Here, if an overload occurs, it is determined in step 158 whether there is a single block. If there is a single block, the process ends. If not, the process returns to step 155 to determine whether there is a thermal power generator. If it is determined in step 155 that there is no thermal power generator, or if it is determined in step 157 that a thermal power generator is present, a parallel operation with a healthy system is performed and no overload occurs in the parallel operation, At 159,
A determination is made whether there is a hydro generator. Here, if there is a hydroelectric generator, it is determined whether there is a single block in step 158 after disconnecting the hydroelectric generator in step 160, but it is determined in step 159 that there is no hydroelectric generator. Then step 1
Step 58 is performed.

Upon completion of the single system cancellation system creation processing shown in FIG. 36, it is determined whether or not there is a cancellation procedure shown in step 103 shown in FIG. If it is determined that there is a solution procedure, then in step 104 the parallel operation is preferentially selected in the solution procedure, and it is determined in step 105 whether there is a single block.
The information acquisition processing of the single block shown in FIG. 1 is performed, and if not, the single system cancellation processing of FIG. 35 ends.
If it is determined in step 03 that there is no solution procedure, a recovery policy unknown is output in step 106, and the single system solution process ends.

FIG. 46 is a diagram showing the pre-accident system, the post-accident system, and the restoration target system. In the system before the accident shown in FIG. , The circuit breaker at the substation K side of the transmission line L is cut off. It is assumed that the circuit breaker on the electric substation K side of the transmission line X is cut off for some reason, and the electric substation S is out of power. In this case, since the transmission line X side is normal, the restoration target system only needs to be in the state shown in (c), and for that purpose, the circuit breaker at the substation K side of the transmission line X should be turned on. Therefore, in this case, as shown in FIG. 47, it is sufficient that the electric station S cuts off the circuit breaker of the transmission line L in order to eliminate an accident point, and the electric station K inserts a circuit breaker of the transmission line X for load transmission. Since the display is performed by this device, the operator only has to judge whether or not the display content is sufficient.

Second Embodiment FIG. 2 is a block diagram showing a second embodiment, in which an automatically created restoration procedure can be directly modified by a restoration procedure modifying means 409 by an operator. In this example, in accordance with the restoration procedure created by the restoration procedure creation unit 405, the restoration final system creation unit 404 creates a restoration final system as a recovery target based on the power system data, and converts this in the form of a power system diagram or the like. It is displayed on the CRT device 5. The used recovery procedure is also displayed in another display area of the CRT device 5 in the form of a list or the like. At this time, a multi-window or the like may be used, and FIG. 24 shows a display example thereof. The operator looks at this restoration final system and the restoration procedure, makes a quality judgment and evaluates equipment overload, etc., and if necessary, uses the restoration procedure correction means 409 via the manual input device 6 based on the result. Modify the desired recovery procedure directly. The restoration final system is re-created based on the restoration procedure thus modified, and is updated and displayed on the CRT device 5 together with the restoration procedure.

According to the present embodiment, the recovery procedure can be directly modified by the operator, so that a recovery procedure close to an operation based on the experience and knowledge of the operator can be obtained. It is possible to create a more realistic final restoration system. Further, by modifying the restoration procedure, useless restoration operation can be omitted, so that it is possible to shorten the time required for completing the target restoration final system. In addition, since the experience and knowledge of the operator can be applied when modifying the recovery procedure, it is possible to supplement the recovery procedure creation knowledge stored in the apparatus. This makes it possible to eliminate in advance equipment overload during the creation of the final restoration system.

Third Embodiment FIG. 3 is a block diagram showing a third embodiment, in which a plurality of restoration procedures automatically created are directly corrected by an operator by a restoration final system multiple creation unit 410 and a recovery procedure multiple creation unit 411. It is an example that made it possible, displaying multiple recovery procedures,
It is modified as necessary while comparing and contrasting. In this example, in accordance with a plurality of restoration procedures created by the restoration procedure creation means 411, a plurality of restoration final systems are created by the restoration final system creation means 410 in accordance with each restoration procedure, and displayed on the CRT device 5 together with the restoration procedure. Is done. At this time, all the images may be displayed at once using a multi-window or the like, and FIG. 25 shows an example of the display. Performs acceptability determination and evaluating the plurality restoration final systems was compared operator, the results based on via the manual input device 6 using a recovery procedure correction means 40 9, and selects a recovery procedure that operator desires directly . The restoration final system is recreated based on the restoration procedure selected in this way, and is displayed on the CRT device 5 together with the corresponding restoration procedure. According to this embodiment, a plurality of restoration procedures are displayed at once, and the operator can compare and review these procedures, so that the restoration final system can be efficiently created. In addition, since a plurality of restoration procedures can be viewed and compared at the same time, the operator can apply the good points of each restoration procedure to another restoration procedure. If necessary, by leaving the previously created restoration procedure without modification, it is possible to compare the previously created restoration final system with the restoration last system recreated after modification.

Fourth Embodiment FIG. 4 is a block diagram showing a fourth embodiment, in which the restoration system constraint conditions are set by the restoration system initial constraint condition storage unit 412 and the restoration system initial constraint condition setting unit 413 before the creation of the restoration final system. By doing so, an optimal recovery procedure is created. In the first embodiment, the restoration procedure is changed by setting the ON / OFF of the system diagram switch by the operator, but in the present embodiment, the operator performs the setting before creating the final restoration system, The restoration final system taking the constraints into account is performed by the restoration final system creation unit 404, and the restoration procedure creation unit 405 creates a restoration procedure based on the restoration final system.

According to the present embodiment, since the operator always sets the optimal recovery constraint condition, a recovery procedure based on the recovery constraint condition corresponding to the occurred accident situation is created, and the optimal recovery procedure is created. This makes it unnecessary to change the recovery procedure. Further, since it is possible to create a recovery procedure under various recovery constraint conditions according to the setting of the operator, it is possible to create a recovery procedure under all the recovery procedure constraint conditions. Further, by presenting to the operator the manner in which the recovery procedure changes due to the change in the constraint condition, the operator can learn the ability to determine the optimal recovery procedure.

Fifth Embodiment FIG. 5 is a block diagram of a fifth embodiment, in which the constraints are stored in the restoration system constraint condition storage means 4 before the power system restoration final system is created.
14. Selection is made by the restoration system constraint condition setting / change means 415. In the fourth embodiment, the restoration system initial constraint is changed after the restoration procedure is created. However, before the restoration final system is created, the restoration system constraint condition setting / change unit 415 allows the operator to store the restoration system constraint. This is to set / change the means 414. Since the operator sets / changes the restoration system constraints before creating the final restoration system, the restoration procedure based on the constraints determined by the operator is created without re-creating the restoration procedure. A recovery procedure can be created.
