A Study on the 2nd Exitation for CVCF Generation of Doubly-fed Induction Generator

This paper deals with the control strategy for the constant voltage, constant frequency (CVCF) generation of doubly -fed induction generator. Since induction machine is a nonlinear and multivariable one, the influential factors for CVCF generation of induction generator are the magnitude of output voltage, load current and its power factor, slip of the machine, etc. To get appropriate control scheme and study the effect of its parameters, the control equation of induction machine is derived and tested. The simulation and test results show that suggested equation and control system are very useful strategy for the CVCF control of induction generator.
