Parameter of Steam Tubine Generator?

09/24/2010 3:56 AM

Hi Friends. I have many parameter of steam turbine generator to be used for load flow, short circuit and transient stability study using ETAP software. But I can not understand clearly about those. Can you explain to me what is the purpose of those parameter and which parameter is used for load flow, short circuit or stability:

- Impedance: Xd", Xd''/Ra, Ra (%), Ra (Ohm), X2, X2/R2, R2 (%), R2 (Ohm), Xo, X0/R0, R0 (%), R0 (Ohm), X/R, Xd" Tolerance, inertia H,

- Xd, Xdu, Xd', XL, Xq, Xqu, Xq', Xq", Tdo', Tdo", Tqo', Tqo", Sbreak, S100, S120.

Generally Load flow stidies don't consider any of the reactance values.

Short circuit calculation:Xd", Xd''/Ra, Ra (%), Ra (Ohm), X2, X2/R2, R2 (%), R2 (Ohm), Xo, X0/R0, R0 (%), R0 (Ohm), X/R, Xd" ,Tdo', Tdo", Tqo', Tqo

Stability Studies:Xd", Xd''/Ra, Ra (%), Ra (Ohm), X2, X2/R2, R2 (%), R2 (Ohm), Xo, X0/R0, R0 (%), R0 (Ohm), X/R, Xd" Tolerance, inertia H,

- Xd, Xdu, Xd', XL, Xq, Xqu, Xq', Xq", Tdo', Tdo", Tqo', Tqo", Sbreak, S100, S120.

I think you should forget ETAP software for now and start looking at textbooks for the basics.

I can understand someone asking what is variable "XYZ" is in relation to a formula, but not a whole string of variables.

Would you like it read as a bedtime story?

You should do your own research!

Many of the people here paid very good money and worked very hard to obtain our knowledge and understanding of many engineering disciplines. Many here, myself specifically, will gladly help a student of any age that shows that they are working very hard themselves. But I am insulted and perplexed by anyone trying to take a shortcut in education by using my knowledge to further themselves.

Working with steam powered generators is not child's play. This is very hazardous work. If you wish to learn how to work there, sign up to a school. There is a lot of preliminary knowledge you must master first to be able to read a book on steam turbine generators and gain useful knowledge. For an example, you must understand the concept of enthalpy without looking it up in Wikipedia.
