INVESTIGATION OF STATOR TRANSIENT INFLUENCE ON THE SIMPLEST ELECTRICAL TRANSMISSION DYNAMIC STABILITY

Investigation results of the synchronous machine stator transients influence on the dynamic stability of the regulated synchronous machine are given in the paper. Stability indexes which are got on the basis of synchronous machine "complete" or "accurate" model using (model with inclusion of , P terms and of (1+s) factors by flux linkages in stator equations), and also with exclusion of these terms are considered in the simplest electrical transmission scheme. It is showed that influence of noted factor in the case of noticable stator circuit resistance can be essential. Main methods of investigation were calculating of stability domains and elgenvalues analysis.
