Abstract
The generator´s prime mover is susceptible to abnormal frequency operation, and turbine blade fatigue is the main concern. As blade fatigue is cumulative and non-reversible, the turbine abnormal frequency protection should govern the duration of abnormal frequency operation and thus limiting the possibility of turbine damage. This turbine protection is acting as backup protection for the generator. In this paper, the need of turbine blade protection, the method of protection according to IEC standard 60034-1 and IEEE Standard C37.106 are discussed.
