Description

Virtual fault simulation system of electric power system using GUI and Data Base and method for employing as the same}

The present invention relates to a power system simulation failure system and its operation method, in particular, power system simulation using a GUI and database to meet the needs of the operator support system for rapid and reliable recovery, or failure and recovery simulator. It relates to a failure generating system and its operation method.

Over the past few decades, power systems have become increasingly complex and enormous, making it difficult to operate them reliably. In addition, although SCADA (Supervisory Control And Data Acquisition) or EMS (Energy Management System) is installed in the power system to assist the operator, the task of the operator is still complicated, and the need for the ability to safely drive the power system continues to increase. have. Among these realities, the advancement and the digitization of driving facilities are increasing this tendency. Accordingly, there is a need for an experienced driving technique for the power system, and a need for acquiring an unexperienced fault handling technique through actual power system simulation. The completed 765 [kV] power system is much more complex than the previous 154 [kV] and 345 [kV] systems and has a greater impact on the entire system in the event of a fault or misoperation. It is becoming.

In addition, since the system operation system is mainly composed of remote monitoring and remote control functions in a normal state, recovery operation in the event of an accident has been largely dependent on the expert's expert knowledge or empirical judgment. Therefore, if the operator misjudges the accident situation or performs wrong operation in the recovery operation stage, it may not only cause a great disruption to the power supply but also damage the equipment. Therefore, prompt judgment of the accident situation and reliable prompt recovery of the blackout area are very important issues. However, in recent years, as various facilities of the power system are complicated, the occurrence of accidents is gradually reduced due to the improvement of the reliability and the function of the power facilities, even though more related knowledge or experience is required from the operator when an accident occurs. As a result, the opportunities for experiencing system operators' failures are also decreasing. Therefore, there is a growing demand for operator support systems or failure and recovery simulators for rapid and reliable recovery.

In this way, since the occurrence of accidents is gradually reduced due to the improvement of reliability and function of electric power facilities in recent years, the chance of experiencing the failure of the system operator is also reduced, so that the operator support system or failure occurrence and There is a growing demand for recovery simulators. These simulators have been studied in many parts for a long time and are still being studied. However, at present, the simulator is complicated to use, and the recovery operation after the failure remains at the level of simply acquiring the recovery procedure as text. .

Accordingly, an object of the present invention is to adopt a method of storing and inquiring a simulated failure scenario using a database while the user easily generates a failure in the power system using a GUI, and semi-permanently stores the failure type using a database. In addition, the present invention provides a power system simulation failure occurrence system using a GUI and a database that can be easily added and deleted using a GUI, and an operation method thereof.

In particular, the simulation system of power system using GUI and database and its operation method is to implement the simulator to learn the 765 [kV] power system system, generate the fault according to the simulation failure scenario, and recover the fault. The purpose.

The simulator to be implemented in the present invention is provided on three PCs to provide a power system simulation failure generation system using the GUI and the database and its operation method to achieve the following purposes in a GUI (Graphic User Interface) environment.

In order to assign various training and training situations to the training center and to handle the control of the training center, SimWS is prepared by connecting the MPU to the network to acquire necessary data, storing the received data in a local database, and providing system data. It is equipped with an algae calculation program that reads and calculates the algae of the entire substation, and sends event messages to clientLink, which updates the shared memory so that the system can experience the same changes as the substation site, and the clientLink uses the received data. Instructor control panel to create a shared memory by; The simulated failure scenario selected by the instructor consists of serverLink that receives the clientLink, OPC, a process that monitors and controls the system, and GUIDE, which performs any tasks required for education and training. A simulation control panel which is implemented in the same manner as the supervisory control panel to be used, which generates simulation simulations in software and stores data downloaded from the MPU in a simulation database; And stores data related to monitoring, control and measurement, simulated database built with ind_point, ana_point, cal_point and rtu_point tables, and information related to training, scenario, resto_p, ann_p, fault_p, analog_p and relay_p tables. And a database including a training database constructed with a training database storing training results and a training result database constructed with a trainee, train_result, and subicon_result tables.

At this time, the training database is configured to separate each database having the resto_p, ann_p, fault_p, analog_p, relay_p table from the scenario database, and this database has a resto_p, ann_p, fault_p, analog_p, relay_p table It is preferable that are respectively connected.

In addition, the database includes a database related to algae calculation including a bus table, a track table, a transformer table, a Sh.R table, a breaker table, a disconnector table, a breaker group table, a bus-tie CB table, and a tap ratio table. It is more preferable that it is further included.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a view showing the position of the simulation by the classification of the system analysis method. As shown in FIG. 1, an analysis of a system existing in the real world may be classified into an analysis through an experiment on an actual system and an analysis through an experiment on a model of the system. Experiments on real systems are costly and do not apply well to real inventions because they can destroy systems. The latter system model can be further classified into physical and mathematical models. The physical model is to reconstruct the model by miniaturizing a physical system such as miniature, but most of the systems in the real world are often unable to reconstruct the physical model. Analysis of mathematical models can be divided into analytical methods and simulation methods. If the model components of a particular system have simple relationships, mathematical methods such as algebra, calculus, and probability theory can be used to obtain accurate information. However, systems that exist in most real worlds are too complex to construct a real model for analytical evaluation. Therefore, most system analysis is done by simulation. In this way, the simulator can be defined as a simulation software that connects a part or the entire target system and human interaction with a computer through an input / output interface, and a user with no programming knowledge or a little programming knowledge can use a GUI. It allows you to simulate systems of a particular class. The advantages of these simulators are their ease of use through the GUI and shorter development time than developing simulation languages. The configuration of the simulator for performing such a simulation is configured as shown in FIG.

2 is a diagram showing the configuration of a software-based 765 [kV] training simulator for modeling a substation and a supervisory control panel. As shown in FIG. 2, the educational simulator is composed of an instructor operation panel 100 having a simulation computer and a simulation control panel 200 having a training computer. As such, the 765 [kV] educational simulator comprises a simulation control panel 200 implemented in the same manner as the actual monitoring control panel 300 and an instructor operation panel 100 which gives various training and training conditions to the training staff and handles the control of the training staff. do. In other words, the simulation computer performs a scenario providing function that is manipulated by an instructor, and the training computer performs a function of causing the trainer to respond to the virtual scenario. A plurality of training computers are provided so as to be connected to the simulation computer by a network. Such modeling is made by connecting the simulation control panel 200 and the instructor operation panel 100 to each other by applying that the substation 400 is connected to the monitoring control panel 300 in the actual system.

On the other hand, the educational simulator should be able to mock education and training with the same standard and screen configuration as the system that is actually operating while transmitting and receiving data in real time, and the data to be transmitted and received is considered in various situations that may occur in the field. Therefore, the field operation environment should be able to be implemented as it is. This is to eliminate any system misoperation or gap that may come from the difference between the training system and the actual driving system. Therefore, the simulator must satisfy the following requirements.

All monitoring and control functions of the monitoring control panel 300 should be implemented in the simulator.

The simulator should be implemented with the same MMI (Man Machine Interface) as the monitoring control panel 300 of the substation 400 actually operated.

ㆍ The method of inputting the setting value necessary for the screen composition and the device operation should be the same.

As described above, the simulator of the present invention implements the education and training function, and if any scenario is selected in the instructor operation panel 100, the corresponding scenario is generated in the simulation control panel 200, and the education and training proceeds. At this time, the selected scenario should be produced in a situation that can occur in the substation 400, the monitoring control panel 300, so that a series of operation actions performed in the field is displayed on the simulation control panel 200 as it is. In particular, the value of the algae that is changed in real time in the system is calculated through the algal calculation program of the instructor operation panel 100, and must be produced in the simulation control panel 200. In addition, after education and training are completed, interactive programs should be developed to provide explanations for automatic assessments and incorrect answers.

3 is a flowchart illustrating a design process of a database. In the simulator shown in FIG. 2, a database is required to implement various types of failures of the power system in a scenario form. This database is a data storage and data storage system that can efficiently improve the existing information storage method and manage it in an integrated manner. It is designed through the following process.

First, the requirements gathering and analysis process is the process of deriving the structure of the database from the user's needs. It is the view of data driven, processing driven, work or process and the flow of information between them. This is a design phase in which the data used in the application is identified and determined in what form.

Second, the conceptual database design step uses a conceptual schema as a step in designing a conceptual database from the specified requirements to the entity-relational model to be used in the present invention. Conceptual schema is a high-level description of the database structure, independent of the specific Database Management System (DBMS) software used to build the database. Conceptual schema modeling uses object-relational diagrams. Herein, an entity means a basic object that exists independently, and an attribute means its own characteristic of an entity. The selection of individuals should be based on ① being of constant interest, ② having unique characteristics that can be distinguished from other entities, ③ excluding redundancy, and ④ storing data. As shown in Figs. 4 to 7, the diagram according to the objects, attributes, relationships is shown according to the present invention.

Third, the logical database design phase is to design a logical schema. A logical schema describes a database structure that can be processed by the DBMS software. In other words, the database objects are represented as tables according to the object-relationship diagram defined in the conceptual database design phase of the second stage. Tables 1 and 2 below are part of the actual designed database. Table 1 is a scenario table and Table 2 is a recovery procedure table.

Table 1

Fourth, the physical database design step designs the physical database as a relational database to be used in the present invention. This is the process of connecting the database using the object-relationship diagram defined in the conceptual database design in the second stage and the table defined in the logical database design in the third stage, and implementing the database in auxiliary storage.

On the other hand, in order to build such a database is connected to the monitoring control panel of the actual substation to receive and store the failure situation occurring in the actual power system, the overall system configuration is made as shown in FIG.

Referring to FIG. 8, reference numeral 310 denotes a main processing unit (MPU) 310, 320 denotes an operator console (320), 330 denotes a communication control unit (CCU) 330, and 340 denotes a database input unit (340). , Instructor operation panel 100, simulation control panel 200, recording devices 250, 350, LAN 500, and the like. The MPU 310 transmits the state of the field device from the CCU 330 to the OPC 320, and delivers the operator's instructions to the CCU (330). The OPC 320 monitors the state of the system and the field equipment through various operation screen manipulations, and receives the operator's instructions and transmits them to the MPU 310. The DIU 340 is a device for editing and inputting various data required by the MPU 310, the OPC 320, the CCU 330, and the like. The instructor operation panel 100 may be connected to a network with the MPU 310 to acquire various necessary data.

The development environment of the simulator to be implemented in the present invention was implemented using Visual C ++ in MS-Windows 2000 Server and Professional as shown in Table 3 below, and the DBMS used Oracle 8i.

Looking at the hardware configuration, database configuration of the instructor operation panel and the simulation control panel connected to the monitoring control panel as a network.

First of all, as a computer to be used as an instructor operation panel, a workstation with excellent computing power and graphic processing function is used, and it has an international standard OS suitable for real time and simultaneous work processing. The Instructor Control Panel performs smoothly in terms of memory capacity and speed to acquire real-time data from the MPU, and has a scalable and flexible system such as an open architecture system specification so that it can be easily replaced with a new model when the model is discontinued in the future. Consists of Table 4 shows the hardware specifications of the instructor operation panel to be used in the present invention.

Table 4

On the other hand, the computer to be used as the simulation control panel is the latest high-performance PC, Pentium IV class, equipped with the international standard OS to perform OPC function, and to perform education and training, it shows smooth performance in memory capacity and speed. The overall system specifications are mostly the same as the Instructor Control Panel (HP X2000, 21 "Color Monitor 1 Set).

On the other hand, the software used in the instructor operation panel and the simulation control panel is as follows.

The Instructor Control Panel uses SimWS.EXE and clientLink.EXE. First, SimWS.EXE is responsible for the MMI for the instructor, and is equipped with the functions of performing MPU roles, generating education and training messages, adding and editing databases, and performing OJT. . In addition, it saves and retrieves training data, saves and initializes the system status as a file, and downloads data from the MPU. The following is the main operation mode of SimWS.EXE and a description of each mode.

① Operation Mode-A mode that acts as an MPU to handle the control of the training center in the simulation control panel.

② Education / Training Mode-Mode for generating education and training messages

③ Simulation control panel DB editing mode-Editing database such as simulation failure scenario and recovery procedure

④ OJT Mode-Mode to perform OJT

⑤ Training data-Function to save and search training data

⑥ Data Acquisition Mode-Function to download data from MPU

⑦ Save system status file-Function to save current system status as file

⑧ Initialization-Function to initialize system status by downloading or saving files from MPU

The clientLink.EXE is responsible for the communication between the instructor operation panel and the simulation control panel, manages the shared memory, and loads the algal calculation program to calculate the algae according to the system change in real time so that the simulation control panel appears.

Next, the simulation control panel uses OPC.EXE, serverLink.EXE, and GUIDE.EXE. OPC.EXE uses the monitoring control panel to eliminate any system misoperation or discomfort that may come from the difference between the actual operating system and the training system. Implemented in the same way as OPC, serverLink.EXE is in charge of communication between the instructor operation panel and the simulation control panel, and delivers the education and training messages from the instructor operation panel to OPC.EXE so that the education and training situation occurs in the system. GUIDE.EXE is in charge of MMI between the simulation control panel and the training center for training and training, and proceeds with the training and training messages received from the instructor operation panel.

9 is a diagram showing the relationship between the databases actually constructed in the present invention. Referring to FIG. 9, a monitoring panel database is constructed in the monitoring control panel, and SimWS.EXE stores data downloaded from the MPU in the simulation panel database. The simulation database is a database that stores data related to monitoring, control, and measurement. It is composed of ind_point, ana_point, cal_point, and rtu_point tables. In addition, a training database that stores information related to training is constructed of scenario, resto_p, ann_p, fault_p, analog_p, and relay_p tables, and the training result database that stores training results is constructed of trainee, train_result, and subicon_result tables.

In the present invention, a database is designed in consideration of a case where data stored in a database is variably increased or decreased. For example, in the training database, the data of the failure point, the motion indicator point, the analog point, the relay point, and the recovery procedure vary depending on the scenario. Therefore, the training database is configured separately from the scenario database, and each database is connected with the scenario number. . Therefore, the data that can be stored in the database can be stored indefinitely as the capacity of the database allows, one feature is to design a more flexible database.

Here, let's take a closer look at the tables in the training database.

First, a scenario table is a table in which list information of a scenario used for education / training is input, and contents as shown in the following table are stored. At this time, the recovery procedure icon represents each step of the standard procedure using the letters A to L.

11 is a diagram showing the process of the overall system including the monitoring control panel and the simulator. First, reference numerals used in the process processing will be described.

C: network communication

E: event message

U: shared memory update

A: database access

SHM: shared memory

Referring to FIG. 11, the CCU uses a MNP side and a DNP protocol as a process for receiving field data or delivering data to the field. simServer is a process of transferring the shared memory on the MPU side to the simulator. When simWS requests, simServer transfers the shared memory through network communication. SimWS stores the received data in a local database, sends event messages to clientLink, and clientLink uses the received data to create shared memory.

When accessing a local database, SQL * Net is used to directly access an Oracle DBMS. Programmatically, it is coded as an ADO (ActiveX Data Objects) interface. Internal processes send and receive event messages through IPC (InterProcess Communication), and external processes send and receive information via socket communication. The algae calculation program installed in clientLink calculates algae of the entire substation by reading the data of the system and updates the shared memory so that changes in the system can be experienced in the same way as the substation site. This is the process necessary to carry out the functions of monitoring and control of the system. GUIDE performs all the tasks necessary for education and training. The external processes of FIG. 11 exchange information through UDP communication, and the internal processes exchange event messages through IPC. In other words, clientLink and serverLink processes and simServer and SimWS processes exchange information using UDP communication. SimWS and clientLink processes communicate, serverLink and OPC processes, and serverLink and GUIDE processes communicate via IPC. Send and receive events. Tables 5 and 6 below summarize the protocols defined for UDP and message communication via IPC.

12 is a flowchart schematically illustrating the education and training procedure of the simulator.

Here, the simulator basically operates in an operation mode to perform an MPU role (S10). As shown in FIG. 12, in order to start training and training, the instructor switches to the training / training mode through MMI (S12), selects a scenario (S14), and checks whether the trainee is logged in (S16). This login starts education and training (S18). According to the scenario selected by the instructor, the training center proceeds to education and training (S20), and the simulator monitors the training center operation and system control in real time and displays information including the correct answer on the instructor monitoring screen (S22). At this time, the instructor operation panel primarily determines whether or not the restoration is completed (S24), and when the restoration is not completed, it is secondarily determined whether the training center ends the education and training (S26). On the other hand, when the recovery and training is terminated in steps S24 and S26, the operation history evaluation screen is automatically generated for the recovery history manipulated by the trainer through the MMI to calculate the operation score, and the information is stored in the database. do. The calculation of the operation score is calculated by the ratio of the accuracy of the operation history (70%), the time required for the operation (20%), and the instructor evaluation (10%), and the ratio can be changed variably through the configuration (S28). ). When the education and training is finished, the instructor operation panel is switched to the operation mode to perform the MPU role (S30).

As shown in FIG. 12, when education and training is started, the training center performs the recovery operation in the order of the scenarios set in the simulation control panel. Table 7 below describes the sequence and meaning of these recovery operations.

Table 8

Computer type Program name Remarks / Sim / WS ① ClientLink Communication program ② SimWS Instructor Program for Education / Training ⑵ Sim / PC ① ServerLink Communication program ② GUIDE Training program for education / training ③ OPC Operator Console Program

In order to start the simulator, the above programs must be executed. Each program can be executed in the same manner as the environment setting program on each computer. If necessary, the shortcut icon of each program can be copied to the desktop.

First, Sim / WS executes the program in the following order.

① Run the ClientLink program.

② Run the SimWS program.

In Sim / WS, the above two programs should be executed in order. Next, Sim / PC program will be executed. GUIDE program among Sim / PC's program is executed automatically when the training / training starts. Therefore, it is not executed to start the simulator. In Sim / PC, execute the program in the following order.

① Run the ServerLink program.

② Run OPC program.

By running all four programs through the above procedure, the simulator is started.

When the simulator is driven like this, education / training starts.

The instructor can execute by selecting [Training / Training Mode], which is a submenu in the [Mode] menu, in the menu of the SimWS program, and the screen shown when the teaching / training mode is executed is shown in FIG. 55. The instructor selects the type and type of scenario and then selects the scenario to be trained / trained. When the instructor selects a scenario to be performed in the above screen and drags it, the corresponding scenario appears on the screen as shown in FIG. At this time, select the training mode, the individual training scenario of the advanced difficulty among the entire scenarios, select the scenario to be trained / trained, and also select the team training in the training type selection in order to train the team. The selection of the training / training scenario is made by dragging and dropping the scenario to be executed and dropping it under the [Execute] button.

After that, when the instructor clicks the [Run] button, the instructor can start training / training. It should be noted, however, that you can run it correctly only by clicking on the [Run] button while clicking on the selected scenario. In addition, before clicking the [Run] button, the instructor should check whether the trainees have logged in through the GUIDE program that is automatically executed in Sim / PC. If the click the [Run] button before logging in, the warning message is displayed. do.

In any case, if the scenario is executed correctly, a confirmation window is displayed to start the education / training, and the education and training starts in earnest. When training / training starts, the screen shown in FIG. 56 is displayed in Sim / WS to confirm the training / training procedure performed by the training center. For individual training, select the scenario shown in another List (Scenario for Sim / PC # 2) located at the bottom of the screen in FIG. 56 and click the [Run] button directly above the list to start training in Sim / PC # 2. Can be.

On the other hand, when the training / training mode is executed, the GUIDE program is automatically executed in Sim / PC. As such, when the GUIDE program is executed, the instructor must log in before the instructor begins training / training. As shown in FIG. 34 to FIG. 36, when the login window appears, the training institute is performed by clicking the [Log In] button. At this time, if the training center does not log in, education / training is not performed. If you click the [Log In] button, the instructor enters the name, number and business name respectively. If the login is successful, the GUIDE program will confirm that the training information has been entered into the GUIDE program. At the same time, the GUIDE program stores the training name, employee number, login time, and business name in the database and waits for training / training to begin.

When training / training starts from the instructor, the GUIDE program is run automatically, showing the trainers the screens required for each stage of the training / training. After that, as the first step of education / training, the instructor recognizes the failure by clicking [Alarm event (cognition)] in the OPC program, and then selects the [OK] button. Education / training is conducted to check the situation. At this time, each time the instructor performs each step, the SimWS program outputs the instructor to check the training and operation of the instructor through the window of FIG. 56.

After the trainee has identified the failure, the trainee will continue with the next step, the first occurrence status check. After checking the breakers or relays operated on the screen output as shown in FIG. 37, the trainer selects by clicking the check box next to it. Also check the changes in tidal current values displayed on the OPC and select the corresponding check box as well. If there is anything else to enter, enter it in the Other field. After that, when the trainer selects the [OK] button at the bottom, the GUIDE program shows the CCTV screen of the site. The trainer checks the CCTV screen and then clicks the OK button to proceed to the next step.

Next, as shown in FIG. 39, only the LED status of the currently operated relay is checked through the protection panel monitoring screen, and as shown in FIG. 41 to FIG. In this case, when the point information to be operated appears in the relevant column, the training center controls each point indicated in the list on the OPC, if there are internal power supply points, and then clicks the [OPC Operation Confirmation] button on the screen, and then [OK]. Click the button. In the next process, the first report is made, and the preliminary information shows what the trainer confirmed, manipulated, and other inputs, and the times for each. The training center checks each item on the screen, and if there is anything else to input, it enters in the other input column. When all the contents of the report have been confirmed, the training staff clicks the [OK] button at the bottom to proceed to the next step.

 The next step is the field check and reset step, and the trainee instantaneously checks the actual substation in the screen as shown in FIG. 44. The GUIDE program provides a screen as shown in FIG. 44, and the training center checks each region by clicking an icon corresponding to the region to be patrolled. The GUIDE program provides an actual picture of each area, which appears when you click on each area. It is configured in the same way as the actual substation layout, and it can be identified by dividing it into BAY, on-site control building, and M.TR. The training center should check the area that needs to be checked by clicking a button on the screen of FIG. 44, and when each button is clicked, a picture and a video as shown in FIG. 45 can be checked. In the case of devices such as M.TR, Sh.R and BAY of each site, only the corresponding pictures as shown in FIG. 45 are confirmed, and the screen returns to the site area screen after confirmation. In the case of the site control building, the device arrangement diagram as shown in FIG. 46 is shown. As shown in the screen of FIG. 46, an icon called [need to confirm] exists in the case of the relay PANEL which requires confirmation, and an icon called [not required to confirm] exists in the case of the PANEL not operating. If you click the [Not required] icon, a warning message appears. When the [Confirm Needed] icon that requires confirmation is clicked, the screen of the corresponding PANEL as shown in FIG. 47 appears. When the training center displays a screen as shown in FIG. 47, checks each point displayed on the LCD screen, and then checks a check box on the left side. In case relay PANEL appears, check each and finally click [OK] button. At this time, the corresponding PANEL screen is closed, and the device arrangement diagram screen of FIG. 46 is displayed again. After completing the confirmation of all the devices that need confirmation on the device arrangement diagram screen, click the [OK] button at the bottom of the screen of FIG. 46 to return to the field confirmation and RESET screen (FIG. 44). Likewise, after confirming all the sites, if the [OK] button is clicked on the screen of FIG. 44, the process proceeds to the next step of opening the pressureless device. As shown in FIG. 40, the point information to be operated appears when there is a non-pressure device to be operated. After that, the training center operates all of the no-pressure device opening points on the OPC screen, and then clicks the [OPC operation confirmation] button on the screen. When the verification step is finished, click the [OK] button to proceed to the next step.

The next step is to identify the type of failure. The training center checks the existing reports and manipulations, then identifies the type of failure and enters it into the input box. 42 or 43 is a screen for identifying a failure type step, and all items previously checked and manipulated by the training center are output in the training center operation result column, and there is a column in which the failure type can be input. Simply enter the type of failure in this field and click the [OK] button at the bottom to proceed to the next step. The next step is to receive the secondary report and recovery command, and the secondary report items are output as shown in FIG. 48. After checking the 2nd report, the training institute, if there is anything else to enter, enter it in the other field and click the OK button at the bottom. If you click the [OK] button, the trainer can perform the actual recovery operation, and the GUIDE program will inform the trainer of the point information to be manipulated. The recovery operation point is notified one by one to the trainer, and the index number of the point to be operated, the description of the point, and information on the state to be operated are displayed. After checking the above information, the instructor performs the operation on the OPC screen and clicks the [Next] button on the screen. If there are points to continue to operate, they are output sequentially, and when all the operations are completed, FIG. 49 appears next to perform a recovery operation completion report.

This screen shows the information that has been carried out so far, and there are columns for you to enter other specifics. After confirming each item and clicking the [OK] button at the bottom of FIG. 49, the GUIDE program is switched to the next step. If there are steps to repair a fault facility (e.g. breaker failure) following the repair procedure, the following confirmation window appears. Then, when all the training is finished, the end message appears and clicks the [OK] button. Then, the training is terminated and the GUIDE program returns to the initial login screen and is in a standby state.

When the trainer finishes the training in Sim / PC, the SimWS program stores the training manipulations to date in the DB, and provides a screen as shown in FIG. 19 for the instructor to make a general comment. The next screen is where the instructor enters a rating and selects an instructor score. The scores for the operation time and the number of operations are automatically calculated. On the screen of FIG. 19, the instructor records the total rating and selects the score implemented by the pull-down menu to assign the instructor score. The points thus awarded are added together and recorded in the Total Goals column. When the instructor writes down the name in the Instructor Name field and clicks the [OK] button, the training is finally terminated, and all information related to the training is stored in the DB.
