of the nuclear island system, leakage flow of a chemical and volume control system of the No. 1 unit, charging flow of the chemical and volume control system of the No. 1 unit, steam flow of a steam generator of the No. 1 unit and the like. The obtained nuclear safety data can be operation data acquired by the same nuclear power unit at different times, or operation data acquired by different nuclear power units at the same or different times.
S20, acquiring the collection time of the nuclear safety data of each group, and acquiring the working condition information of the nuclear power unit corresponding to the collection time of each group.
In this embodiment, each set of core security data includes a collection time. The corresponding working condition information of the nuclear power units can be the same or different in different collecting time. The working condition information refers to the running working condition of the nuclear power unit. For example, the working condition information before and after the unit power is greatly changed is greatly different (such as the working condition information before and after ELPO (long-term low-power operation)), and the unit is greatly repaired to form the working condition information of the uplink and the downlink (including the working condition information of the downlink thermal shutdown and the working condition information of the uplink thermal shutdown).
S30, determining a verification rule of the nuclear safety data according to the working condition information.
In this embodiment, the verification rules of the corresponding nuclear security data are different according to different working condition information. The check rule not only comprises a check rule of a single group of nuclear safety data, but also comprises check rules among different groups of nuclear safety data. The verification rule is formed based on a combination of theoretical calculation and historical operation experience. The verification rule may be updated based on new verification results obtained from the verification of the historical nuclear security data.
And S40, checking the at least two groups of nuclear safety data according to the checking rule, and generating a checking result.
In this embodiment, the verification rule obtained in step S30 may be used to verify the corresponding core security data, and obtain a verification result. When checking, each piece of nuclear safety data needs to be checked one by one, and the risk level of the nuclear safety data is judged to form a checking result. In some cases, the verification result contains a portion of the core security data marked as normal (i.e., normal data) and another portion of the core security data marked as abnormal (i.e., abnormal data). In addition, for the nuclear security data marked as abnormal, a new risk level may be classified according to the degree to which the data deviates from the check rule.
Optionally, as shown in fig. 3, step S10 includes:
s101, receiving a first input instruction, and acquiring first nuclear safety data from the KNS system according to the first input instruction;
s102, receiving a second input instruction, and acquiring second nuclear safety data from the KNS according to the second input instruction.
In this embodiment, the method for verifying the core security data may be implemented in the form of an application program. In the application program, a plurality of input buttons (buttons on the user operation interface) for inputting the nuclear security data may be provided. The staff member can generate corresponding input instructions through the input buttons and import the nuclear safety data. For example, a first input button provided in the application program for generating a first input instruction and importing first nuclear security data; and the first input button is used for generating a first input instruction and importing first nuclear safety data. The first nuclear security data (refer to the nuclear security data imported through the first input button, and the like), the second nuclear security data, the third nuclear security data, and the like can be classified according to the input buttons.
Here, two or more sets of the nuclear security data may be input according to the application settings. For example, the first nuclear security data may be data collected by a unit at a first time, and the second nuclear security data may be data collected by the unit at a second time. The first time and the second time are different.
Optionally, as shown in fig. 4, step S30 includes:
s301, when the first nuclear safety data are collected when the nuclear power unit is in a first working condition, acquiring a first check rule corresponding to the first working condition, wherein the first check rule is used for checking the first nuclear safety data;
s302, when the second nuclear safety data are collected when the nuclear power unit is in a second working condition, acquiring a second check rule corresponding to the second working condition, wherein the second check rule is used for checking the second nuclear safety data;
s303, acquiring a combination verification rule according to the first working condition and the second working condition, wherein the combination verification rule is used for verifying the difference value between the first nuclear safety data and the second nuclear safety data.
In this embodiment, the verification rules under different working conditions are generally different. The verification rule comprises a group of nuclear safety data used for independently verifying a certain working condition, and two or more groups of nuclear safety data used for verifying different working conditions or the same working condition. For example, under the first working condition, the first check rule sets a preset value range of the nuclear safety data a (belonging to the first nuclear safety data) to be [0,1]; under the second working condition, the second check rule sets the preset numerical range of the nuclear safety data A (belonging to the second nuclear safety data) as [2,3]; and the combination check rule sets a preset numerical range of the difference value between the nuclear safety data A under the first working condition and the nuclear safety data A under the second working condition to be [1,2.5].
Optionally, as shown in fig. 5, step S40 includes:
s401, judging whether the first nuclear safety data is in a first preset numerical range specified by the first check rule; if yes, judging that the first nuclear safety data is normal data; if not, marking the first nuclear safety data as abnormal data;
s402, judging whether the second nuclear safety data is in a second preset numerical range specified by the second check rule; if yes, judging that the second nuclear safety data is normal data; if not, marking the second nuclear safety data as abnormal data;
s403, judging whether the difference value between the first nuclear safety data and the second nuclear safety data is in a difference value range specified by the combined check rule; if yes, marking the first nuclear safety data and the second nuclear safety data as normal data; if not, judging that the first nuclear safety data and the second nuclear safety data are abnormal data.
In this embodiment, if the core security data (including the first core security data and the second core security data) and the difference value obtained based on the core security data (such as the difference value between the first core security data and the second core security data) are within the corresponding numerical range, it is determined that the core security data is normal data; if the data is not in the corresponding numerical range, the data is judged to be abnormal data. Specifically, the normal data may be identified in a first color, data in which an abnormality occurs once (e.g., the first nuclear safety data is in a first preset numerical range specified by a first check rule, but the difference between the first nuclear safety data and the second nuclear safety data is not in a difference numerical range specified by a combination check rule) may be identified in a second color, and data in which an abnormality occurs twice (e.g., the second nuclear safety data is not in a second preset numerical range specified by a second check rule, and the difference between the first nuclear safety data and the second nuclear safety data is not in a difference numerical range specified by a combination check rule) may be identified in a third color. For example, the first color may be green, the second color may be yellow, and the third color may be red. It should be noted that steps S401-S403 are independent determination processes, and each verification of the core security data is performed twice (when the third core security data exists, a pairwise comparison mode may be still adopted), and the result of each verification is independent. The final verification result is superposition of the results after multiple verification.
Optionally, as shown in fig. 6, step S10 includes:
s103, acquiring a plurality of groups of nuclear safety data from the KNS system according to a preset acquisition period;
s104, selecting the at least two groups of nuclear safety data from the plurality of groups of nuclear safety data according to a preset selection rule.
In this embodiment, the preset acquisition period may be set according to actual needs. For example, it may be set three times per day. In a primary acquisition process, multiple groups of nuclear safety data can be acquired from the KNS system, and each group of nuclear safety data refers to operation data of one nuclear power unit. After the acquisition is completed, the nuclear safety data can be stored in a database on a local disk or a cloud server. It should be noted that the multiple sets of nuclear safety data referred to herein include both currently acquired nuclear safety data and previously acquired (several times before) nuclear safety data.
The preset selection rule can be set according to actual needs, for example, the preset selection rule can be set as follows: and selecting the nuclear safety data of the first nuclear power unit at the first moment of the first day as first nuclear safety data, and selecting the nuclear safety data of the first nuclear power unit at the first moment of the second day as second nuclear safety data. The preset selection rule may also refer to a manually entered setting.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present application.
