Synchronous Generators and Excitation Systems Operating in a Power System

In simulation tests of dynamic states of the power system (PS), the database of parameters of mathematical models of generating units is most commonly used. In many cases, the parameter values are burdened with large errors. Consequently, the results obtained are not reliable and do not allow drawing true conclusions. This monograph presents the developed methods and tools supporting the process of measurement determination of reliable values of parameters of mathematical models of synchronous generators and excitation systems. Special measurement tests are the basis for determining the parameters. The tests can be carried out in conditions of normal operation of generating units, in which electrical machines operate in the state of saturation of magnetic cores, and voltage regulators can reach limits. This book is intended for specialists in power engineering as well as students of faculties of electrical engineering interested in issues of PS transient states.

Presents measurement methods and the most essential results of analyses concerning the parameter estimation of mathematical models of synchronous generators and excitation systems operating in a power system Discusses various mathematical models of the synchronous generators and excitation systems working in the power system in detail Explains the measuring methods developed, the devices constructed, the results obtained and the conclusions drawn, which are used for simulation investigations aiming at the assessment of causes and results of system failures associated with the transient states of a power system, assessment of the system angular stability, optimization of the installation site, and parameters of power system stabilizers, while also assessing the effect of connecting new generating units to the power system
