Mukhriz,
I didn't noticed that you had also used the book of Kimbark, which I am trying to suggest for you to use. As far as I know, there are some organizations (i.e. EPRI, Siemens, GE) that did multimachine stability calculations through hand. However, access to these information may be difficult. For now, simulation will do for your work.

yes,i do familiar with MM simulation using software.Just looking for a good example.of hand calculation, using classical model ( thats the normal model used in literature)
A good understanding of the theory is crucial even though we know how to simulate but if we do not know the theory and calculation behind it,something is lacking.
Why MM? Thats normally happens in reality, machine connected to infinite bus.is just theoretical.

[QUOTE=BabyBear;333827]Try looking for Power System Stability Volumes I-III by Kimbark. There is a portion in the book that treats multimachine stability calculation. However, the machines here are treated to be classical models, not the detailed models i mentioned before. Here's the general idea: multimachine stability calculation is just done to give an idea on how an interconnected power system works.
Why do you want to look for multimachine stability calculation? As mentioned before, it only considers elementary machine model, not the detailed one. So if you are trying to be familiar with the multimachine stability analysis, a simulation is best to start with.[/QUOTE]
I think no literature really look into this because of tedious calculation.Kinbark and fouad do have the example,almost the same as what I look for.

Why multimachine stability analysis? You need to see the effect of machine inertia and individual generator exciter responses on power system during steady-state and disturbance periods.
example 2.6 and 2.7 ( PM Anderson, AA Fouad) is good.

In the absence of generator actual model including the exciter* what will be the best selection of the models available in the library? Same with the motors which we may not have the actual modelling.
Anybody can suggest which models to select for ' almost' accurate analysis?

that's hard to give almost accurate results. it depends on your objectives* you can always start with classical models.

What about the motor modelling?
We have flux induction motor model* single or double rotor and graphical rotor.
As for load we have exponential* graphical* poly and damping.

There are references that provide idea on how to select generator models from prime mover fuel types. If you really want a generic model* you may use GENROU* and ***S for round rotor generator and typical exciter models in PSS/E* respectively. Use default values.
These models are "Generic Models" in the standard PSS/E library.
[QUOTE=BabyBear;329611]Mukhriz*
PSS/E provides information on how to use exciter/governor models. The model of exciters/governors sometimes depends on the generator manufacturer/supplier and or prime mover fuel types. Two options are available. First* select an exciter/governor model from the PSS/E dynamic model library and fill out the required data. Second* create a dynamic model for exciter and governor (only for model writers). You can check also IEEE Guide for Excitation System models for further information.
For transient stability studies* the benchmark is in favor of PSS/E while some engineers prefer PowerFactory. It's still up to the engineer on which software should be used depending on the standard (American/European) and the method of calculations adopted.[/QUOTE]
could you share pss/e
thanks
