PROBLEM TO BE SOLVED: To provide a voltage stabilizer control method which can assure low cost and high control precision. SOLUTION: The capacities, required to cutoff the load and power capacitor, are determined within the target range in advance, in preparation at interruption time of transmission lines. In step 21 to 25, a load bus voltage VL and load power PL are checked if they are within the target range. If they are not, the require capacities for cutting off the load and power capacitor are newly calculated, so that they are within the target range in step 26 to 34. In case the transmission lines are interrupted, the cut off operation is carried out, on the basis of the result thus calculated in advance. |
