Description

  The present invention relates to a predetermined electrical accident (for example, a transmission / distribution line or a substation) in an electric power system (a system in which facilities such as transmission / distribution lines, power plants, and substations for supplying power to a power demand destination are integrated). It is used in conjunction with a simulator that simulates an electrical accident in equipment such as a power plant) and causes the operator (trainer) to perform recovery operation training in response to the electrical accident, and evaluates the recovery operation training performed by the operator. The present invention relates to a training evaluation apparatus.

  Conventionally, in training evaluation using a simulator, a trainer (instructor) directly confirms and evaluates the recovery operation and method performed by the trainer without using mechanical means. The burden and objectivity in training evaluation were particularly problematic. Therefore, so far, a driving training evaluation device (for example, Patent Document 1) that can reduce the burden on the trainer and obtain a highly reliable evaluation, and a driving training support device that further increases the objectivity of the training evaluation have been invented. (For example, Patent Document 2).

  The driving training evaluation apparatus described in Patent Literature 1 presents state recognition means for automatically recognizing the state of training from a simulator constituting the driving training environment, and evaluation items suitable for the state recognized by the state recognition means. And evaluation item presenting means. In the training evaluation, the trainer observes the trainee's state for a given evaluation item via the evaluation item presenting means, and is based on the observation result.

  In addition, the operation training evaluation apparatus described in Patent Document 2 selects the selection result of the screen (abnormal part due to accident) selection unit and operation procedure selection unit, the operation data of the plant collected by the data collection unit, and the screen to be monitored. A training evaluation unit that evaluates the training by comparing with the data is provided. The training evaluation unit calculates a goal achievement level and objectively evaluates the training. Here, the target achievement level is an evaluation of three items. The first is whether the screen is properly selected by the trainer regarding whether the screen (abnormal part due to the accident) is selected correctly. The first is to compare the operation procedure by the trainee with the procedure by the operation procedure selection unit with respect to the correctness of the operation procedure, and the evaluation is based on the number of operation errors, and the third is the screen selection and operation timing. Comparing the results of the trainee and expert, and evaluating the deviation by the deviation value.

Distributed supply. In addition, the power source B (a power plant different from the power source A) can supply 10 MW, of which 5 MW is supplied to a power demand destination (substation, house, etc.) with a load of 5 MW, and the rest 5 MW is stored as surplus power and is electrically disconnected from the power source A by the circuit breaker B1. Note that the circuit breaker B1 is normally in an open state (breaking state) and is in a closed state (energized state) in an emergency such as an electrical accident. The power source C (a power plant different from the power sources A and B) can supply 10 MW, and supplies the 6 MW to a power demand destination (substation, house, etc.) with a load of 6 MW (not shown). ), The remaining 4 MW is stored as surplus power, and is electrically disconnected from the power source A by the circuit breaker C1. The circuit breaker C1 has the same configuration as the circuit breaker B1, and is normally in an open state (breaking state), and is closed (energized state) in an emergency such as an electrical accident.

  The simulator 7 is configured to simulate a predetermined electric accident in the electric power system and cause the operator to perform a recovery operation training in response to the electric accident. In the present embodiment, as shown in FIG. The configuration itself of the control station 1, that is, the actual machine of the control station 1 can be simulated. Specifically, the simulator 7 according to the present embodiment uses the power supply range 10 by the power source A as a training target area, simulates a predetermined electrical accident in the area, and the trainer recovers from the simulated electrical accident. It is configured to build a training simulation that can be manipulated. The simulator 7 is also configured with a voice function that provides predetermined voice guidance such as cancellation of the restoration operation.

  Next, the training evaluation apparatus 2 is connected to a simulator 7 that simulates a predetermined electrical accident in the electric power system and causes an operator (trainer) to perform a recovery operation training in response to the electric accident. A training evaluation device 2 for evaluating training, a data collection unit 3 for collecting information on a recovery operation performed by an operator from a simulator, a recommended recovery operation for the predetermined electrical accident, and the predetermined electrical accident The scoring data storage unit 4 that stores the scoring data obtained by scoring the information related to the supply hindrance power caused by the time series, the information on the restoration operation of the data collection unit 3 and the scoring data storage unit 4 An evaluation unit 5 for scoring and evaluating a recovery operation training performed by an operator based on the scoring data, and a display unit 6 for displaying data are provided.

Specifically, the data collection unit 3 uses the recovery operation procedure and the elapsed time of each recovery operation (actual elapsed time of each recovery operation or within a predetermined time (for example, 5 When the simulation for training is set so that one restoration operation is performed every minute), the information regarding the supply trouble power related to each restoration operation is acquired from the simulator 7 for the predetermined time). Here, the supply hindrance power is a difference between supply power immediately before and immediately after the power supply to the power demand destination is stopped due to an electrical accident or the like.

  The scoring data storage unit 4 is configured to store scoring data that is an evaluation standard for the recovery operation performed by the trainee. Specifically, the scoring data storage unit 4 responds to information in which a recovery operation recommended for a predetermined electrical accident (recommended recovery operation) and supply disturbing power related to each recovery operation are related in time series. The scoring data with a predetermined score is stored. Here, the recommended recovery operation is, for example, a recovery operation performed by a skilled person in response to a predetermined electrical accident, and includes information related to the recovery operation procedure and the elapsed time of the recovery operation. In addition, the scoring data is created in advance for a predetermined electrical accident by giving a predetermined score to the information that relates the recommended recovery operation and the supply power that is related to the recovery operation in time series. And stored in the scoring data storage unit 4. In the present embodiment, the scoring data is a diagram in which a predetermined score is assigned to a time-series diagram that associates the recommended restoration operation and the power supply interruption associated with the operation. The given score is, for example, as shown in FIG. 4, based on supply hindrance power related to each operation of the recommended restoration operation, three areas of a high score area, a low score area, and other areas. If the trainer continues to achieve the high scoring area until the electrical accident is recovered in the recovery operation training, 100 points are set. Specifically, based on the supply hindrance power related to each operation of the recommended recovery operation, supply within a predetermined range higher than the standard by 20 points when the trainee achieves a power hindrance below the standard (high scoring area) 10 points when the trainee achieves a hindrance power (low scoring area), 0 when the trainer achieves a power hindrance (area excluding the high scoring area and the low scoring area) exceeding a predetermined range higher than the standard. Points are awarded.

  The evaluation unit 5 uses the information related to the recovery operation performed by the trainer of the data collection unit 3 and the scoring data of the scoring data storage unit 4 to score and evaluate the recovery operation training performed by the trainer. Composed. In the present embodiment, as shown in FIG. 4, the evaluation unit 5 displays the information related to the recovery operation by the trainer on the plotted scoring data, and starts from 0 based on the score given to the scoring data. Score and evaluate recovery operation training conducted by trainees within a range of 100 points. The results of the training evaluation display, for example, the elapsed time, the supply power failure (within the training target area), and the acquired points in the order of each restoration operation.

  The display unit 6 is configured to display various data. For example, in the data collection unit 3, information on the recovery operation procedure by the trainee, the elapsed time of the recovery operation, the power supply interruption related to the recovery operation, and the scoring The recommended restoration operation and scoring data in the data storage unit 4, the data in the evaluation unit 5 displayed by superimposing information on the restoration operation of the trainer on the scoring data, and the evaluation result of the restoration operation training performed by the trainer via the GUI Is displayed.

  In addition, as shown in FIG. 2, the training evaluation apparatus 2 functionally collects information related to the recovery operation by the trainee from the simulator 7 by the data collection unit 3, Using the scoring data stored in the scoring data storage unit 4, the evaluation unit 5 scores the restoration operation training performed by the trainee, and the display unit 6 displays the result of the training evaluation. Not only the result of the training evaluation but also a series of data (information related to the recovery operation, scoring data, etc.) by the training evaluation device 2 can be displayed on the display unit 6.

  Next, training evaluation using the training evaluation apparatus 2 according to the present embodiment will be described. In the present embodiment, as shown in FIG. 3, assuming an electrical accident of the power source A (power plant) in the training target area (power supply range 10 by the power source A) of FIG.

  First, the trainer uses the simulator 7 to simulate an electrical accident at the power plant (power source A) in the training target area. At this time, the circuit breaker in the vicinity of the power source A is virtually opened (shut off state), and power supply from the power source A to each power demand destination is virtually interrupted. Subsequently, in response to an electrical accident of the power source A, the trainer performs a recovery operation with the simulator 7 and information regarding the recovery operation is transmitted to the data collection unit 3 at a predetermined time interval (or immediately after each operation). Then, it is transmitted from the data collection unit 3 to the evaluation unit 5. On the other hand, the trainer, from the scoring data storage unit 4, recommends a recovery operation related to an electrical accident at the power plant (power source A) in the training area (as shown in (1) to (6) in FIGS. 1) Permanent accident occurred, (2) Circuit breaker A1 opened (break), (3) Circuit breaker B1 closed (energized), 5 MW supplied from power source B, (4) Circuit breaker A2 opened ( (Breaking), (5) closing circuit breaker C1 closing operation (energization), power supply of 4 MW from power supply C, (6) closing circuit breaker A2 closing operation (energization), and power supply of 1 MW from power supply C). When scoring data is selected or when an electrical accident in the power plant in the training area is simulated by the simulator 7, the scoring data storage unit 4 is used to perform a recommended restoration operation corresponding to the power accident in the power plant in the training target area. Scoring data is automatically selected. Then, the scoring data selected by the trainer or mechanically automatically selected is transmitted to the evaluation unit 5.

  The information regarding the restoration operation by the trainee and the scoring data transmitted to the evaluation unit 5 are displayed by the evaluation unit 5 in a superimposed manner as shown in FIG. 4 and scored based on the score attached to the scoring data. After the scoring, the training evaluation result is displayed on the display unit 6 as a table composed of elapsed time, supply trouble power, and score in the order of each recovery operation, as shown in FIGS. As shown in FIG. 5A, if the recovery operation is performed in time according to the procedure of the recommended recovery operation, an evaluation of 100 points out of 100 is obtained. Specifically, if each of the five operations (2) to (6) of the recommended restoration operation shown in FIG. 4 is performed, each of these operations corresponds to a high score area (20 points), and thus each of the five operations 20 points are added to 100 to obtain 100 points (20 points × 5). On the other hand, for example, (1) ′ to (6) ′ shown in FIG. 4 is an example of the recovery operation performed by the trainee. In this case, the trainer is (1) 'permanent accident occurrence, (2 ) 'Open circuit breaker A1 (break); (4)' Open circuit breaker A2 (break); (6) 'Supply 1 MW of reserve power from another power supply facility (eg, backup substation) , (5) 'close circuit breaker C1 is closed (energized) to supply 4 MW of power from power supply system C; (3)' breaker B1 is closed (energized) to supply 5 MW of power from power supply system B The recovery operation is performed in the order of, and is different from the procedure of the recommended recovery operation ((1) to (6) in FIGS. 3 and 4) related to the electric accident of the power plant (power source A). Therefore, as shown in FIG. 5 (b), the training result of the trainer is based on the high score area (20 points), low score area (10 points), and other areas (0 points) in FIG. A predetermined score is given to each operation from the trainee's recovery operations (2) ′ to (6) ′, resulting in 70 points. According to the training evaluation result of the trainer in FIG. 5 (b), after 10 minutes after the third recovery operation (4) ′, the supply disturbing power achieved by the trainee is related to the recommended recovery operation. Therefore, it is understood that the trainee had performed a recovery operation different from the recommended recovery operation after the procedure of at least the third recovery operation (4) ′ (after 10 minutes). Further, a mistake in the recovery operation procedure can be easily grasped by comparing the recovery operation procedure of the trainee in the data collection unit 3 and the recommended recovery operation procedure in the scoring data storage unit 4.

  As mentioned above, according to the training evaluation apparatus 2 which concerns on 1st embodiment, since the data collection part 3 is provided, while the information regarding recovery operation which the trainee performed with the simulator 7 can be collected from the simulator 7, a scoring data storage part 4 is provided, and as a training evaluation standard, scoring data based on a recommended restoration operation for a predetermined electrical accident can be stored, and since an evaluation unit 5 is provided, a data collecting unit is provided based on the scoring data. By scoring the information regarding the recovery operation of the 3 trainees, the recovery operation training carried out by the trainee can be evaluated objectively and automatically. Further, the result of the training evaluation is displayed on the display unit 6 by superimposing information on the recovery operation of the trainee on the plotted scoring data, and the recovery operation training performed by the trainer is scored (in this embodiment, Therefore, it can be said that it is easy for the trainer to understand. Therefore, the trainer can clarify the problems and issues of his / her recovery operation by comparing the results of his / her training evaluation and the recommended recovery operation, and can fully utilize the results of the training thereafter.

  Next, second to fourth embodiments of the training evaluation apparatus according to the present invention will be described with reference to the drawings. The training evaluation devices according to the second to fourth embodiments each provide a predetermined violation monitoring function (instructed to stop the restoration operation to the simulator 7 when a violation operation that results in a violation that deviates from the rules, rules, etc.) It differs from the training evaluation apparatus 2 of 1st embodiment by the point provided with a function. FIG. 6 is a block diagram of the training evaluation apparatus according to the second to fourth embodiments. As shown in FIG. 6, the training evaluation device 2A according to the second to fourth embodiments is a violation act monitoring unit having a predetermined violation act monitoring function in the training evaluation device 2 according to the first embodiment shown in FIG. 2. 52 is provided in the evaluation unit 5A. When the violation monitoring unit 52 recognizes a violation operation that is a predetermined violation in the information related to the recovery operation of the trainee transmitted from the data collection unit 3, the violation monitoring unit 52 On the other hand, an instruction to stop the training simulation is issued, and the recovery operation by the trainee is stopped.

  Hereinafter, a second embodiment of the training evaluation apparatus according to the present invention will be described. Fig.7 (a) shows the single wire connection figure of the normal state of the training object area which concerns on the embodiment, FIG.7 (b) shows the state figure at the time of the electrical accident in the transformer H1 of (a). FIG. 8 shows a recovery flowchart of the electrical accident. FIG. 9 shows a diagram of scoring data related to the recovery operation of the electrical accident.

  The training evaluation apparatus 2A according to the present embodiment is a trial charging of the transformer H1 (experimental charging when an abnormality occurs in the transformer due to an electrical accident or the like, and the transformer is stopped and then restarted. The violation monitoring unit 52 having a violation monitoring function for issuing an instruction to stop the recovery operation of the trainer to the simulator 7 when the violation operation which is a violation related to) is monitored. Is provided in the evaluation unit 5 of the training evaluation device 2 of the first embodiment.

  As shown in FIG. 7A, in the training target area according to the present embodiment, a 110 kv bus and a 6 kv bus are connected via a transformer H1, and a primary circuit breaker is connected to the 110 kv bus of the transformer H1. A secondary breaker X2 is provided on the X1 and 6 kv bus side, and four distribution lines are arranged from the 6 kv bus line. Each distribution line is provided with a distribution line breaker Y1, Y2, Y3, Y4.

  Next, training evaluation using the training evaluation apparatus 2A according to the present embodiment will be described. In the present embodiment, an electrical accident of the transformer H1 shown in FIG. 7B is simulated by the simulator 7, and training evaluation for the restoration is performed. As shown in FIG. 7B, the primary and secondary circuit breakers X1 and X2 and the distribution line circuit breakers Y1 to Y4 are opened (cut off) by an electrical accident of the transformer H1.

  As shown in FIG. 8, the recovery flow for the electrical accident of the transformer H1 according to this embodiment is that the electrical accident of the transformer H1 occurs in Step 1, and the primary and secondary circuit breakers X1 and X2 are automatically shut off ( Open operation). In step 2, the distribution line breakers (distribution line breakers Y1 to Y4) are automatically cut off (opening operation). In Step 3, the trainer checks whether or not a failure element is displayed on the failure display of the transformer H1. Specifically, the confirmation is made on the basis of a failure element (failure cause) displayed on the transformer H1, and if no failure element is displayed, confirmation of the transformer H1 is not required locally. On the other hand, if the transformer H1 can be trial-charged, and if a fault element is displayed, it is necessary to test the transformer H1 after confirming the transformer H1 and eliminating the fault element on site. In other words, when a failure element is displayed on the failure display, if the state of the transformer H1 is not confirmed locally and a trial charge is performed, it is a violation. For example, when a serious failure and a short circuit are displayed on the failure display, if the state of the transformer H1 is not checked locally and a trial charge is performed, a violation occurs. If no failure element is displayed (No in step 3) as a result of confirmation of the failure display in step 3, step 4 is performed. If a failure element is displayed (Yes in step 3), step 9 is performed. .

  In step 4, the primary circuit breaker X1 is closed (energized), and a trial charging operation of the transformer H1 is performed. After the trial charging, the distribution line breaker Y1 is closed (energized) in step 5, the distribution line breaker Y2 is closed (energized) in step 6, and the distribution line breaker Y3 is closed (energized) in step 7. ) In step 8, when the distribution circuit breaker Y4 is closed (energized), the supply hindrance power accompanying the electrical accident of the transformer H1 becomes zero, and the electrical accident related to the transformer H1 is restored.

  In Step 9, the primary circuit breaker X1 is closed (energized), and the trial charging operation of the transformer H1 is performed, or the primary circuit breaker X1 is opened (cut off) and the test of the transformer H1 is performed. Decide whether to perform the charging operation. If the trial charging operation of the transformer H1 is carried out in step 9, the trial charging violation action of the transformer H1 is performed in step 10 (although the fault element is displayed in the fault display of the transformer H1) The act of charging is transmitted to the simulator 7 and the simulator 7 stops the training simulation related to the transformer H1 accident. Then, in step 11, the voice guidance “Training is suspended due to a violation operation act” by the voice function of the simulator 7 is executed. On the other hand, if the trial charging operation of the transformer H1 is not performed in step 9, the process returns to step 3 to confirm the failure display again. The repeated execution of Step 3 (Yes) and Step 9 (No) is such that the failure element is not displayed on the failure display by, for example, the state confirmation / inspection / repair of the local transformer H1 by the trainee (in Step 3). No), that is, depending on whether the cause of the failure of the transformer H1 is eliminated or whether the trial charge of the transformer H1 is performed even though the failure element is displayed in the failure display (Yes in step 9) Is terminated.

  The restoration operation training performed by the trainee is evaluated for the electrical accident of the transformer H1 restored by the restoration flow as described above. Specifically, first, the trainer simulates an electrical accident of the transformer H1 with the simulator 7. After the simulation, the distribution line breakers Y1 to Y4 of the distribution line arranged from the 6 kv bus are virtually opened (cut off) and supplied from the 110 kv bus through the transformer H1 to each distribution line. Power is virtually cut off. Subsequently, the trainer performs a restoration operation with respect to the electrical accident of the transformer H1 with the simulator 7, and information regarding the restoration operation is sent from the simulator 7 to the data collection unit 3 at a predetermined time interval (or each operation). The data collection unit 3 transmits the data to the evaluation unit 5A. At this time, when the violation monitoring unit 52 in the evaluation unit 5A recognizes a violation operation that is a violation related to the trial charging of the transformer H1, it instructs the simulator 7 to stop the restoration operation, and performs a training simulation of the simulator 7 By canceling, the recovery operation performed by the trainee is stopped. On the other hand, the trainer selects the scoring data from the scoring data storage unit 4 by the recommended restoration operation related to the electrical accident of the transformer H1, or when the electrical accident of the transformer H1 is simulated by the simulator 7, the scoring data Scoring data based on the recommended restoration operation corresponding to the electrical accident of the transformer H1 is automatically selected from the storage unit 4. Then, the scoring data selected by the trainer or mechanically automatically selected is transmitted to the evaluation unit 5A.

Here, the recommended restoration operation related to the electrical accident of the transformer H1 is based on steps 1 to 8 (No is selected in step 3) of FIG. (1) to (7) of the following procedure.
(1) Transformer H1 accident occurrence and primary and secondary circuit breakers X1 and X2 are automatically shut off (opening operation) (step 1 in FIG. 8)
(2) Automatic disconnection (opening operation) opening operation of distribution line circuit breakers Y1-Y4 (step 2 in FIG. 8)
(3) After confirming that there is no failure display of the transformer H1 (No in step 3 in FIG. 8), the primary circuit breaker X1 is closed (energized) and the trial charging operation of the transformer H1 is performed (FIG. 8). Step 4)
(4) Closing operation (energization) of distribution line circuit breaker Y1 (step 5 in FIG. 8)
(5) Closing operation (energization) of distribution line circuit breaker Y2 (step 6 in FIG. 8)
(6) Distribution line breaker Y3 is closed (energization) (step 7 in FIG. 8)
(7) Distribution line circuit breaker Y4 is closed (energization) (step 8 in FIG. 8)

  The information and scoring data related to the recovery operation by the trainee transmitted to the evaluation unit 5A is scored by the evaluation calculation unit 51 of the evaluation unit 5A based on the score attached to the scoring data shown in FIG. As can be seen from FIG. 9, if the trainee performs the same operation as the recommended restoration operation ((1) to (7) in FIG. 9), (2) to (7) in FIG. 100/6 points are given to each of the six restoration operations, and as a result, the training evaluation of the trainer is 100 points (100/6 points × 6). On the other hand, it is a violation operation that is an offense related to the trial charging of the transformer H1, and for example, if a fault element is displayed in the fault display of the transformer H1, but the trial charging is performed, the violation Based on the recovery operation performed by the trainer up to the point of operation, the trainee is evaluated for training.

  As described above, according to the training evaluation apparatus 2A according to the second embodiment, not only the training evaluation of the electrical accident recovery operation of the transformer H1, but also the training evaluation considering the violation related to the trial charging of the transformer H1. Can do.

  Next, a third embodiment of the training evaluation apparatus according to the present invention will be described. FIG. 10A shows a single-wire connection diagram in a normal state with respect to the training target area according to the embodiment, FIG. 10B shows a single-wire connection diagram at the time of an electrical accident in the transformer H3 in FIG. ) Is a single-line diagram at the time of recovery from the electrical accident. FIG. 11 is a recovery flow diagram of the electric accident, FIG. 12 (a) is an explanatory diagram of the transformer overload operation, and FIG. 12 (b) is a transformer overload violation act. It is explanatory drawing of the condition which deviated from overload driving | operation. FIG. 13 is a diagram of scoring data related to the recovery operation of the electrical accident.

  The training evaluation device 2A according to the present embodiment monitors a violation operation that becomes an overload violation act on the transformer, and instructs the simulator 7 to stop the recovery operation of the trainer when the violation operation is performed. A violation act monitoring unit 52 having a violation act monitoring function for issuing the above is provided in the evaluation unit 5 of the training evaluation device 2 of the first embodiment.

  In the training target area according to the present embodiment, as shown in FIG. 10A, a 110 kv bus and a 6 kv bus are arranged in parallel, and two transformers are provided between both buses. One is a transformer H2 (rated capacity of 10 MW) that supplies power of 8 MW, and the other is a transformer H3 (rated capacity of 10 MW) that supplies power of 7 MW, and 110 kv of the transformers H2 and H3. Are provided with a primary circuit breaker on the bus side and a secondary circuit breaker on the 6 kv bus side. Further, from the 6 kv bus, three distribution lines supplied by the transformer H2 and three distribution lines supplied by the transformer H3 are arranged. The former three distribution lines and the latter At the position on the 6 kv bus that separates the three distribution lines, the bus breaker Y11 is always provided in an open state (cut off state), and each distribution line arranged from the 6 kv bus has a distribution line break. Containers Y5 to Y10 are respectively provided.

  Next, training evaluation using the training evaluation apparatus 2A according to the present embodiment will be described. In this embodiment, an electrical accident of the transformer H3 shown in FIG. 10B is simulated, and training evaluation for the recovery is performed. As shown in FIG. 10B, the primary and secondary circuit breakers X3 and X4 and the distribution line circuit breakers Y8 to Y10 are in an open state (breaking state) due to an electrical accident of the transformer H3.

  As shown in FIG. 10 (c), recovery from the electrical accident of the transformer H3 is performed by the bus breaker Y11 so that the distribution line that has been supplied with power by the transformer H3 is supplied with power even after the accident. Is closed (energized), the amount of power supplied by the transformer H3 is added to the transformer H2, and a load is applied to the transformer H2, while temporarily supplying power to all six distribution lines without excess or deficiency. Do. And if the electrical accident of the transformer H3 recovers, it will return to the normal state of Fig.10 (a).

  As shown in FIG. 11, the recovery flow of such an electrical accident in the transformer H3 is as follows. In Step 12, an electrical accident occurs in the transformer H3, and the primary and secondary circuit breakers X3 and X4 are automatically shut off (opening operation). In step 13, distribution line breakers Y8 to Y10 are automatically cut off (opening operation), and in step 14, 6 kv bus breaker Y11 is closed (energized). In step 15, 7 MW supplied by the transformer H 3 is added to the transformer H 2 to which 8 MW is supplied, and a total of 15 MW is supplied to the transformer H 2. At this time, since the transformer H2 has a rated capacity of 10 MW, when 15 MW is supplied, an overload operation of 150% is performed. In step 16, the violation monitoring unit 52 confirms whether or not the transformer H2 is overloaded based on FIG. For example, as shown in FIG. 12 (a), the operation of a transformer with a load of 150% is recommended for 10 minutes, and the operation of a transformer with a load of 140% is recommended for operation within 50 minutes. As shown, an overload violation occurs when driving beyond the specified operating time of each load, or when driving over a maximum overload of 150%. In the confirmation of the presence or absence of overload operation of the transformer H2 in step 16, if the maximum overload exceeds 150% (Yes in step 16), the simulator indicates that there was an overload violation act in step 17. 7, the simulation for training of the simulator 7 is stopped, the recovery operation is canceled by the voice guidance of the simulator 7, and the recovery operation is stopped. On the other hand, if the maximum overload 150% is not exceeded (No in step 16), step 18 is performed. In step 18, distribution line breaker Y8, in step 19, distribution line breaker Y9, and in step 20, distribution line breaker Y10 is closed (energized), and 7 MW originally supplied by transformer H3 Power supply. In step 21, the transformer H3 is restored, the power supplied to the transformer H2 is set to 8 MW, and the 6 kv bus breaker Y11 is opened (shut off). In step 22, the violation monitoring unit 52 confirms whether or not the transformer H2 is overloaded. At this time, if the operation of the transformer H2 in the state of 150% load (time spent for the recovery operation from step 15 to step 21) is over 10 minutes (No in step 22), in step 23 The fact that there has been an overload violation is transmitted to the simulator 7, and the simulation for training of the simulator 7 is stopped, and if it is within 10 minutes (Yes in step 22), the restoration related to the transformer H3 accident is properly It ends as it was made.

  The restoration operation training performed by the trainee is evaluated for the electrical accident of the transformer H3 restored by the restoration flow as described above. Specifically, first, the trainer simulates an electrical accident of the transformer H3 with the simulator 7. After the simulation, the distribution line breakers Y8 to Y10 are virtually opened (cut off), and the power supply to the distribution lines to which the transformer H3 is supplying power is virtually cut off. Subsequently, for an electrical accident of the transformer H3, the trainer performs a restoration operation with the simulator 7, and information regarding the restoration operation is sent from the simulator 7 to the data collecting unit 3 at predetermined time intervals (or each operation). The data collection unit 3 transmits the data to the evaluation unit 5A. In addition, when the violation monitoring unit 52 in the evaluation unit 5A recognizes a violation operation that causes an overload violation of the transformer, the violation monitoring unit 52 instructs the simulator 7 to stop the restoration operation and stops the simulator 7 training simulation. , Stop the recovery operation performed by the trainee. On the other hand, the trainer selects the scoring data based on the recommended restoration operation related to the electrical accident of the transformer H3 from the scoring data storage unit 4, or when the electrical accident of the transformer H3 is simulated by the simulator 7 From the data storage unit 4, the scoring data by the recommended restoration operation related to the electrical accident of the transformer H3 is automatically selected. Then, the scoring data selected by the trainer or mechanically automatically selected is transmitted to the evaluation unit 5A.

Here, the recommended restoration operation related to the electrical accident of the transformer H3 is based on Steps 12 to 22 in FIG. 11 (No in Step 16 and Yes in Step 22), and (1) to (8) in FIG. It consists of the following procedures.
(1) Transformer H3 accident occurrence and primary and secondary circuit breakers X3 and X4 are automatically shut off (opening operation) (step 12 in FIG. 11)
(2) Automatic disconnection (opening operation) of distribution line circuit breakers Y8 to Y10 (step 13 in FIG. 11)
(3) 6 kv busbar breaker Y11 is closed (energized) (step 14 in FIG. 11)
(4) Supply 15 MW to the transformer H2 (overload rate 150%) (step 15 in FIG. 11), and at this time, the violation monitoring unit 52 confirms the presence or absence of the transformer overload operation (step 16 in FIG. 11).
(5) Distribution line circuit breaker Y8 is closed (energization) (step 18 in FIG. 11)
(6) Distribution line breaker Y9 is closed (energization) (step 19 in FIG. 11)
(7) Distribution line circuit breaker Y10 is closed (energization) (step 20 in FIG. 11)
(8) Restore the transformer H3, return the transformer H2 to the supply of 8 MW, and open (break) the 6 kv busbar breaker Y11 (step 21 in FIG. 11). At this time, presence or absence of transformer overload operation Is confirmed by the violation monitoring unit 52 (step 22 in FIG. 11).

  Information relating to the restoration operation by the trainee and the scoring data transmitted to the evaluation unit 5A is scored and evaluated based on the score attached to the scoring data shown in FIG. 13 by the evaluation calculation unit 51 of the evaluation unit 5A. As can be seen from FIG. 13, if the trainee performs the same operation as the recommended restoration operation ((1) to (8) in FIG. 13), (2) to (8) in FIG. 100/7 points are given to each of the seven restoration operations, and as a result, the training evaluation of the trainer is 100 points (100/7 points × 7). On the other hand, it is a violation operation that becomes an overload violation act of the transformer, for example, when a load is applied to the transformer and the operation is performed exceeding the specified overload time, the time when the specified overload time is exceeded Based on the recovery operations performed by the trainer so far, the trainer's training evaluation is made.

  As described above, according to the training evaluation device 2A according to the third embodiment, it is possible to perform not only the training evaluation of the electrical accident recovery operation of the transformer H3 but also the training evaluation considering the overload violation act of the transformer H3. .

  Next, a fourth embodiment of the training evaluation apparatus according to the present invention will be described. FIG. 14A is a connection diagram of a normal state between the electric power systems according to the embodiment, FIG. 14B is a loop power flow situation of the communication line A, and FIG. 14C is a loop power flow situation of the communication line B. . Moreover, FIG. 15 shows the restoration flowchart of the electric accident in the electric power system which concerns on the embodiment.

  The training evaluation device 2A according to the present embodiment monitors a violation operation that causes an excess in equipment capacity associated with a loop power flow (a power flow superimposed on a power flow before the power system change) during a power system change (loop operation). When the violation operation is performed, the violation monitoring unit 52 having the violation monitoring function (tidal current monitoring function) for issuing an instruction to stop the recovery operation of the trainer to the simulator 7 is evaluated by the training evaluation of the first embodiment. The evaluation unit 5 of the device 2 is provided and configured.

  In the training target area according to the present embodiment, the power system A and the power system B are connected by the communication line A and the communication line B as shown in FIG. The installation capacity of the communication line A is 108A, the installation capacity of the connection line B is 216A, both connection lines are always open (cut-off state), and are closed (energized) in an emergency such as an electrical accident. Become.

  The electrical accident and its recovery flow according to the present embodiment are, for example, a simulation of an electrical accident in the electric power system B, and in the case where the power supply trouble caused by the electric accident cannot be solved only in the electric power system B, the electric power system A power supply corresponding to a predetermined supply hindering power from A (power shortage due to an electric accident in the electric power system B) is temporarily supplied to the electric power system B, and an electric accident in the electric power system B is restored (electric power Power supply from system B is eliminated), and power supply from power system A to B is cut off. Specifically, when an electric accident in the electric power system B is simulated by the trainer, as shown in FIG. 15, in step 24, an electric accident occurs in the electric power system B, and in step 25, the trainer Alternatively, power supply (loop operation) corresponding to insufficient power in the power system B is performed from the power system A to the power system B using the communication line B. Then, in step 26, the violation monitoring unit 52 confirms whether or not the current (loop current and load current) considering the loop power has exceeded the facility capacity of the connection line used during the loop operation. At this time, if the current considering the loop power flow does not exceed the facility capacity of the connecting line used during the loop operation (No in step 26), the training simulation is continued. In step 27, the trainer If the electric accident in the system B is recovered and the connection line used at the time of the loop operation is opened (cut off), while the current exceeds the capacity of the connection line (Yes in step 26), in step 28 The simulator 7 is instructed to cancel the recovery operation from the violation act monitoring unit 52, and the simulator 7 stops the simulation for training and notifies the user that the recovery operation is stopped by voice guidance. More specifically, when the current taking into account the loop power flow, which is caused by the power supply from the power system A to the power system B, is set to 200A, for example, the circuit breaker Y12 is closed as shown in FIG. (Energized) and the circuit breaker Y13 is opened (cut off), so that if the communication line A is used, the facility capacity (108A) of the communication line A will be exceeded. 52, the training simulation is stopped and the restoration operation stop is notified by voice guidance. On the other hand, if the connection line B is used by opening (breaking) the breaker Y12 and closing (energizing) the breaker Y13 as shown in FIG. Since it falls within the range of the capacity (216A), violations can be avoided, a current of 200A can be passed from the power system A to B, and the recovery operation is continued. And in the training evaluation, if the restoration operation is properly completed without the current between the grids exceeding the capacity of the connection line, the scoring data by the recommended restoration operation corresponding to the electric accident of the power system B Based on this, the training evaluation of the recovery operation training performed by the trainee is made, but if it exceeds, the training evaluation is performed based on the recovery operation performed by the trainer up to the time of the excess.

  According to such a training evaluation apparatus 2A according to the fourth embodiment, it is possible to perform training evaluation in consideration of a violation act that causes an excess of the equipment capacity due to the loop power flow at the time of power system change (loop operation). .

  In addition, in the power flow monitoring function at the time of loop operation, in addition to stopping the recovery operation due to the excess of the capacity of the connection line described above, the recovery operation is also canceled due to an illegal act on the angle (phase difference between current and voltage). . Specifically, when an operation that exceeds the specified range for the angle at the time of system change (loop operation) is performed, the simulation for training is stopped, a voice notification that the recovery operation is stopped is given, and the recovery operation is canceled. Is done. For example, when the angle is always set to be within 15 degrees in the + and-directions, and within 30 degrees in the + and-directions in an emergency such as an electrical accident, the loop operation performed at the time of the electrical accident If the angle exceeds 30 degrees in the + direction or the − direction, the restoration operation is stopped. On the other hand, if the angle is within 30 degrees in the + direction and the − direction, the restoration operation is continued. Therefore, it is possible to perform a training evaluation in consideration of a violation act that causes an angle excess due to the loop current.

  Further, in the training evaluation device 2A according to the second to fourth embodiments, the function is enabled (monitored) without always enabling (executing) each predetermined violation monitoring function in the violation monitoring unit 52. The function may be switched to a state in which the function is executed) or disabled (a state in which the monitoring function is not executed).

  Further, in the first to fourth embodiments, the simulator 7 has the same or similar function as the actual machine in the control station 1, even if it is not an actual machine in the control station 1, and is an independent device from the actual machine in the control station 1. It may be. In addition, a trainer can perform the act of the trainer as an alternative. In this case, the trainer can train alone. Further, the provision of the predetermined score in the scoring data is not limited to the three areas such as the high scoring area, and for example, the predetermined score may be provided in two areas and four areas.
