A novel, cost-effective stand-alone generator system

A brushless, doubly-fed stand-alone generator system can have advantages over both conventional as well as power converter-based approaches. This paper introduces and discusses the characteristics of a stand-alone generator system based on a brushless, doubly-fed machine (BDFM). Results of steady-state studies are presented for different load and speed conditions. Experimental results using a low power laboratory prototype are presented to illustrate system viability.
