1、 IEEE Std 122-1991 (R2003) IEEE Recommended Practice for Functional and Performance Characteristics of Control Systems for Steam Turbine-Generator Units Sponsor Energy Development and Power Generation Committee of the IEEE Power Engineering Society Reaffirmed 11 September 2003 Approved December 5, 1
2、991 IEEE Standards Board Abstract: Minimum functional and performance characteristics related to speed/load-control systems for steam turbine-generator units that may be interconnected on a power system are recommended. The recommendations apply to the following types of steam turbines, rated at 500
3、 kW and larger, intended to drive electric generators at constant speed without initial steam-pressure control, exhaust steam pressure control, or either: (1) condensing or noncondensing turbines without initial steam-pressure control, exhaust steam-pressure control, or either, including turbines us
4、ed with reheat, regenerative feedwater heaters, or both; (2) condensing or noncondensing turbines with initial and/or exhaust steam-pressure control, including turbines used with reheat, regenerative feedwater heaters, or both; (3) automatic extraction and/ or induction and mixed-pressure turbines.
5、Emergency governors, other overspeed control devices, and, in general, devices that are not responsive to speed are not covered.

IEEE Standards documents are developed within the Technical Committees of the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Board. Members of the commi

The standards developed within IEEE represent a consensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE that have expressed an interest in par

The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthe

Every IEEE Standard is subjected to review at least every ve years for revision or reafrmatio
11、n. When a document is more than ve years old and has not been reafrmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard. Co
12、mments for revision of IEEE Standards are welcome from any interested party, regardless of membership afliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Interpretations: Occasionally questions m

When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned inter
14、ests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason IEEE and the members of its technical committees are not able to provide an instant response to interpretation requests except in those cases where the matter has prev
15、iously received formal consideration. Comments on standards and requests for interpretations should be addressed to: Secretary, IEEE Standards Board 445 Hoes Lane P.O.

Such adoption does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the standards documents. -,-,- iii Foreword (This foreword is not a part
17、 of IEEE Std 122-1991, IEEE Recommended Practice for Functional and Performance Characteristics of Control Systems for Steam Turbine-Generator Units.) The formation of a joint AIEE/ASME committee to prepare a recommended practice covering the speed-governing of prime movers intended to drive electri
18、c generators that may, if desired, be included in prime-mover purchase specications was approved by the AIEE Board of Directors on January 30, 1941, and by the ASME Council on June 15, 1941. The members of this joint committee were appointed jointly by the chair of the AIEE Power Generation Committe
19、e and by the ASME Standing Committee on Performance Test Codes under sponsorship of the ASME Division. The work of the joint committee resulted in the issuance of AIEE No. 600, Recommended Specication for Speed- Governing of Steam Turbines Intended to Drive Electric Generators Rated 500 kW and Large
20、r, in May, 1949. The joint committee was reorganized in 1955, at which time it updated AIEE No. 600. The joint committee was again reorganized in January 1980, and was instructed to prepare a revision of the recommended specication under the designation of IEEE Std 122 . This revision was expanded t
21、o cover speed and load controls, and the term governor was replaced by the term control systems. The joint committee was reformed in 1987 to update the recommended practice. This revision, like the original, is limited in its scope to steam turbine generators rated at 500 KW and larger, designed to
22、operate on a utility type system. The term control systems now includes torsional effects, transient response, and inuences outside the control system (see Appendix) that should be considered by the purchaser. Users of this text should pay particular attention to the parts of Section 4. that indicat
23、e the need to specify or agree upon limits with the manufacturer. Such specication or agreements should be made before the manufacturer bids on the proposal. This recommended practice does not cover emergency governors, other overspeed control devices, or, in general, devices that are not responsive
24、 to speed. Exceptions to the latter were made for turbines designed to operate with controlling steam pressures, as in the case of turbines with initial or exhaust steam pressure control, automatic- extraction and mixed-pressure turbines, or a combination of these, since the performance of the speed
