Korol S. Mechanical coordinates and reactive power vector control of electromechanical system with doubly fed induction machine

The object of the investigation: electromechanical energy conversion in vector-controlled doubly fed induction machine. The purpose of the investigation: development, theoretical and practical investigation doubly fed induction machine control algorithms that provide torque (angular speed) control with free input reactive power regulation. Methods of the investigation: second Lyapunov method, feedback control, feedback linearization, mathematical and physical modeling. Theoretical and practical results and innovations: Doubly fed induction machine and voltage converter nonlinear vector control algorithm has been designed and investigated. Proposed solution provides asymptotic torque (angular speed) and all system reactive power regulation. A subject and degree of the implementation: results are implemented in NTUU “KPI” and used during wind-generator control system development on SSIE “Electronmash”. The efficiency of the implementation: performances of mechanical coordinate regulation and additional reactive power control of all system energetic efficiency improvement. The sphere of application – electromechanical systems.
