This paper presents an improved technique for the power quality of the electrical part of a wind generation system with a synchronous generator (SG). The main aim is to optimize the utilization of wind power injected into the grid. To realize this goal, an uncontrolled rectifier-digitally controlled inverter (URDCI) system is proposed. The advantage of the proposed system is its simplicity due to...
This article analyzes the principle of three-phase parallel active power filter and the detection method of harmonic. Then it introduces the main circuit of active power filter and the core control system of TMS320F2812 DSP and gives one kind of control policies to realize the entire compensation of reactive power and harmonic by the instantaneous power theory. The theoretical analysis and experimental...
This paper presents the design and implementation of a linear quadratic regulator (LQR) with integral action (LQRI) for a three-phase three-wire shunt active filter (SAF). The integral action is added so as to cancel the steady-state errors for reference tracking or disturbance rejection, knowing that the standard LQR provides only proportional gains. The controller is designed to achieve DC bus voltage...
