Implementation of a conventional DFIG stator flux oriented control scheme using industrial converters

This paper presents a vector control implementation procedure for a small-scale doubly-fed induction generator test facility utilising standard industrial converters. Conventional industrial converters can pose significant limitations in practical execution of stator flux oriented vector control schemes for doubly-fed induction generator drives due to inherent limitations in available pre-programmed inverter operation modes. This work presents a practical method for implementation of a conventional doubly-fed induction generator stator flux oriented vector control scheme on industrial converters via a dSPACE real-time platform and a commercial speed/position communication module. The developed control algorithm implementation procedure is explained and validated in laboratory tests on a 30 kW test system.
