Control system for grid generation of a switched reluctance generator driven by a variable speed wind turbine

This paper presents a novel control system for the operation of a grid connected switched reluctance generator driven by a variable speed wind turbine. The SRG is connected to a power converter which is controlled to drive the wind energy conversion system (WECS) to the point of maximum aerodynamics efficiency using closed loop control of the power output. A second power converter, a vector controlled voltage source PWM inverter, is used to interface the machine to the grid. An experimental prototype was constructed in which the wind turbine was emulated by an induction machine drive. Experimental result obtained with this prototype are presented and discussed in this paper.
