Introduction

This chapter contains a general description of the developed methods and tools supporting the measurement process of determining reliable values of mathematical model parameters of generating unit elements, in particular synchronous generators and excitation systems. Special measuring tests are the basis for determining the parameters. They can be carried out under normal operating conditions of generating units, in which the magnetic cores of electric machines (synchronous generators and electromachine excitation systems) are saturated and the signals in voltage regulators may reach the limits. In this chapter, there is also a short description of selected methods, known from the literature, for determining (estimating) the parameters of mathematical models of synchronous generators. In the further part of this chapter, the content of this monograph with division into chapters is presented.
