Abstract
PURPOSE: To stably control lead phase and lag phase reactive power by using a simple control circuit consisting of only the one DC motor when a thyristor phase is controlled.
CONSTITUTION: The size of the output signal QF of the reactive power detection section 9 is proportional to that of reactive power. A reactive power reference signal generator 10 generates the reference signal Qr of which polarity is reverse with that of the output signal of the reactive power detection section 9. The adder section 11 adds the signals QF and Qr. The proportional arithmetic section 12 doubles the output of the added section 11. |The substracter 13 finds the remainder between the output εI of the proportional arithmetic section 12 and the signal QF. The switching section 14 selects whether the output of the reactive power detection section 9 is used or that of the subtracter 13 is used as the feedback signal QFO at lead phase control and lag phase control. At lead phase control, the output QF of the reactive power detection section 9 is used as the reactive power feedback signal QFO and at lag phase control, the output QF, of te subtracter 13 is used.
