Abstract:
Power quality issues of wind-diesel hybrid systems have been discussed in this paper. Fixed pitch wind turbine
coupled with induction generator has been considered for this study. The rotor blade passing frequency effect has
been included in the wind turbine model. Dynamic response to random wind speed, voltage deviation due to
continuously varying load, reactive power limit is shown in the results. Effect of varying X/R ratios has also
been investigated on system voltage deviation.
1. INTRODUCTION The system shown in figure (1) is a typical wind-
diesel hybrid system. A fixed pitch wind turbine is
Wind energy offers the possibility of generating coupled with an induction generator through a gear

available from wind generator is variable due to generator (WTG) and diesel driven synchronous
fluctuating wind velocity.
