PURPOSE:To prevent an incorrect CB trip and an operation of a protective relay and to simulate an accurate accident affecting state of the same presence as an operation of a real system at a high speed by constituting to select a preset second accident sequence according to controlling condition. CONSTITUTION:A second accident sequence is previously set. In this case, a sequence NO 12 is selected according to a definition of presence/absence of a predetermined state change, second accident sequences 13-15 are set, and the sequences 13-15 are realigned in a time series sequence, and edited. When a second accident is detected, coincidence/discordance of a control condition is judged, and whether a time of the sequence which is realigned in a time series sequence is the same as a present time or not is judged. Then, if the sequence is a pattern having a state change presence, a sequence generating process is executed, but if the sequence is a pattern having no state change, the sequence is skipped to next sequence process. These processes are repeated until the sequence is finished. |
