In step S3, the generator output and load values of the system connected by the restoration route determined in step S2 are determined. Step S4
Then, a countermeasure in the case where an overload exists and a review of the restoration route based on the overload countermeasure are performed. In step S5, an operation procedure necessary for the single system in parallel is created. In step S6, it is determined from the phase difference between both ends of the switch to be switched whether loop switching or power failure switching, and a switching operation procedure in a healthy system is created. In step S7, the recovery operation procedures obtained in steps S1 to S6 are compiled, a final accident recovery operation procedure taking into account the supply and demand balance is created, and the process is terminated. The accident recovery operation procedure obtained as in the above example is stored in the accident recovery operation procedure storage means 3.

After the training is completed, the trainee requests a model procedure presentation from the trainee man-machine device 5.

The accident recovery operation procedure input means 4 retrieves the accident recovery operation procedure stored in the accident recovery operation procedure storage means 3, converts it into the same data format as the operation from the trainee or trainer, and inputs it to the operation / setting data storage means 8. I do. The power system response simulation means 9 extracts the accident recovery operation procedure data input to the operation / setting data storage means 8 by the accident recovery operation procedure input means 4 and simulates the response of the power system in the same manner as the operation from the trainee or trainer. Then, the resulting SV data and TM data are stored in the power system simulation data storage unit 10.
