Voltage Regulation of Stand Alone 3-Ø Self-Excited Induction Generator with IGBT-Based Electronic Load Controller (ELC)

This article presents the voltage regulation of a stand-alone 3-ᴓ self-excited induction generator with IGBT-based electronic load controller (ELC). The single-point operation of these generators is realized in such a manner that speeds, voltage, currents of generators remain constant under various operating load conditions. The electronic load controller (ELC) is modeled here for the controlled operation of WES. Here the proposed electrical system is modeled and simulated in MATLAB using Simulink and Sim Power System (SPS) set toolboxes and different aspects of the proposed system are studied. On the basis of this model, different characteristics of SEIG with ELC are analyzed which shows its suitability in wind energy systems.
