“…But no solution is offered for the sensitivity of the system to rotor resistance changes. Authors in [5] propose a stator flux oriented (SFO) vector control. The main advantage of this control method is that it's not sensitive to the changes of the generator leakage inductance.…”

In this paper, a new control strategy is proposed for a three-phase squirrel-cage self-excited induction generator (SEIG) connected to a variable speed wind turbine in autonomous mode. In order to improve the dynamic performance of the mentioned vector control system, a model reference adaptive controller is used for online rotor time constant estimation. Thus, the main drawbacks of this method, which include the effects of the changes in machine parameters on rotor flux estimation, slip speed, the creation of instability problems and the system leaving vector control mode, are resolved. In this control strategy, a PI controller is used to control the dc voltage and three similar hysteresis current controllers (HCC) are used to control the switching of IGBTs. The results of the dynamic simulation indicate the desirable performance of the proposed system.

“…However, this method provides slow transient response and the use of A sinusoidal PWM technique for switching the devices, increasing the switching losses. Vukadinovic and Basic (2011) and Seyoum et al (2003) have presented stator flux oriented vector control for a wind turbine driven isolated induction generator, but this method needs decoupling compensation and vector transformations. The indirect vector control of standalone self-excited induction generator has been reported by El-Sousy et al (2004) and Soundarrajan et al (2012).…”

This paper describes the direct torque and flux control (DTC) of a self-excited induction generator (SEIG) for wind energy conversion systems (WECS). The DTC-based WECS is more suitable for low power applications, owing to several advantages such as good torque control in steady-state and transient operating conditions, not requiring an accurate generator model, the absence of coordinate transforms and current controllers. The SEIG is excited by a voltage source converter (VSC) with a capacitor and start-up battery on the direct current (DC) side. The required reactive power for the SEIG is provided by the capacitor. The terminal voltage of the SEIG varies with wind speed and load conditions. The proposed DTC strategy is used to control the terminal voltage of the SEIG and DC voltage at a constant value when the load and wind speed are varied. The gate signals for the VSC are derived from an inverter switching table. The torque and stator flux of the induction generator are controlled through the voltage space vector selection. The proposed system gives good dynamic and steady-state performance. The effectiveness of the proposed control strategy is verified through simulations. Experimental results are presented to validate the simulation results.
