Introduction This introduction is not part of IEEE Std C50.12-2005, IEEE Standard for Salient-Pole 50 Hz and 60 Hz Synchronous Generators and Generator/Motors for Hydraulic Turbine Applications Rated 5 MVA and Above . T
9、his introduction provides some background on the rationale used to develop this standard. This information is meant to aid in the understanding and usage of this standard. From the early 1990s until the date of issue of this standard, two different working groups of the Electrical Machinery Committe
10、e (EMC) of the IEEE Power Engineering Society have carefully pursued the modernization of the ANSI C50 standards for large steam turbine and combustion turbine generators. Throughout the mid-1990s, the first working group (IEEE PES EMC Task Force on Standards Harmonization) compared American Nationa
11、l Standards Institute (ANSI) standards for several different types of electrical machines with corresponding International Electrotechnical Commission (IEC) standards. In the late 1990s, members of the EMC Task Force published several summaries of their work B2, B11, B15, B16.a In association with t
12、he general initiative by the Electric Machinery Committee to compare different standards for electric machines, the Synchronous Machinery Subcommittee (SMSC) of the EMC commissioned a second working group in 1998 to focus on clarifying and modernizing the ANSI C50 series of standards for synchronous
13、 generators. The SMSC Working Group (WG) No. 4 (Revision of ANSI C50.1X series) included the following ANSI C50.1X standards in their scope: a) b) c) d) e) ANSI C50.10-1990, Rotating Electrical MachinerySynchronous Machines. b ANSI C50.12-1982 (Reaff 1989), Requirements for Salient-Pole Synchronous
14、Generators and Generator/Motors for Hydraulic Turbine Applications. ANSI C50.13-1989, Requirements for Cylindrical-Rotor Synchronous Generators. ANSI C50.14-1977, Requirements for Combustion Gas Turbine Driven Cylindrical Rotor Synchronous Generators. ANSI C50.15-1989, Hydrogen-Cooled, Combustion-Ga
15、s-Turbine-Driven, Cylindrical-Rotor Synchronous GeneratorsRequirements. The SMSC WG No. 4 has periodically reported their progress B3, B4, B5, B12. As has been communicated in these papers, where it has been possible for this group to agree to the appropriateness of requirements recorded in IEC 6003
16、4 standards B6, B7, those requirements have been incorporated into the revised ANSI C50.1X series of standards. As the most workable approach to clarify and modernize the IEEE/ANSI standards for cylindrical-rotor synchronous generators the SMSC WG No. 4 chose to consolidate the previously separate A
17、NSI C50.10, ANSI C50.13, ANSI C50.14, and ANSI C50.15 standards into one consolidated IEEE Std C50.13 standard. This modernized IEEE Std C50.13 has been written to consolidate the previously separate ANSI C50.13, ANSI C50.14, and ANSI C50.15 standards in their entire scope and to incorporate applica
18、ble parts of ANSI C50.10. Similarly, WG No. 4 chose to modify ANSI C50.12 to become a consolidated standard for large salient-pole generators and generator/motors for hydraulic turbine applications. All applicable parts of ANSI C50.10 have been incorporated into the modernized IEEE Std C50.12. Also,
19、 wherever possible, the modernized IEEE Std C50.12 and IEEE Std C50.13 have been harmonized with each other. a The numbers in brackets correspond to those of the bibliography in Annex A. b ANSI publications are available from the Sales Department, American National Standards Institute, 25 West 43rd
20、Street, 4th Floor, New York, NY 10036, USA (http:/www.ansi.org/). iv Copyright 2006 IEEE. All rights reserved. The logic to consolidate ANSI C50.13, ANSI C50.14, and ANSI C50.15 into one standard was primarily that ANSI C50.14 and ANSI C50.15 contained a significant amount of content that had been d
21、uplicated from ANSI C50.13 solely to cover different applications of the same basic configuration of generators covered by ANSI C50.13. Additionally, because some newer applications to which no C50 standards directly pertained had occurred since the creation of the separate ANSI C50.14 and ANSI C50.
22、15, the working group had to choose between creating additional highly duplicated standards or finding a way to consolidate them. The decision to drop the general standard, ANSI C50.10, and to incorporate appropriate parts of its content into IEEE Std C50.12 and IEEE Std C50.13 was made after an ini
23、tial attempt to retain and update ANSI C50.10. During that effort, it was recognized that the content directly applicable to IEEE Std C50.12 and IEEE Std C50.13, respectively, was not that great. It was also recognized that most ultimate users of the generator standards would significantly benefit f
24、rom having a single standard for each of these two major types of machines. This approach would provide a better focus and alignment of the standards to purchasers and manufacturers knowledgeable in each product affected by the standard. That better focus and alignment would minimize the risk of con
25、flict or ambiguity between the general and type- specific standards, reduce the risk of missed requirements or ineffectively communicated requirements, and also ease future maintenance of the standards.
