REVIEW OF LITERATURE ON INDUCTION GENERATORS AND CONTROLLERS FOR PICO HYDRO APPLICATIONS

Operation of Induction motors as induction generato rs in grid connected and self excitation mode is well known. In many countries induction gen erators are used for electrical power generation by wind energy. Low cost,robustness and ease of maintenance are attractive features of induction generators. Even though these generators are used at some places for micro hydro power generation,very small scale gene ration known as pico hydro generation offers excellent opportunity for them. S lip ring induction motors are used for micro power generation and squirrel cage induction motors are used for pico power generation. These generators have an inherent probl em of terminal voltage variation with increase in load. Several different types of contro llers are developed and tested. This paper presents a review of literature related to the pres ent status of research work on self excited induction generators (SEIG),their terminal voltage control strategies and their applications. https://www.ijiert.org/paper-details?paper_id=14022
