Question

IEEE Std 1110-2002 - IEEE Guide for Synchronous Generator Modeling Practices and Applications in Power System Stability Analyses

a) Basic Information about the Standard: Name, number and issue date of the standard

b) One to three sentences discussing what the specification covers (For example, “This standard covers the testing method of a synchronous machine to obtain the machine parameters…”).

c) Answer the following question in your own words: Why is the standard important? (Obviously, if it wasn’t important, no standard would be necessary.)

d) Answer the following question in your own words: If this standard did not exist, what would be the impact of not having this standard?

e) In two to four paragraphs, describe the content of the standard. If you can include an example, that would be helpful, but it is not required.

f) Provide a two to four sentence summary of what you covered above. Don’t just repeat yourself. Use this opportunity to help the reader of your document understand what you think they should know about this standard.

Answer 1

a) NAME:IEEE Guide for Synchronous Generator Modeling Practices and Applications in Power System Stability Analyses

NUMBER: IEEE Std 1110^TM-2002 (Revision of IEEE Std 1110-1991)

ISSUE DATE:11 November 2003.

b)

1. Discusses the various categories of stability studies which are commonly performed during power system studies and the corresponding synchronous generator modeling requirements.
2. Reviews some of the basic principles of synchronous generator modeling and discusses the range of models which can be used in the study of synchronous generator dynamic behavior.
3. Emphasizes the point that a model is uniquely determined only when both its structure (e.g., the number of assumed conducting paths in the rotor) and its parameters (as obtained from test data or analytical techniques) are specified.
4. Presents guidelines as to how the various models discussed in Clause 4 can be applied to the various types of stability studies.
5. Discusses the effects of saturation on the performance of synchronous machines and various techniques which have been developed for incorporating these effects in synchronous generator models.
6. Discusses the techniques which have been developed for obtaining parameters for synchronous generator models.
7. The issue of the translation of parameters from the inductances and resistances of d- and q-axis models to transient and estrangement reactances and time constants or to transfer functions form is also discussed.

c) Standrads are un seen forces such as specifications, regulations and protocols that make to work properly.

d) if standandars are not there then it will be

• no unique measurement
• non-singular
• ambigious
• in consistance
• un aditable
