Abstract

hybrid-STATCOM for providing compensating reactive power required by a load, the hybrid-STATCOM comprising : a TCLC part for each electric power phase, each TCLC part comprising : a coupling inductor; a power filter capacitor; and a thyristor-controlled reactor connected in series with a power filter inductor; and an active inverter part comprising : a voltage source inverter for each electric power phase; and a DC-link capacitor connected in parallel with the voltage source inverters. The control strategy of the hybrid-STATCOM is separated into two parts : TCLC part control and Active inverter part control. The TCLC part control is based on the instantaneous pq theory and aims to compensate the loading reactive power with the controllable TCLC part impedance. The active inverter part control is based on the instantaneous active and reactive current id-iq method and aims to improve the overall performance of the hybrid-STATCOM under different voltage and current conditions.
