Determination of Synchronous Generator Model Parameters in the Laboratory and Selected Generating Unit Element Model Parameters in Power Plants

Abstract

This chapter presents the calculation results of model (type XT) parameters of a synchronous generator (PN = 44 kW) operating in the laboratory obtained with the use of the measured waveforms after introducing a PRBS disturbance in the generator voltage regulation channel. Determination of model parameters of synchronous generators operating in power plants is also presented. Sample calculations of mathematical model parameters of synchronous generators were made on the basis of dynamic waveforms recorded at the Pątnow Power Plant (PN = 230 MW—GENROU model) and Halemba Combined Heat and Power Plant (PN = 50 MW—RL models, GENROU model). Determination of parameters of the excitation system models is described in the further part of this chapter. Sample calculations of mathematical model parameters of the excitation systems operating in the Polish PS were carried out based on the dynamic waveforms recorded in the Pątnow Power Plant (electromachine excitation system model) and Skawina Power Plant (static excitation system model). Conclusions drawn from the calculations of the synchronous generator and excitation circuit model parameters as well as some comments on the errors of parameter estimation of the generating unit element models are given at the end of the chapter.
