PROBLEM TO BE SOLVED: To prevent a state from getting worse due to a calculation error, by judging the state of a current power distribution system before calculating power flow, and by preventing execution of calculation processing when the state is appropriate. SOLUTION: Before calculating power flow, system information and the detection data of a target system are inputted and stored (S1), and the presence or absence of a place that deviates from the adjustment tolerance and prescribed voltage width of a local device is confirmed according to the detection data (S2). Furthermore, it is judged whether there is no tolerance or a deviation place exists according to the detection data (S3), reactive power in each detection place is increased in the case of NO or it is judged whether the minimum voltage value is not reached or not (S4), and no adjustment is required for preventing calculation processing from being executed in the case of NO. On the other hand, in the case of YES, the degree of appropriateness of a current state for a target voltage and the reactive power is judged (S5), at the same time, it is judged whether the current state is appropriate or not (S6), and no adjustment is required for preventing the calculation processing from being executed in the appropriate case. In the inappropriate case, a target local device is determined (S7) and the calculation processing is started. |
