This paper presents a new configuration for a wind energy conversion system (WECS) with variable speed, using a squirrel cage induction generator (SCIG) for standalone energy system applications. The Proposed configuration utilizes converters with reduced power rating, operates with MPPT to maximum wind energy extraction, uses battery bank for energy storage and can operate with non-linear and unbalanced loads. Energy storage characteristic is desirable for wind energy conversion systems isolated from the mains since an energy interruption does not stop of the entire system. Also, the power rating of the converters is reduced compared to the generator and load power rating due to the low power requirements of the power converters to SCIG excitation control and to supply the load. It is presented also the whole proposed WECS and the system operation modes according the turbine speed. It is presented also the whole proposed system and the system operation modes according the turbine speed. The simulation of the proposed WECS is performed in conjunction with the dynamic wind turbine model of 1 kW and the results confirm the effectiveness to supply unbalanced and non-linear loads, the converters power rating reduction and operation with variable turbine speed. Simulation results show the effectiveness of the system to supply unbalanced and non-linear stand alone loads.Index Terms -Wind energy conversion system, SCIG, stand-alone energy system, reduced converter power rating.

“…On the stand alone SCIG based system the generate voltage is strongly affected by the harmonic content of the load current [13]. In this context, the load side inverter can be used as a shunt active filter (SAF), satisfactorily reducing the load harmonics experienced by the generator [11].…”

“…Numerous papers in the researchers have attempted to analyze the SEIG using equivalent circuit approach. Two different methods of solution have been employed, namely, the loop impedance and the nodal admittance methods [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Steady-state analysis of such generators is of interest, both from the design and studying performance characteristic of SEIG.…”

“…The AC/DC converter used in Fig.1 can be classified into the three phase bridge rectifier. When the three phase bridge rectifier load is connected to the terminals of the SEIG the undesired problems caused by the harmonic currents such as additional power losses, high frequency pulsating torque, harmonic voltage distortion will occur in the SEIG [13]. The interest subject for this work is the study and performance analysis types of the SEIG with nonlinear loads.…”

This paper proposes the investigation on the performance between standard and high efficiency induction machines operating as SEIG feeding the nonlinear loads having same rating of 3 phase, 2.2 kW, 220/380 V, 4 poles. Consideration of capacitance for the SEIG based on equivalent circuit model under steady-state load conditions and a power flow diagram is given. The interpretation of experimental results can be guidelines for effective design and development of SEIG with DC supply for wind energy applications.
