Introduction This introduction is not part of IEEE Std 67-2005, IEEE Guide for Operation and Maintenance of T

8、urbine Generators. This introduction provides some background on the rationale for updating this guide. The scope of the guide remains the same as the existing guide. It is updated to include the latest industry information that is relevant to the existing standard IEEE Std 67-1990. Original Scope:

9、This guide covers general recommendations for the operation, loading, and maintenance of turbine-driven synchronous generators of the types specified in the guide, that is, having cylindrical rotors. It does not apply to generators having salient pole rotors. This guide is not intended to supplant s

10、pecific or general instructions contained in the manufacturers 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 variati

11、ons are incorporated in existing machines. Therefore, it is 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 and methods and give warning where hazards might be encountered. The user should keep in mi

12、nd that this guide is written to cover the turbine generator. This guide is not intended to apply in any manner to the prime mover. This guide is for the use of the users (power utilities) and manufacturers of turbine generators. The reason for the revision is that it has been ten years since it was

13、 previously revised and it needs updating due to the changes in the operating regimes of utilities today. The guide now includes such things as two-shifting operation information and considers the advances in machine designs. Notice to users Errata Errata, if any, for this and all other standards ca
