Stand alone power generation by 3φ asynchronous generator: A comprehensive survey

This paper presents a literature survey on the stand alone power generation using three phase asynchronous generator. Induction generators are increasingly being used in non-conventional energy systems such as wind, micro/mini hydro, etc. The advantages of using an induction generator instead of a synchronous generator are well known. Some of them are reduced unit cost and size, ruggedness, brushless (in squirrel cage construction), absence of separate dc source, ease of maintenance, self-protection against severe overloads and short circuits, etc. In isolated systems, squirrel cage induction generators with capacitor excitation, known as Self-Excited Induction Generators (SEIGs), also presented the importance of renewable source of energy (solar energy, wind energy, geothermal energy, tidal energy) in energy crisis. Auther strongly believe that the survey article will be very much useful to the research for finding out the relevant references in regarding with self excited induction generator network and it is also helpful for power generation in remote area.
