Abstract

This paper presents the implementation and design of a power converter for an autonomous wind self-excited induction generator (SEIG) feeding an isolated load through the employment of a DSP-based rectifier-inverter circuit. The output voltage and frequency of the studied wind SEIG is inherently variable due to random fluctuation of wind-speed variation. A three-phase constant-voltage constant-frequency voltage source is required to supply an isolated load via a designed power converter with pulse width modulation (PWM). This paper utilizes a three-phase induction machine model and a three-phase rectifier-inverter model based on a-b-c reference frame to simulate the performance of the studied generation system. The laboratory 2.2 kW (3 hp) induction motor driven by a brushless DC motor is employed to simulate the characteristics of a wind SEIG. Both simulated and experimental results of the studied system are compared to validate the proposed model. It can be concluded from the simulated and experimental results that the designed power converters with adequate control scheme can effectively improve the performance of output voltage and frequency of the studied SEIG feeding an isolated load.
