The performance and unique characteristics of induction generators as they relate to the protection of the units are discussed. Machines in the range of several kW up to 1500 kW are considered. Contrasts are provided to demonstrate the differences in protection suggested for traditional synchronous generators and induction units. The need for overvoltage protection due to self-excitation of induction generators under load rejection is addressed. Recommendations are provided for the minimum amount of protection on these units in several electrical system configurations as they might apply to single or multiple-unit installations
