Selective Shunt Active Power Compensator in Four Wire Electrical Systems Using Symmetrical Components

Abstract: This article analyzes the inefficiencies present in four wire electrical systems where linear unbalanced loads are connected. The new reference currents are proposed for the selective compensation of the inefficiencies using a three-legs shunt active power converter. The positive-, negative-and zero-sequence components of voltages and currents in load terminals determine the compensating currents that cancel the inefficient power flows. A new method for the control of the voltage unbalances in the split DC bus… Show more

“…The following rows show the values obtained with the six CS. P 1 + is increased approximately in 250 W during SAPC operation because SAPC losses are compensated by means of three balanced fundamental positive-sequence active currents supplied by the power network [19]. The non-efficient currents are full, partial, or not compensated according to the scaling factors determined for each CS.…”

“…The proposed algorithm extends the work presented in [19] by means of the calculation of the scaling factors that, multiplied by the load non-efficient current terms, permit achieving the SAPC maximum capabilities. The SAPC control obtains the SAPC reference compensating currents based on IEEE Std.…”
