Build-Up Steady-State Analysis Of Wind-Driven Self-Excited Induction Generators

For the contradiction between the increasing importance of the application of induction generator in the new energy power generation such as wind energy and the relative laggard of research on its comprehensive performance, the build-up steady-state analysis is performed for the wind-driven self-excited induction generator system based on the unloaded transient equivalent circuits and its mathematic model of the self-excited induction generator (SEIG) in the two-phase stationary reference frame. So it obtains the buildup steady-state conditions represented by the unloaded transient mathematic model. On the basis of the result obtained for the build-up steady-state limit cycle condition, the analytic solution for the build-up steady-state operating point condition and the analytic formulas for the limit magnetizing induction are furtherly obtained. Example analysis is to test out the only set of analytic solution for the build-up steady-state condition. Thus the analytic solution for the build-up steady-state condition produces the formulas of the torture and the power factor which can be applicable to further analysis for the system dynamics and build-up steady-state operating performance, showing practicability and referenced value in engineering.
