Typical Applications of Induction Generators and Control System Considerations

Induction generators are seeing increasing use for energy recovery applications because of their inherent simplicity and ease of connection to an electrical power system. Often questions concerning induction generator control considerations are presented. These include power system short-circuit contribution, automatic reclosure after a power outage, power factor correction, system startup, and self- excitation. Induction generator applications and control considerations often encountered are addressed, and some answers and ideas are provided for the engineer planning an induction generator energy recovery system.
