【Abstract】 A prototype of series hybrid active power filter (SHAPF) applied to three-phase four-wire electric distribution systems is studied and developed. The principle of fundamental current control is adopted and the effect of harmonic currents generated by nonlinear loads on power system is reduced significantly. Experimental equipment controlled by DSP achieves realtime calculation and control. Experimental results show that the equipment provides excellent filtering performance.更多还原
