The main drawback of induction generator in wind energy conversion systems applications is its need for leading reactive power to build up the terminal voltage and to generate electric power. Using terminal capacitor across generator terminals can generate this leading reactive power. The capacitance value of the terminal capacitor is not constant but it is varying with many system parameters l...

Due to the advantages of a self-excited induction generator (SEIG), it plays main role in sources renewable energy, such as wind turbines (WT). The regulation terminal voltage and frequency is poor under variable rotor speed load conditions at stand-alone operation mode. depends on excitation capacitance which can be controlled by capacitor bank static compensator. dynamical model machine descr...

Self-excited induction generators (SEIGs) are used in wind turbine system because of high reliability, rigidity, simple structure, and capability to work under severe badly operating conditions. This type generator has a poor terminal voltage frequency regulation during changing the connected loads due absence constant excitation current. Therefore, it is essential stabilize generated besides s...

Self-excited induction generators (SEIG) offer many advantages as variable-speed generators in renewable energy systems. Small hydro and wind generating systems have constraints on the size of individual machines, and several induction generators must be paralleled in order to access fully the potential of the site. SEIGs connected in parallel may lose excitation momentarily owing to large tran...
