Analysis and modeling of the steady state behavior of the static Kramer induction generator

A steady state analysis of the static Kramer variable speed double output i nduction generator is conducted using a hybrid dq model wherein stator vari ables only are transformed onto a reference frame fixed to the rotor. Rotor variables are retained in their natural abe form, allowing diode bridge ov erlap together with snitching effects in the rectifier and inverter to be c atered for. For constant speed operation the system equations are reduced t o a set of linear differential equations with constant coefficients which a rt: solved analytically to predict generator performance. Simulated perform ance is verified experimentally showing very good agreement with measuremen t.
