Abstract

This paper describes a control structure for a vector controlled doubly-fed induction generator, used for a variable speed energy conversion system, driven by a diesel engine. The paper focuses on an energy system, feeding an isolated load, with two back-to-back PWM converters connected between the stator and the rotor for sub and super synchronous speed operation. A d-q reference frame aligned with the stator flux is used for rotor current control, with correct orientation assured by controlling the q-axis rotor current. Indirect control of the stator voltage is achieved by regulating the stator flux via the d-axis rotor current. Minimum fuel consumption of the diesel, for any given load, is obtained by regulating the speed to follow an optimum operating curve. Given the non-linear characteristic of the diesel engine, a fuzzy logic structure is used to adapt the parameters of the speed controller. Results are presented for step load impacts and for the tracking of the optimum speed.
