Overview of Wind Turbine Driven Self-Excited Induction Generator

this paper presents an overview of the analysis, modeling as well as controlling of self Excited Induction Generator (SEIG) which is connected by Wind Turbine. The AC capacitors are used to build up the process of an isolated induction generator starts from charge in the capacitors or from a remnant magnetic field in the core. Same process is done at the time of isolated induction generator is excited by inverter/rectifier system. . A closed loop voltage control scheme using a PWM Voltage Source Converter (VSC), dc link capacitor and a P-I voltage controller is proposed. This scheme generates constant voltage and variable frequency using the converter which also acts as a reactive power compensator. In the growing applications and environmental conditions, various types of technologies are introduced to delivering the power to the grid. The main objective of the project is to track and extract maximum power to the grid connected wind energy conversion system. This paper presents only a proposed approach of self-excited induction generator in wind energy conversion system.
