Abstract: |
Renewable generation affects power quality due to its nonlinearity, since solar generation plants and wind power generators must be connected to the grid through high-power static PWM converters. This paper presents active power filter implemented with a four-leg voltage-source inverter. The main features of this control scheme is 1) To control power converter to inject power generated from RES to the grid, and 2)To act as a shunt APF to compensate current unbalance, load current harmonics, load reactive power demand and load neutral current. The compensation performance of the proposed active power filter and the associated control scheme under steady state and transient operating conditions is demonstrated through simulation results. In this paper the topology of three phase four leg inverter is shown along with its controlled on the basis of hysteresis control and SRF theory for current reference generation 3) The results are presented for both wind & solar type renewable power generation systems. |
