Abstract :
This paper presents the results of the overheating investigation in three synchronous generators of 71.9 MVA of a hydroelectric power station, that exceed the norm under which were designed, the heating restricts the generation of reactive power. A design verification methodology of salient poles synchronous generators based on the entire verification of the main dimensions of the magnetic circuit was created, simulation in no load and under load by means of finite elements method (EMF), selection of the number of slot and design of the winding of the stator based on the study of harmonics of electromotive (emf) and magneto-motive (m.m.f) forces elaborating the complex matrix of the winding. The comparison of standard theory data and tests in site appears
