Identifiering av synkronmaskinsmodell genom SSFR-test
At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received. Based on this set of basic parameters a mathematical model hasbeen matched to fit the measurement data so that the last unknown parameters couldbe obtained. The result of the analysis and fit gave a set of parameters. The set ofparameters resulted in a more or less good fit to the measurement data. It has beenshown that even though the parameters are based on the generator itself it does notnecessarily give the best fit. As a verification of the parameters, which has beenreceived from the test, further work is needed by implementing the parameters into adynamic model and then compare that model with measured responses fromelectrical or mechanical interference of the generator.
