PURPOSE:To smoothly improve a power factor by calculating the power generation allowable reactive power range and the generator reactive power controlled variable in accordance with the power factor of a generator and not only controlling increase/reduction of the generator reactive power in accordance with the controlled variable but also monitoring it by a display means. CONSTITUTION:An allowable power factor calculating means 3A calculates the allowable reception power factor, and an allowable reception VAR range calculating means 5a calculates the allowable reception reactive power range. An adjustment requiring VAR value calculating means 7A calculates a reactive power value requiring adjustment, and a reception power factor calculating means 12 calculates the reception power factor. The power factor of the generator is calculated by a means 2 to calculate the power generation allowable reactive power range by a power generation allowable VAR range calculating means 26, and a power generation increasable VAR value calculating means 27 calculates the power generation increasable reactive power value, and a power generation reducable VAR value calculating means 28 calculates the power generation reducable reactrive power value. A power generation VAR increase controlled variable calculating means 29 calculates the power generation reactive power increasing controlled variable, and a power generation VAR reduction controlled variable calculating means 31 calculates the power generation reactive power reduction controlled variable, and a AVR increase control command output means 33 outputs the power generation reactive power increase control command and an AVR reduction control command output means 34 outputs the power generation reactive power reduction control command to control increase/reduction of the generator reactive power, and the control state is always monitored by a display means 35. |
