Performance analysis for DFIG Feeding a Stand-alone Unbalanced Load
In this paper, a control system for the operation of a doubly fed induction generator (DFIG), feeding an unbalanced three-phase load is presented. The load unbalance is compensated using the front-end converter. The control system is based on positive and negative sequence components of current. MATLAB Simulation results obtained from a DFIG system and are presented and discussed in this paper....
متن کاملNonlinear Control for Positive Output Super Lift Luo Converter in Stand Alone Photovoltaic System
This paper proposes a stand-alone photovoltaic (PV) system based on a DC-DC positive output super lift Luo (POSLL) converter. A conventional sliding mode control, a sliding mode controller using a simple sign function and a linear controller using proportional integrator (PI) are used for the control of the PV panel voltage and POSLL converter inductor current and these methods are compared tog...
متن کاملA New Dead Time Compensation method for Stand - alone Inverter under Unbalanced Loads
phase stand-alone inverter is caused by unbalanced load and a dead time distorts inverter output voltage more unsymmetrically. When the inverter supplies unbalanced load, three phase output voltages include unbalanced odd harmonics but dq-axis voltages at synchronous reference frame have even harmonics with different magnitude each other. In this paper, a new compensation method is proposed to ...
متن کاملDesign of Single phase inverter using PID controller For nonlinear load application
The paper presents a single phase transformer based inverter for nonlinear load application using PID controller. A capacitive full bridge circuit is used to provide instant current under nonlinear load conditions and thereby reducing the harmonics. A new proportional plus integral controller for inverter control is proposed to eliminate the dc current component, and steady state error under he...
متن کاملAn Effective Rotor Current Controller for Unbalanced Stand-Alone DFIG Systems in the Rotor Reference Frame
This paper presents an effective rotor current controller for variable-speed stand-alone doubly fed induction generator (DFIG) systems feeding an unbalanced three-phase load. The proposed current controller is developed based on proportional plus two resonant regulators, which are tuned at the positive and negative slip frequencies and implemented in the rotor reference frame without decomposin...
