Amit Kumar, V. K. Sharma

Abstract: In this paper, a mathematical model of the Self-Excited Induction Generator (SEIG) is developed to analyze the operation of it in wind energy systems. In such type of wind scheme often whole generating system is isolated from the grid and supply electricity to the remote communities. A wind energy system usually a low/medium speed projects driven by controlled/uncontrolled micro wind turbines. The single point operation of these generators is realized; in such a manner that speeds, voltage, currents of generators remain constant under various operating loads conditions. The Electronic Load Controller (ELC) is modeled here for the controlled operation of WES against various load condition. Here the proposed electrical system are 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 this model different characteristics of SEIG with ELC are analyzed which shows its suitability in wind energy systems.
