Technical Field

[0001] The present invention relates to the technical field of relay protection training, and more specifically, to a relay protection mirror simulation training system. Background Art

[0002] Relay protection can ensure the safety and normal operation of the power system, and is one of the most practical and effective technical means for the maintenance and protection of the power system. The smooth implementation of relay protection operations, while eliminating power failures, not only ensures the normal operation of social life and economy, but also guarantees social stability and the safety of people's lives and property to a certain extent.

[0003] At present, a new power system with new energy as the main body is gradually taking shape, and the power system regulation and fault mechanism will become more complex. Therefore, the new power system has put forward higher requirements for the secondary professional operation and maintenance management level of the power grid. At the same time, the increasingly complex environment has put forward higher standards for the emergency response and fault abnormality handling capabilities of the operation and maintenance personnel, requiring the operation and maintenance personnel to be on duty on a regular basis and be familiar with the relevant skills required for duty, including the steps, process methods of business operations such as access substation debugging, remote control, and daily operation and maintenance, as well as emergency handling skills in the event of power grid failure, protection alarm, system operation abnormality, network abnormality, etc.

[0004] In order to improve the operation and maintenance level of operation and maintenance personnel, it is necessary to train them. At present, the training of relay protection at the dispatching end mainly adopts the method of learning the prescribed materials in the regulations and is carried out in an offline form. This method is difficult to systematically reflect the problems and phenomena in the process of power system failure and abnormality. Trainees lack practical operation and disposal, and it is difficult to improve their experience and skills. Summary of the invention

[0064] The simulation operation application unit is used to simulate relay protection simulation training services and provide relay protection simulation training service operation applications;

[0065] The alarm monitoring unit is used to monitor the abnormalities and errors that occur during the training operation of the operation and maintenance trainees, and issue alarms;

[0070] The lesson plan management unit is used for teachers to prepare training plans, set up training plans and manage historical lesson plans.

[0071] The relay protection mirror simulation training system proposed in this embodiment supports the open setting of simulation application functions and the editing of simulation processes of various functions, and supports teachers to browse and compile detailed operation processes of designated simulation applications. The teaching plan management unit also includes teacher preparation and sending of teaching plans and historical teaching plan management.

[0072] like Figure 3 The lesson plan preparation process shown is carried out by the following steps:

[0073] (1) The instructor creates relay protection simulation training scenarios for operation and maintenance trainees based on the production plant simulation basic model, determines the number of plants and stations included in each simulation scenario, and forms a simulation basic model;

[0074] (2) Back up the model section data of the plant;

[0075] (3) The teacher frames the relevant plants based on the simulation basic model, forms a new simulation scenario, or calls the historical simulation scenario in the historical teaching plan for modification. When the teacher chooses to modify the historical teaching plan, the system compares the plant model in the historical teaching plan with the real-time plant model. If there is a difference, a prompt is given, and the teacher can choose whether to replace the new plant model;

[0076] (4) The instructor selects the simulation application supported by the system, compiles the training content, and sets the training standards, including normal, error, and corresponding correct operation standards; the events of the simulation application can be set to occur regularly or at a specified time;

[0077] (5) Edit the existing fault reports in the database module to form typical fault handling training cases and system operation typical abnormal handling training cases. The cases support the setting of abnormal scenarios such as incomplete report information, missing / wrong action events, missing / wrong recordings, and incorrect analysis results;

[0078] (6) The instructor sets simulation-related parameters, including plant-station communication parameters, line parameters, device maintenance signboard, and device setting sheet;

[0079] (7) Set the training start time, duration, and lesson plan name;

[0080] (8) After the lesson plan is completed, the lesson plan name, creation time, training content, trainees, scores, and plant model sections backed up during this training will be saved in the database module.

[0081] The instructor frames the production plant based on the production plant simulation basic model, forms a new relay protection simulation training scenario, or calls the historical relay protection simulation scenario in the historical training lesson plan for modification. When modifying the historical training lesson plan, the production plant simulation basic model in the historical training lesson plan is compared with the real-time production plant simulation basic model. When there is a difference between the production plant simulation basic model and the real-time production plant simulation basic model, the lesson plan management unit gives a prompt, and the instructor chooses whether to replace the production plant simulation basic model;

[0082] Receive and edit existing fault reports in the operation information in the database module to form typical fault handling training cases for the device and typical abnormal handling training cases for system operation; the instructor sets the simulation parameters, sets the training start time, duration, and lesson plan name, and after the training plan is compiled, save it to the database module.

[0083] The training management unit is used to manage training matters, including starting training, pausing training, resuming training, replaying training and inserting temporary training events; starting training: after the instructor confirms the lesson plan, he / she presses the start button, the training starts and the timing starts, and the timing of related scheduled services set in the lesson plan also starts at the same time; pausing training: during the training process, it supports pausing the specified training service, the timing stops, and the timing of related scheduled services set in the lesson plan is also paused at the same time; resuming training: after the training is paused, it supports resuming the specified training service, the training can continue, and the timing of related scheduled services set in the lesson plan resumes; replaying training: after the training is completed, it supports replaying the training process records; inserting training events: during the training process, the instructor can temporarily insert events and send them immediately to relevant operation and maintenance trainees.

[0084] The preset plan management unit is used to preset training plans; it supports instructors to preset training plans and send them to operation and maintenance trainees at regular intervals, or allows operation and maintenance trainees to call them during personal simulation exercises.

[0085] The trainee monitoring management unit is used to monitor the abnormalities that occur during the training process of the operation and maintenance trainees, the results of fault handling, the notification information during the interactive training with the instructor, the notification of the completion of the training, and the notification of personal simulation training;

[0086] The evaluation management unit includes an objective evaluation subunit and a subjective evaluation subunit. The objective evaluation subunit is used to provide quantitative evaluation results of operation and maintenance trainees, and the subjective evaluation subunit is used to provide subjective non-quantitative evaluation results of operation and maintenance trainees. The evaluation management unit outputs a comprehensive evaluation result based on the quantitative evaluation result and the subjective non-quantitative evaluation result.

[0087] Specifically, the objective evaluation subunit provides the quantitative evaluation results of the operation and maintenance trainees in the following steps:

[0088] (1) The instructor browses and edits the process steps of typical simulation application business;

[0089] (2) The instructor first sets the total score for the simulation application, and then sets a quantitative score for each step based on the importance of each operation step;

[0090] (3) During the student's operation, the system records the correct and incorrect results of each step;

[0091] (4) After the student completes the operation, the system automatically calculates the total score based on the scoring criteria set by the instructor and the student's operation results.

[0092] The steps for the subjective evaluation subunit to provide the subjective non-quantitative evaluation results of the operation and maintenance trainees are as follows:

[0093] (1) The instructor records the overall evaluation and guidance suggestions of the trainee's operation;

[0094] (2) Record the trainee’s satisfaction with the operation, including excellent, good, average, and poor.

[0095] (3) Support teachers to set standard scores for excellent, good, fair, and poor;

[0096] The evaluation management unit outputs the comprehensive evaluation results according to the quantitative evaluation results and the subjective non-quantitative evaluation results as follows:

[0097] (1) Support teachers to set the proportion of objective and subjective evaluation in the final score;

[0098] (2) Automatically calculate the comprehensive score based on the set proportion. Comprehensive score = objective score × proportion + subjective score × proportion;

[0099] (3) Keep records of the details of each training session, including: name of the trainee, operation time, name of the lesson plan, overall score, objective score and scores of each step, subjective score and instructor's suggestions, etc.;

[0100] (4) Supports statistical analysis of students' historical training scores in the form of line charts, bar charts, etc., visually displaying the students' growth trajectory.

[0101] (5) Support ranking of trainees’ training results by training content.

[0102] In this embodiment, in the simulation scenario management unit, the relay protection simulation training scenario loaded by the operation and maintenance trainee includes a real-time teaching plan scenario and a historical teaching plan scenario. The real-time teaching plan scenario is a relay protection simulation training scenario in the training plan issued by the instructor, which is created based on the production plant simulation basic model. After the operation and maintenance trainee logs in to the login registration center module, he completes the simulation training according to the relay protection simulation training scenario model corresponding to the real-time teaching plan scenario;

[0103] The historical teaching scenario is used for daily skill training of operation and maintenance trainees. The simulation scenario management unit detects whether the historical teaching scenario is compatible with the production plant simulation basic model, and gives a prompt when it is not compatible. The operation and maintenance trainee decides whether to continue. When the operation and maintenance trainee chooses to continue, the simulation scenario management unit sends a simulation exercise notification to the instructor, and then starts the training;

[0104] After the operation and maintenance trainees finish the training operation, they save the relay protection simulation training scenario model data as a section information file and store it in the database module.

[0105] After the operation and maintenance trainees load the relay protection simulation training scenario, they enter the training state. In the training state, the production plant and equipment names simulated by each operation and maintenance trainee are consistent with the real-time state, but the equipment ID is different. They are numbered according to "original production plant / equipment ID_user ID_production plant state" to form a unique identification.

[0106] For the teaching simulation scenario of the same section, the self-recovery technology of differential instantiation is used to create the same simulation scenario for each operation and maintenance trainee, which effectively solves the scene model conflict problem when multiple operation and maintenance trainees simulate the same production plant, and ensures that the device names displayed on the simulation interface of each operation and maintenance trainee are consistent.

[0107] Example 3

[0108] This embodiment illustrates the relay protection simulation training service. In this embodiment, the relay protection simulation training service includes an operation and maintenance simulation training service, a power grid fault handling simulation training service, and a remote control operation simulation training service.

[0109] During specific simulation training, a wizard-style method is used to guide operation and maintenance trainees to complete simulation operations. Operation and maintenance trainees are supported to complete operation result confirmation in different ways such as single selection, multiple selection, and text input, and record and save them. The system promptly gives prompts on whether the operation results are correct or not according to the standards preset by the instructor. Operation and maintenance trainees conduct simulation training according to the prompts, and can repeatedly practice the current step content and proceed to the next step after becoming proficient in it. The system interface proposed in this embodiment supports visual display of each operation step in the form of a flowchart, and presents the operation results of each step in different colors (green: correct, red: wrong, blue: not performed). When an abnormality or error occurs during the trainee's operation, it supports prompting in the form of an alarm window.

[0110] The operation and maintenance simulation training business includes: data blocking treatment simulation training, IP blocking treatment simulation training, device operation abnormality treatment simulation training, power system operation abnormality treatment simulation training, device maintenance hanging treatment simulation training, production plant substation access simulation training;

[0111] Among them, data blocking handling simulation training is used to simulate the high-frequency alarm transmission of a small number of non-important signals in actual production plants and stations, and train operation and maintenance trainees to handle the abnormal high-frequency alarm transmission of a small number of non-important signals;

[0112] The specific steps are:

[0113] (1) When an abnormality is found, the training lesson plan presets the normal transmission signal and includes several high-frequency transmission signal points. By publishing the lesson plan, the corresponding students are selected and the simulation substation is notified to send the signal content preset in the lesson plan. The corresponding data model is generated according to different students. Students need to find the frequent data signal in the simulation operation and enter the plant name, equipment name, signal point name and judgment conclusion of the frequent signal in the operation conclusion through options and subjective conclusion filling;

[0114] (2) Data suppression: After the trainee completes the suppression operation of the corresponding signal point through the interface, he / she can input the operation conclusion through the options in the operation conclusion;

[0115] (3) Check the results. After checking whether there are still a large number of frequent data, the students can enter the check conclusions through the options in the operation conclusion;

[0116] (4) Release the suppression. After receiving the abnormal signal sending completion notification preset in the teaching plan and sending it to the simulation substation, the students complete the release of the suppression of the corresponding signal point through the interface, and enter the operation conclusion through the option method in the operation conclusion. The system prompts whether the release is successful.

[0117] (5) Report results: Students input reasons and treatment results through the interface and send a notification to the instructor.

[0118] IP blocking handling simulation training is used to simulate the traffic storm caused by network anomalies in production plants and train operation and maintenance trainees to handle such anomalies. The specific steps are as follows:

[0119] (1) When an abnormality is found, the training lesson plan presets a normal signal transmission and includes a large number of high-frequency transmission signals. The simulation substation is notified to send the signal content preset in the lesson plan to simulate a network storm. The trainees need to find the relevant substations that frequently send data signals and enter the plant station name and IP address of the frequent signal through options in the operation conclusion;

[0120] (2) Block the IP. The trainee disconnects from the substation through the interface and modifies the firewall configuration to prohibit the corresponding plant station IP address from communicating with the main station. Then, the trainee enters the operation conclusion through the option mode in the operation conclusion.

[0121] (3) Check results: After checking that the network storm has been eliminated, the trainee can enter the check results through the options in the operation conclusion;

[0122] (4) Unblocking. After receiving the abnormal end notification preset in the teaching plan and sending it to the simulation substation, the student modifies the firewall configuration through the interface, removes the restrictions on the corresponding IP, reconnects to the substation, and enters the operation conclusion through the options in the operation conclusion. The system prompts whether the unblocking is successful.

[0123] (5) Report results: Students input reasons and treatment results through the interface and send a notification to the instructor.

[0124] The simulation training for handling abnormal operation of the device is used to load the typical fault handling training case scenarios pre-set by the instructor, and simulate the occurrence of important alarms in the device to train the operation and maintenance trainees to detect and handle alarms; the specific steps are:

[0125] (1) When an abnormality is found, the training lesson plan presets the sending of device alarm signals, such as PT disconnection, channel interruption, etc. Trainees need to find the device alarm and enter the plant station name, equipment name, and signal point name of the alarm device through options in the operation conclusion;

[0126] (2) Alarm handling: students send alarms to the instructor through the interface, and notify on-site personnel to eliminate the faults after simulating abnormalities;

[0127] (3) Confirmation of treatment: After receiving the alarm recovery notification preset in the teaching plan, the trainees check whether the device alarm has been eliminated and enter the treatment completion through the option method in the operation conclusion.

[0128] (4) Report the results. Students enter the cause and the result through the interface and send a notification to the instructor.
