Indirect Vector Control of Squirrel-Cage Induction Generator

Abstract

Aims: This paper presents the control of the output torque of SCIG using indirect vector control (IVC) technique.
 Study Design: IVC is very popular in industrial applications, which doesn’t rely on the measurement of the airgap flux because the devices that used to measure the air-gap flux is inaccurate in low speed. The IVC technique has been presented to control the torque of the generator and maintain the flux unchanged.
 Methodology: The performance of the proposed system is tested using MATLAB/SIMULINK.
 Results and Conclusion: Simulation results are introduced showing improvement control system performance.

Integration of Wind Systems with SVC and STATCOM during Various Events to Achieve FRT Capability and Voltage Stability: Towards the Reliability of Modern Power Systems

“…To keep the quality of the power supply, frequency and voltage regulation as key factors must be taken into consideration, whereas a balance between the generation of real and reactive power (Q) flow and the demand for load must be maintained so that the reliability of the power grid is not threatened. In the earliest periods of wind energy generation development, the industry was dominated by fixed-speed wind generators (FSWGs) fitted with a squirrel cage induction generator (SCIG) [11][12][13][14]. By now, new and improved wind turbine (WT) technologies have appeared, like the doubly fed induction generator (DFIG) [15][16][17] and the permanent magnet synchronous generator (PMSG) [18][19][20].…”
