Parks Matrices

Parks Matrices

Parks Matrices

(OP)
Can anybody introduce myself to the joys of Parks Transformation, given that i have induction machine parmeters in both physical and per unit sense. This is first time i have encountered it ,as a new package has been brought in to the employers.
How does the physical parameters relate to the matrices given in various texts, absoulutely bamboozled?, as no texts gives examples on how it is carried out. What im looking to do is get the 0-d-q system resistances and reactances of both the stator and the rotor coils, can anybody give me a push in the right direction

Any help from the experts out there would be very appreciated

RE: Parks Matrices

Suggestion: Reference:
1. Bimal K. Bose "Modern Power Electronics and AC Drives," Prentice Hall PTR, 2002,
page 56 Section 2.2.12 Dynamic d-q Model
Dr. Bose clearly presents an explanation of the d-q model, Park's transformation context and applications.

EXCELLENT REFERECE !!

For that you get a STAR

RE: Parks Matrices

hello,

 0-d-q (Zero Sequence-Direct-Quadrature Axis)Transformation
was briefly discussed, try on this publication:

Electric Machinery, 6/e. AE Fitzgerald Charles Kingsley, Jr. Stephen D. Umans, MIT. Mcgraw-hill

RE: Parks Matrices

The basic idea is very simple. For constant speed, original equations are linear with sine / cosine type variable coefficients. Direct Park transformation transforms the original system into linear time-invariant (constant parameter) equations that can be relatively easily solved. The physical meaning is that 3 stator variables are transformed into 2 (DC style) variables in the synchronously rotating frame.
