DEVELOPMENT OF VOLTAGE REGULATOR FOR 3- PHASE SELF - EXCITED INDUCTION GENERATOR USING SATURABLE CORE REACTOR

Abstract

The dissertation concerns the design, fabrication and per-formance of voltage regulator for three-phase self excited induc- tion generator using saturable core —reactor. The performance of three phase self excited induction generator is experimentally investigated to study the effect of various parameters such as speed, load, capacitors etc. For the development of voltage regulating system, saturable core reactors with its feedback circuits are designed and fabricated. A voltage. regulating sys- tem for three phase self excited induction generator is realised by using saturable core reactors in parallel with fixed valued capacitor bank. The steady state and transient performance of self excited induction generator with the developed voltage regulating system under different loading conditions is investigated. It is found that the induction generator with its voltage regulating system is capable of starting as well as running a three-phase cage induction motor alongwith other static loads. From the experi- mental investigations, it is concluded that the developed voltage regulator works satisfactorily under steady state and dynamic loading conditions.
