PURPOSE:To accurately and easily recognize the weakest points of a system, control countermeasures and system condition after countermeasures are made without any complicated operation of man-machine equipment performed by an operator, by automatically selecting the most unstable point of current system condition and an adjustment method for effective phase modification equipment to display them CONSTITUTION:A maximum effect phase modification selection means 7 automatically selects the most unstable point and a phase modification equipment providing the maximum effect with respect to the most unstable point from a file 4 for storing a voltage stability monitoring index periodically computed with respect to a current power system condition and also a file 6 for storing an amount of modification effect to store it into a maximum effect modification plan data 8. Next, an after-adjustment tide computing means 9 adjusts a selected phase modification equipment and then the tide computation for system condition is performed to store it into an after-adjustment system storage file 10. A voltage stability countermeasure adjustment result display means 11 displays the after-adjustment system condition, the most unstability point and the maximum effect phase modification equipment in a display device 12. |
