The experimental premonitory information refers to: some abnormal signs found when the generator is subjected to various tests in the overhaul process (such as measuring the direct current resistance of a stator winding) need to be submitted manually.
Step S102: and analyzing the fault of the generator according to the primary premonitory information to obtain fault information.
The fault symptom refers to primary precursors accessed by the system when the system carries out fault diagnosis on the generator, and the system further determines the fault of the generator through the primary precursors, namely all the diagnosed faults of the system are caused by the primary precursors. It should be noted that the present system may be a software system and/or a hardware system for executing the procedures of the method for diagnosing the generator condition of the million kilowatt class pressurized water reactor nuclear power plant of the present embodiment.
The primary aura is obtained from four parts of a stator winding, a stator iron core, a hydrogen cooler, a rotor and a hydrogen oil-water system. Each part of primary aura is divided into on-line real-time aura, alarm in operation, inspection aura and test aura.
Step S103: and displaying at least one fault tree picture comprising the fault information.
The fault tree reflects the relation between faults and can assist in diagnosis, analysis and prevention of the faults. The fault tree picture is also called a relation graph of the fault tree.
In this embodiment, if it is diagnosed that there is a failure in the stator portion, a failure tree picture of the stator portion may be displayed. Alternatively, there may be multiple fault tree pictures at certain locations of the generator.
In the embodiment of the invention, the accessed primary premonitory information is acquired when the generator is subjected to fault diagnosis; the fault of the generator is analyzed through the primary premonitory symptom information to obtain fault information, at least one fault tree picture including the fault information is displayed, so that the fault information of the generator is visually displayed, a user can directly acquire the state of the generator conveniently, manual secondary judgment and reasoning are not needed, and the generator has high practicability and usability.
Example two
Fig. 2 is a schematic flow chart illustrating an implementation of the method for diagnosing the state of the generator of the million-kilowatt pressurized water reactor nuclear power plant according to the second embodiment of the present invention. As shown the method may comprise the steps of:
step S201: and acquiring accessed primary premonitory information when the generator is subjected to fault diagnosis.
Step S202: and analyzing the fault of the generator according to the primary premonitory information to obtain fault information.
Step S203: and displaying at least one fault tree picture comprising the fault information.
The steps S201 to S203 are the same as the steps S101 to S103, and reference may be specifically made to the related description of the steps S101 to S103, which is not repeated herein.
Optionally, displaying a fault part in the fault tree picture, and listing various faults occurring at the part;
and highlighting various faults occurring at the parts, and displaying the corresponding occurrence times of the faults.
When the equipment is inquired to be abnormal, the fault names list the faults diagnosed when the equipment is abnormal, the relation graph of the fault tree where the current fault is located can be displayed by clicking each fault name, and the fault is displayed in obvious red to remarkably prompt the fault generated by a user.
When the inquiry equipment is abnormal, the button of the fault part is activated, and the button is clicked to enter the inquiry window of the fault part. The generator is divided into seven parts, namely a stator, a rotor, a shell, a hydrogen cooler, a stator inner cooling water system, a hydrogen system and an oil system. The fault part enters the stator part by default, various faults possibly occurring at the part are listed in a fault position diagram, the diagnosed faults are changed into red, the number displayed at the back is the frequency of the faults, whether faults occur at each part of the generator or not, which faults occur or not occur repeatedly, and the degree of the repetition is so that the weak part and frequent faults of the generator can be conveniently known, and scientific basis is provided for formulating specific preventive measures.
Step S204: when a query request of a user is received, at least one fault tree picture comprising fault information corresponding to keywords in the query request is displayed.
Wherein the query request includes a query condition, the query condition including at least one of: generator set number, equipment exception type, equipment exception attribute and equipment exception level.
For example, selecting fault diagnosis, entering an equipment abnormal query window, setting query conditions above the window, and further setting query, fault part, report, export and return function buttons. Different condition combinations can be set for inquiry, which helps users to find the abnormality of the equipment to be found more quickly, and the inquiry result can be generated into a report or exported as an Excel file, thereby facilitating technical management. When the query is finished and the equipment is abnormal, the fault part query button is activated, and can enter a fault part query window to check the fault condition of each part. The following description is provided for the selection of query conditions:
the query conditions are as follows: generator set number, equipment exception type, equipment exception attribute, equipment exception level, query time period and the like. The setting and meaning of the query conditions are described below.
The machine set number is as follows: the number of the unit to be inquired. The number of the inquired unit is the same as that of the operating unit above the page, and the unit to be inquired is selected by switching the operating unit number.
Device exception category: the method comprises three types of steps of waiting for processing, ending and ignoring, and the exception of the equipment to be processed is inquired by default.
Wherein, the treatment: and the device exception which is not finished or ignored and still needs to be processed continuously is ended by the query termination time. According to the personnel identity and the system state required by the treatment, the treatment to be carried out is divided into operation treatment to be carried out and maintenance treatment to be carried out.
And (4) finishing: and completing fault diagnosis in the inquiry time period, wherein the finished equipment is abnormal.
Already ignored: device exceptions that are ignored during the query period.
The device exception attribute can be divided into new generation and past legacy.
Wherein the new occurrence refers to the equipment abnormality newly occurring in the query time period.
Legacy refers to device exceptions that occur before the query start time and that have not been processed.
Optionally, the device abnormality levels include four levels, which are a first level, a second level, a third level and a fourth level, and when it is detected that the device is in the first level, the generator is shut down; when the device is detected to be in the second level, reducing the load of the generator; when the device is detected to be in the third level, reducing the water temperature of the generator; when the device is detected at the fourth level, monitoring is enhanced in operation of the generator.
It can be seen that the first level is the most severe fault, decreasing in sequence, and the fourth level is mild abnormality. The system queries for four levels of device exceptions by default. And when the query is finished and the equipment is abnormal, the query is not carried out according to the grade.
In the embodiment, when a query request of a user is received, at least one fault tree picture including fault information corresponding to a keyword in the query request is displayed, and the corresponding fault tree picture can be displayed according to the query request of the user in a flexible manner; in addition, the equipment abnormity is graded, and processing operation corresponding to the graded grade is provided, so that the equipment abnormity can be processed correspondingly, and the processing efficiency is high.
EXAMPLE III
Fig. 3 is a schematic flow chart illustrating an implementation of the method for diagnosing the state of the generator of the million-kilowatt pressurized water reactor nuclear power plant according to the third embodiment of the present invention. As shown in the figure, the method comprises the following steps:
step S301: acquiring accessed primary premonitory information when the generator is subjected to fault diagnosis;
step S302: analyzing the fault of the generator according to the primary premonitory information to obtain fault information;
step S303: and displaying at least one fault tree picture comprising the fault information.
The steps S301 to S303 are the same as the steps S101 to S103, and reference may be specifically made to the related description of the steps S101 to S103, which is not repeated herein.
Step S304: and diagnosing the fault through a man-machine conversation.
After the query condition is set, a query button is clicked, and all equipment exception lists meeting the query condition are displayed, wherein the equipment exception lists comprise the contents of numbers, the primary time, the primary aura, the current aura, the generation time, the level, the type and the like of the current aura. Clicking a browsing part of a record can open an abnormal processing interface of the equipment, checking the diagnosis opinions of the system, taking relevant countermeasures according to expert suggestions, answering a man-machine conversation according to the checking result, and gradually diagnosing the fault.
Step S305: and judging whether the human-computer conversation has an uncertain problem.
If the human-computer conversation has no uncertain problems, the analysis and the diagnosis are directly carried out.
When the report inquiry equipment is abnormal, the equipment to be processed can be displayed in a report form, and the equipment to be processed appears in a report table in a mode of steps, symptom description, diagnosis opinions and fault trees (expressed in a picture form). After the query is finished, finding the abnormality of the equipment to be processed, clicking the browsing option after the entry, and entering a fault diagnosis browsing window.
Aiming at each step of fault diagnosis, the system gives corresponding diagnosis opinions and corresponding measures, takes corresponding measures according to expert suggestions given by the system, answers human-computer conversation according to the inspection result, further diagnoses the system according to the answer result of the human-computer conversation, and finally finds all existing faults.
The user participates in fault diagnosis through a man-machine session, and it should be noted that the system state and the authority of the operating user are as follows: the operation to be processed is carried out by the operator in the operating state, the operation to be processed is overhauled by the maintainer in the shutdown state, the operator is responsible for the state conversion from the operating state to the shutdown state, and the maintainer is responsible for the state conversion from the shutdown state to the operating state. However, if a user has the authority to perform operation submission and overhaul submission at the same time, the system state does not need to be converted, and the processing can be completed until the user clicks 'transfer' at the transfer node. The main operation content is as follows:
recording the actual processing condition: the examination processing is carried out item by item according to the corresponding measures, and the actual processing situation can be recorded in the 'waiting processing' of each measure for later inquiry (the operation is optional).
Step S306: if there is an indeterminate problem, it is determined whether the indeterminate problem is satisfied.
Step S307: and if the conditions of the uncertain problems are sufficient, reasoning the uncertain problems and displaying a reasoning result in an interface.
For steps S306 and S307, the questions of the human-computer conversation are answered (clicking yes or no in the human-computer conversation column can answer, clicking reset can clear the answer result, the questions which cannot be determined can not be answered), and then clicking the "submit" button submits the result to the inference engine for inference. If the conditions given by the human-machine conversation are sufficient, the inference result will be displayed in a pop-up fault list. It should be noted that there may be several inference results, and a user may select one of them to continue processing, and once a certain result is selected to be viewed, the user must query in the query window to view other results. The inference engine can be a software functional module with an inference function.
While the user may make erroneous decisions for a variety of reasons while conducting the human-computer conversation, the system preferably provides a "backtrack" function that allows the user to backtrack the current inference results and reasone the human-computer conversation again. The current result can be backtracked by clicking a backtracking button on the console. Theoretically, a failure can be traced back to the head, but considering the accuracy of the system, the system imposes limitations on the tracing operation in the following aspects:
A. the first step of failure does not allow backtracking, i.e., a failure cannot be traced all together.
B. Failures that are pushed out by online real-time data cannot be traced back (i.e., failures that are pushed out by human-machine sessions can only be traced back).
C. The conclusions drawn by the human-computer conversation of other users cannot be traced back.
D. Only the pending faults can be traced back.
If multiple results (failures) are pushed out of a man-machine session, all the results need to be traced back if the results are to be traced back and answered again.
It should be noted that the system provides a backtracking function to make the user use the system more conveniently, which is a remedy for some misoperation of the user, but the user should take action as cautiously as possible in the human-computer conversation process to avoid repeated backtracking at will.
After the current fault is processed, the current fault information can be processed by clicking an end button, and the system obtains an exact diagnosis result at the moment. (this button is not available when the fault is not completed.) when the fault is completed, request must be selected, otherwise no statistics can be made for the fault.
When the fault is ended, the system provides a note book, and some events in the fault diagnosis and treatment process can be recorded for future reference.
Alternatively, if the user does not have the right to process the fault under the current working condition, the user needs to transfer the fault to the user with the right to process the fault by clicking the transfer button (for example, when the operator cannot process the fault, the operator needs to transfer the fault to the maintainer through the transfer function). The system also has an automatic transfer function, and even if the fault needing transfer is not manually transferred, the fault can be automatically transferred when the system state is switched.
In the embodiment of the invention, all the faults of the generator are found through the man-machine conversation, the diagnosis result is comprehensive, and the operability is strong.
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 invention.
