Title: Automatic control method for capacitor
Inventor: FUJITA TSUTOMU
IPC: H02J3/18
Filed: 1985-06-24
Abstract: PURPOSE:To prevent a hunting phenomenon of control by performing the automatic control of a capacitor after deciding whether or not the estimated reactive power and the estimated power factor set after control are kept under a set level only when said reactive power and power factor are different from the present polarity. CONSTITUTION:A phase advance capacitor 17 which improves the power factor of a power system is connected to the power system via a switch 18 which is controlled by a control computer 11. The computer 11 is provided with a central processor CPU12 for various arithmetic processes and a process input/ output device PI/O13. Then the power and the reactive power of the power system are supplied by a power converter 15 and a reactive power converter 16 via the PI/O13. Then the reactive power and the power factor of the power system are compared with the set values at the phase delay and advance sides respectively. It is decided whether or not said reactive power and power factor are kept under a set level only when these reactive power and power factor are different from the present polarity. Thus the capacitor 17 is controlled automatically.
