In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Example one
Referring to fig. 1, a method for evaluating a nuclear power plant according to an embodiment of the present disclosure is described below, where the method includes:
and S101, acquiring a target maintenance plan by a plan making tool.
In step S101, the target maintenance plan is a plan made by the user based on the maintenance activities. And (4) making a target maintenance plan in the plan making tool by the user, and obtaining the target maintenance plan by the plan making tool after the making is completed. The target repair plan may include a name of the target repair activity, a description of the target repair activity, a start-stop time of the target repair activity, and target unavailable information. It should be appreciated that at least one repair activity may be included in the target repair plan. For the number of the maintenance activities included in the target maintenance plan, the user may select the number according to the actual situation, which is not limited herein.
In some embodiments, the method further comprises: the target tool determines target unavailable information according to the original information of the target maintenance activities, wherein the target maintenance activities are maintenance activities included in the target maintenance plan; accordingly, the planning tool obtains a target maintenance plan, including: and the planning tool acquires the target unavailable information through the second data interface and receives a target maintenance plan which is planned by the user according to the target unavailable information.
In the related art, target unavailable information caused by target maintenance activities is generally identified by professionals, and then manually introduced into a planning tool and a risk assessment tool by the professionals. The process needs manual identification and manual leading-in, has multiple steps, needs professional personnel to complete, and can not be completed by common power plant workers.
Thus, in this embodiment, the target unavailable information is determined from the raw information of the target repair activity using the target tool. The planning tool then retrieves the target unavailable information via the second data interface (as shown in FIG. 2). And finally, the user formulates a target maintenance plan according to the target unavailable information.
The original information of the target maintenance activity includes the name of the target maintenance activity, the description of the target maintenance activity, and the like. The target unavailable information refers to Structure System and Component (SSC) unavailable information caused by target repair activities.
In this embodiment, the target tool can automatically determine the unavailable information of the target, and then the planning tool acquires the unavailable information of the target through the second data interface, so that the professional is not required to determine the unavailable information of the target, the professional is not required to guide the planning tool and the risk evaluation tool, simplicity and convenience are realized, and common power plant workers can also finish the operation.
In some possible implementations, the target tools include an identification sub-tool and a management sub-tool; correspondingly, the target tool obtains target unavailable information according to the original information of the target maintenance activity, and the method comprises the following steps: the identification sub-tool acquires original information of the target maintenance activity and searches a target identification code corresponding to the original information; if the target identification code exists, the identifying sub-tool searches for target unavailable information corresponding to the target identification code, and sends the target unavailable information to the managing sub-tool through a third data interface; the administrative sub-tool sends the target unavailable information to the planning tool through the second data interface.
In the implementation mode, the target identification code is set, and then the target maintenance activities and the target unavailable information are stored through the target identification code. When the identifying tool obtains the original information of the target maintenance activity, the identifying tool searches the target identification code corresponding to the original information, so that the target unavailable information corresponding to the target maintenance activity can be found, and the original information does not need to be analyzed each time to obtain the target unavailable information, so that the target unavailable information can be obtained more conveniently and rapidly.
And after the identification sub-tool acquires the target unavailable information, the target unavailable information is sent to the management sub-tool through the third data interface. The administrative sub-tool, in turn, sends the target unavailable information to the planning tool (as shown in fig. 3) via the second data interface.
The identification sub-tool is a Data system of the power plant, and the management sub-tool can be an SAP (systems Application product Data processing) system. In the related art, the data system of the power plant cannot perform data interaction with the SAP system. In the implementation mode, a third data interface is arranged to connect the data system with the SAP system, so that the data system of the power plant can send target unavailable information to the SAP system.
In other possible implementation manners, the recognition sub-tool may only search the target identification code corresponding to the original information, and then send the target identification code to the management sub-tool through the third data interface. And then the management sub-tool searches for target unavailable information corresponding to the target identification code and sends the target unavailable information to the plan making tool through a second data interface.
In other possible implementation manners, if the target identification code does not exist, the recognition sub-tool analyzes the original information to obtain the target unavailable information. The process of analyzing the original information by the identifier tool is as follows:
after the identification widget obtains the raw information, the identification widget first determines whether the system corresponding to the target maintenance activity has a corresponding PSA model according to the raw information. If there is no corresponding PSA model, the recognition sub-tool does not determine target unavailable information from the raw information. If the system has a corresponding PSA model present, the identifier utility then determines the tagged devices in the system.
The identification widget then determines whether the marked device has a corresponding PSA model. After the marked device with the PSA model is found, the identifying tool searches the marked device with the PSA model for the target device corresponding to the target maintenance activity. And finally, searching for target unavailable information corresponding to the target equipment for maintenance by the identification sub-tool.
If the marked equipment can not be found in the system, or the corresponding PSA model can not exist in the marked equipment, or the target equipment corresponding to the target maintenance activity can not be found in the marked equipment in which the PSA model exists, the manual intervention is carried out.
In this implementation, the correspondence between the tagged device in which the PSA model exists and the target unavailable information, which is the unavailable information corresponding to the tagged device in which the PSA model exists, is stored. Then after the identification sub-tool acquires the target maintenance activity, the identification sub-tool screens out target equipment corresponding to the target maintenance activity on marked equipment with a PSA model step by step, and finally searches for target unavailable information corresponding to the target equipment, so that the target unavailable information can be accurately and quickly acquired.
After the identification sub-tool obtains the target unavailable information, the identification sub-tool stores the target unavailable information and the target identification code in an associated mode, and sends the target unavailable information to the management sub-tool through the third data interface.
And S102, the plan making tool sends the target maintenance plan to the risk evaluation tool through the first data interface so as to instruct the risk evaluation tool to carry out risk evaluation on the target maintenance plan and obtain a target evaluation result.
In step S102, a risk assessment tool may be launched by the planning tool. After the plan making tool obtains the target maintenance plan, the plan making tool sends the target maintenance plan to the risk evaluation tool through the first data interface, and therefore the risk evaluation tool is instructed to conduct risk evaluation on the target maintenance plan, and a target evaluation result is obtained. The risk evaluation tool may transmit the target evaluation result to the planning tool through the first data interface, and the planning tool may display the target evaluation result (see fig. 4).
In some embodiments, the target evaluation result includes a prompt for instructing the user to adjust the target maintenance plan.
In the related art, the target evaluation result does not include prompt information, when the target evaluation result is unacceptable, a worker is required to adjust the target maintenance plan according to experience every time, and then risk evaluation is performed again, so that time and labor are wasted, and the efficiency is low. In this embodiment, the target evaluation result may include not only the instantaneous risk, the cumulative risk, and the risk level of the configuration (the configuration refers to a specific unit state formed by the specific conditions of each system and equipment of the nuclear power plant at the same time), but also prompt information. When the staff judges that the target evaluation result is unacceptable, the staff can adjust the target maintenance plan according to the prompt information, so that the risk evaluation efficiency is improved.
For example, when 8 target repair activities are included in the target repair plan and 2 of the target repair activities may not be performed simultaneously with the other 6 target repair activities, the risk assessment tool may prompt the worker in the target assessment result to stagger the 2 target repair activities from the other 6 target repair activities in the target repair plan.
In addition, the target evaluation result may further include a risk curve, and the risk curve is associated with the target maintenance activities, so that the staff may quickly identify the target maintenance activities and the combination of the target maintenance activities corresponding to the medium-high risk configuration.
In this embodiment, the risk evaluation tool may perform quantitative analysis on the target maintenance plan (to obtain the risk levels of the instantaneous risk, the accumulated risk, and the configuration), and may perform qualitative analysis on the target maintenance plan to obtain the prompt information, so that the user may adjust the target maintenance plan according to the prompt information, and further improve the risk evaluation efficiency of the target maintenance plan.
In other embodiments, the risk evaluation tool performs risk evaluation on the target maintenance plan to obtain a target evaluation result, including: determining a target basic event by a risk evaluation tool, wherein the target basic event is a basic event corresponding to target unavailable information in a target maintenance plan; the risk evaluation tool searches an original minimum cut set corresponding to the target basic event and eliminates the target basic event from the original minimum cut set to obtain a first target minimum cut set; the risk evaluation tool absorbs and/or merges the minimum cut sets in the first target minimum cut set to obtain a second target minimum cut set; and the risk evaluation tool carries out risk evaluation on the target maintenance plan according to the second target minimum cut set to obtain a target evaluation result.
When the risk evaluation tool carries out risk evaluation, the risk evaluation tool needs to re-analyze the fault tree and the event tree every time to obtain a new minimum cut set, and then a target evaluation result is obtained according to the new minimum cut set. The fault tree and the event tree need to be re-analyzed each time, which is troublesome and consumes much time.
In this embodiment, all the minimal cut sets of the fault tree are stored first. Then after the risk evaluation tool acquires the target maintenance plan, the risk evaluation tool firstly determines a target basic event corresponding to the target unavailable information in the target maintenance plan and searches an original minimum cut set corresponding to the target basic event.
Then, the risk evaluation tool removes the target basic event from the original minimum cut set to obtain a first target minimum cut set. And then the risk evaluation tool absorbs and/or merges the minimal cut sets in the first target minimal cut set to obtain a second target minimal cut set. And finally, the risk evaluation tool acquires the probability value of each basic event in the second target minimum cut set from the database, and then carries out risk evaluation on the target maintenance plan according to the probability value of each basic event in the second target minimum cut set to obtain a target evaluation result.
The target basic event is a bottom event in the fault tree, and the occurrence reason of the bottom event does not need to be ascertained. The minimum cut-set refers to a cut-set where the number of bottom events can no longer be reduced, the minimum cut-set reflecting the failure mode of the system. The fault tree refers to a tree logic diagram formed by connecting top events, middle events and bottom events according to a certain causal relationship by using corresponding event symbols, logic gate symbols and transition symbols.
The original minimal cut set corresponding to the target basic event refers to a set including a minimal cut set of the target basic event, or refers to a set including both a minimal cut set with the target basic event and a minimal cut set without the target basic event, and each minimal cut set in the set includes the same number of basic events.
For example, when the target basic events corresponding to the target unavailable information are C1-C4 and the original minimal cut set corresponding to the target basic events C1-C4 is shown as 501 in fig. 5 (at this time, the original minimal cut set includes minimal cut set 1, minimal cut set 2, minimal cut set 3, and minimal cut set 4), the target basic events C1-C4 are removed from the original minimal cut set to obtain a first target minimal cut set, and the first target minimal cut set is shown as 502 in fig. 5. At this time, since the minimal cut set 1, the minimal cut set 2, the minimal cut set 3, and the minimal cut set 4 in the first target minimal cut set are the same minimal cut set, the minimal cut set 1, the minimal cut set 2, the minimal cut set 3, and the minimal cut set 4 in the first target minimal cut set are merged to obtain a second target minimal cut set.
Or, when the target basic event corresponding to the target unavailable information is C and the original minimal cut set corresponding to the target basic event C is shown as 601 in fig. 6 (at this time, the original minimal cut set includes the minimal cut set 11, the minimal cut set 12, the minimal cut set 13, and the minimal cut set 14), the target basic event C is removed from the original minimal cut set to obtain a first target minimal cut set, and the first target minimal cut set is shown as 602 in fig. 6. At this time, since the minimal cut sets 12, 13, and 14 in the first target minimal cut set are not already minimal cut sets, the minimal cut sets 12, 13, and 14 in the first target minimal cut set are absorbed to obtain the second target minimal cut set.
It should be noted that, in the process of absorbing and/or merging the minimum cut sets in the first target minimum cut set, a Hash Algorithm (Hash Algorithm) may be used to accelerate the speed of absorbing and merging, so as to further improve the efficiency of risk evaluation. Or when the risk evaluation is needed by a plurality of target maintenance plans, the risk evaluation is carried out on the plurality of target maintenance plans by adopting multithreading, so that the efficiency of the risk evaluation is further improved.
In this embodiment, all the minimal cut sets of the fault tree are stored first. After the risk evaluation tool determines the target basic event, an original minimum cut set corresponding to the target basic event is searched, and the target basic event is removed from the original minimum cut set to obtain a first target minimum cut set. And the risk evaluation tool absorbs and/or merges the minimum cut sets in the first target minimum cut set to obtain a second target minimum cut set. Therefore, the second target minimal cut set can be obtained without re-analyzing the fault tree and the event tree every time, and the target evaluation result can be obtained more quickly.
To sum up, the application provides an evaluation method of a nuclear power plant, and first, a plan making tool obtains a target maintenance plan. And then the plan making tool sends the target maintenance plan to a risk evaluation tool through a first data interface so as to instruct the risk evaluation tool to carry out risk evaluation on the target maintenance plan and obtain a target evaluation result. In this application promptly, the plan making tool can be automatically through first data interface with target maintenance plan send to the risk evaluation tool, need not the staff and manually imports the target maintenance plan into the risk evaluation tool, and is simple and convenient, has eliminated the data interaction obstacle of plan making tool and risk evaluation tool. And because manual introduction is not needed, errors caused by manual introduction are reduced, and the risk evaluation efficiency is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
