Novel Configuration of a Three-phase Induction Generator for Single-phase Load: Simulations and Experimentations

This paper presents the study of an original configuration of an off-grid single-phase generator using a three-phase Squirrel Cage Induction Machine (SCIM). In this proposed structure, two of the generator stator windings are excited by two independent sources and the remaining winding is connected to the load. This configuration requires two voltage inverters for excitation. This allows better control flexibility in the inverter-assisted topology. Simulation model of the generator has been created to study its dynamic and steady-state characteristics. These behaviors of the generator have been verified using comprehensive laboratory tests. The use of this generator configuration is proposed according to the concept of frugal innovation to propose cheap solutions for rural electrification in remote areas in developing countries.
