Improving Compensation Performance in Three- Phase Active Power Line Conditioners by DC-Voltage Control

چکیده
This paper analyses the influence of the prescribed DC-link voltage on the filtering efficiency, in terms of current harmonic distortion after compensation, in a three-phase three-wire shunt active power line conditioner. The AC voltage controller as nonlinear load and two configurations of the coupling filter are taken into consideration. It is pointed out that, for each rms current to be compensated, there is an optimal set value of the DC-link voltage which minimizes the supply current distortion after compensation. Experimental tests validate the simulation results.

متن کاملA New Strategy for Simultaneous Compensation of Instantaneous Reactive Power and Harmonics of Non-Linear Loads (RESEARCH NOTE)
This paper presents a new control method for simultaneous compensation of instantaneous reactive power and current harmonics by parallel active filters (PAFs). Reference compensating currents of PAF are calculated using the subtraction of instantaneous power from its average value. In this way, it is possible omitting high/low pass filter(s) from the control circuit of PAF, which usually result...
