Abstract

The distribution systems and microgrids in remote and rural areas are often of single-phase in nature due to economic viability. However, three-phase induction generators (IG) is a popular machine even in such applications due to the large utility and its competitive price features. This paper proposes a control approach for injecting power to a single-phase grid from an active phase converter (APC) assisted three-phase IG. The presented approach ensures balanced operation of the IG even with variable generation. A method is proposed that reduces the loading on the APC and improves operating power factor at the single-phase grid. Closed form expression of the grid current for a given operating point of the IG is derived. Simulation and experimental results are provided to validate the theoretical framework and APC control approach. The experimental results with a 3 kW IG substantiate the proposed APC control approach injecting 2.6 kW real power into the single-phase grid at near unity power factor.
