| Abstract |
The usual instantaneous reactive power q has been defined by using a,B components of the voltage and current. The current from the power source contains higher harmonic components when q is used for the control method of an active power filter in unsymmetrical
three-phase three-wire system. The higher harmonic current components are bad for telecommwlication and so on. Therefore. the authors have defined a new instantaneous reactive power whose mean value is equal to the three phase reactive power. By the use of this value. the authors have clarified a new calculation method for compensating current command which solves the defects of the conventional pq method. Lastly, the authors have given the
calculation method of compensating current command in the three-phase four-wire system. |
