Abstract
Nowadays, global warming is the main issue throughout the world because the temperature is surging due to increase in consumption of fossil fuels like coal and petroleum products. Therefore, renewable energy sources are getting attention among researchers to supply electric power for the modern world. Due to reduced cost, less maintenance, rugged and without brush construction, the self-excited induction generator (SEIG) is recommended for distributed generation. One of the most promising renewable energy sources is wind energy which is used as prime mover to self-excited induction generator (SEIG) located in remote areas in isolated mode. This paper presents steady-state reliability analysis of three-phase SEIG considering constant-frequency, constant-speed and variable-speed frequency-generating schemes. Simulation result reveals that SEIG-based electric system yields higher output for low and high wind speeds, it is free from synchronization problem, and frequency is constant for load variation at a particular rotational speed. Therefore, SEIG is useful for residential and commercial load, mini and micro hydro power plant and resistance heating load.
