Contributions to the steady state analysis of wind-turbine driver

The paper makes the following three contributions: First, it presents a digital computer method of predicting the steady state performance of a self-excited induction generator for given speed, capacitance and load conditions along with results of validation studies on a laboratory machine, Secondly, a procedure is presented to check whether the operating point of a given uncontrolled wind-turbine driven self-excited induction generator set on load is a satisfactory point. Details of the resulting capability chart are discussed by application to a specific case. Finally, an experimental method of simulating wind-turbine drive characteristics is presented along with details of implementation of a laboratory set-up involving a d.c. dynanometer coupled to an induction generator.
