Electric Machinery

This standard contains requirements for all types of 50 and 60 Hz synchronous generators and generator/motors rated 5 MVA and above to be used for hydraulic turbine or hydraulic pump/turbine applications.

The requirements in this standard apply to all types of 50 Hz and 60 Hz salient-pole synchronous generators and generator/motors rated 5 MVA and above to be used for hydraulic turbine or hydraulic pump/turbine applications.

General recommendations for the operation, loading, and maintenance of synchronoushydro-generators and generator/motors are covered. This guide does not apply to synchronousmachines having cylindrical rotors. In this guide, the term hydro-generator is used to describe asynchronous machine coupled to a hydraulic turbine or pump-turbine. This guide is not intended toapply in any way to the prime mover.

The general parameters for this guide apply to 50 Hz or 60 Hz synchronous generators driven by reciprocating engines, steam turbines, combustion turbines, and hydro turbines. The guide generally applies to the stator and rotor of generators with rated outputs of 1 MVA and above. The guide does not address machine auxiliaries or the excitation system.
