Guide for Operation and Maintenance of Hydro-Generators
|Publication Date:||28 January 1999|
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.
Limitations due to various designs
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.

A thorough interchange of design requirements should exist between the user and the manufacturer. The user should clearly specify, in addition to the usual nameplate data and machine characteristics, the planned operating modes of the generator in as much detail as possible. Based on industry standards and sound design and operating practice, this information will establish the nameplate rating, temperature limits, and capability curves. The manufacturer is responsible for understanding the requirements and producing a machine to perform as required.View Less
