scope:

This guide covers general recommendations for the operation, loading, and maintenance of turbine-driven synchronous generators of the types specified in Section 4 below, having cylindrical rotors. It does not apply to generators having salient-pole rotors.

This guide is not intended to supplant specific or general instructions contained in the manufacturer's instruction book or in any contractual agreement between a manufacturer and a purchaser of a given machine.

Because of the rapid development in generator design and because of the ingenuity of individual generator designers, many variations are incorporated in existing machines. It is therefore not possible in this guide to assign specific values or fixed methods. The most that this guide can accomplish is to offer accepted and tried values or methods and give warning where hazards might be encountered. The user should keep in mind that this guide is written in terms of the turbine generator, and that certain considerations herein have been included because of their importance in directing attention to other related matters. This guide is not intended to apply in any manner to the prime mover.

NOTE: It is often practice in industry to refer to various types of power in terms of the units in which these types of power are normally measured. To avoid the possibility of confusion, units of measure are shown in parentheses when the terms reactive power (kvar), apparent power (LVA). and active power (kW)are used.
