Abstract

This paper deals with an electronic load controller (ELC) for a standalone induction generator (IG) used in small hydro power generation. The proposed ELC is used to control the voltage and frequency of IG. This ELC is realized using a non-isolated T-connected transformer and three-leg insulated gate bipolar transistors (IGBTs) based current controlled voltage source converter (VSC), a capacitor, a chopper switch and an auxiliary load on its dc bus. The proposed ELC is implemented on a prototype of 3.7 kW 50 Hz IG. Test results of IG-ELC system are presented to demonstrate its performance for feeding three-phase four-wire loads with the neutral current compensation.
