scope:

This guide was prepared to set forth operating experience and maintenance practices that have been used successfully over a period of years by several major operators of hydro-electrical equipment. Accompanying the operating and maintenance background has been the input of manufacturers of large electrical equipment, resulting in a combination of experience factors and design philosophy that will provide users with information to guide them in understanding the limits of the equipment and methods that may be employed to reduce downtime to a minimum.

The development of this guide was begun in early 1969, when it was felt that a document similar to IEEE Std 67-1972, IEEE Guide for Operation and Maintenance of Turbine Generators (ANSI C50.30-1972), should be available to operators of hydro-electric equipment. Such a document was considered to be of particular value to organizations normally involved only with turbine-generators, but who had entered the hydro-electric field to meet the increasing energy of peaking needs. To this end, the guide contains some sections devoted to pumped-storage applications. A substantial revision toward the current document was begun in 1987. It is considered desirable that this guide be updated and that the pumped-storage sections be expanded as future needs dictate. Comments are invited on this guide as well as suggestions for additional material that should be included.

This guide covers general recommendations for the operation, loading, and maintenance of synchronous hydro-generators and generator/motors. It does not apply to synchronous machines having cylindrical rotors. In this guide, the term hydro-generator is used to describe a synchronous machine coupled to a hydraulic turbine or pump-turbine. This guide is not intended to apply in any way to the prime mover.

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

Equipment manufacturers have taken different approaches to the solution of design requirements; therefore, it is not practical to relate specifically in this guide to all the variations of machine design. However, many of the operational and maintenance procedures and problems are common to all the designs and, therefore, recommendations are given concerning solutions to these procedures and problems. The most that this document can accomplish is to provide guidelines, which, on one hand, disclose accepted and tried values or methods, and on the other hand, give warnings where hazards might be encountered.

This guide does not cover in detail associated rotating or stationary excitation systems.
