Introduction This introduction is not part of IEEE Std 1665-2009, IEEE Guide for the Rewind of Synchronous Generators, 50 Hz and 60 Hz, Rated 1 MVA a
5、nd Above. At the turn of the 21st century, many of the generators used by electric utilities and industrial plants had reached their design life. Because of todays economics, many of these generators may be called upon to supply reliable service for an additional 20 to 30 years, or more. Any generat
6、or Owner intending to significantly extend the life of the generating plant by rewinding and refurbishing the generator should address three key areas: economics, developing a technical specification, and performance upgrades through better materials/design. A comprehensive economic study should be
7、carried out (for the plant as well as the generator) before the investment of significant resources. This should include plant load forecasts, reserve margins, new capacity plans, cost benefit analyses, operating costs, capital costs, and continued reliability/availability. Once a financial decision
8、 has been made to rewind, it is essential that a technical specification be developed. The technical specification should establish a clear understanding between the Owner and the Vendor, with regard to what the final product will be. Doing so creates an understanding of the level of performance and
9、 reliability expected by the Owner/user and what is required in the manufacturing process to achieve it. In addition, to ensure a quality product is achieved, specific tests, measurements and inspections that are to be required in the manufacturing process need to be clearly spelled out. The technic
10、al specification is a means for these requirements and expectations to be stated. New materials, major component replacement, and other design changes may also affect the life extension decision. For example, the development of better insulation systems has been ongoing for many years in the industr
11、y. The ability to uprate the nameplate output with these new materials may make rewind and refurbishment cost effective. Throughout this guide the term “generator” has been used, instead of “rotating machinery,” in order to simplify the text. Many of the items contained herein are also appropriate f
12、or large synchronous motors. However, this guide does not address machine auxiliaries or the excitation system; nor does it address the generators found in modern wind turbines. The reader is directed to the latest version of the IEEE 421 series of standards for excitation systems. Notice to users L

Overview 1.1 Scope 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 rat
47、ed outputs of 1 MVA and above. The guide does not address machine auxiliaries or the excitation system. 1.2 Purpose This guide will provide the generator Owner with insight into the considerations that are necessary when rewinding or refurbishing a generator. Particular emphasis is placed on the com
48、plete rewind of each of the components of the stator and rotor. 1 Copyright 2010 IEEE. All rights reserved.

49、 hazardous materials such as asbestos, lead carbonate, or lead paint. As an example, many Vendors used asbestos in the stator or rotor insulation system. Some hydrogen cooled units may contain lead carbonate. The presence of lead carbonate is due to a reaction of the water, carbon dioxide, and lead in the solder used to manufacture the coolers. In such cases, abatement work, cleaning, and disposal of hazardous materials shall be performed according to appropriate government regulations.
