Abstract

Nearly all of the electric energy used for numerous applications in today's world, regardless of the assembly of the used prime movers, is generated by means of synchronous generators. These generators can be connected together in small-scale or large-scale generation power systems depending on the load demand. Indeed, it is of utmost necessity to pay serious attention to those electric machines, their performance characteristics, various operation conditions and their design parameters. One of the most important parameters of the synchronous generator that can be a good asset for synchronous machines designers is the synchronous reactance. The importance of this reactance lies in the significant role it plays in the quality of the produced electric power and thus the stability of the voltage obtained across the terminals of a synchronous generator. The synchronous reactance of a synchronous generator may have different values based on the mode of the operation or the loading conditions. The primary purpose of this thesis is to determine the direct-axis synchronous reactance values as well as the identification of stator leakage reactance of a real synchronous generator from the so-called Potier triangle method. A set of standard tests based on the IEEE standard 115 is set forth and conducted on the machine under test which is a laboratory synchronous generator of a salient-pole type, or so-called hydroelectric or waterwheel generator. The experimental test data and results are provided and analyzed with full details, and then the relevant machine parameters are calculated at the end of this thesis.
