Texto completoThis thesis deals with thermal and mechanical stress that undergoes hydrogenerators stator insulation. More precisely, this study concems the stator endwinding zone. Thus, ail over the first chapter, stator winding structure and insulation stresses are described. This first part is concluded by a short présentation of on-line monitoring Systems and some pièces of information about their présent limits. The second chapter concems mechanical behavior of hydrogenerator endwindings. Materials non-homogeneity is taken account by three-dimensional and straight beam models moreover, endwinding geometry is described in détail. In the following step, thèse meihods are applied to analyse a single endwinding and the whole winding eigenforms. The third chapter contains a vibrations and température expérimental study of three generators-motors used in power generating units. Front the study of many steady-state recordings, insulation viscoelastic properties are proved. In the same way, mechanical transient analysis (starts and stops) shows that : * endwinding forces hâve mainly electromagnetic origins * the electrical braking during the stop séquences may lead to high vibration levels caused by machine naturel frequencies The last chapter purpose is to présent an expérimental testing bench able to repnoduce, on a short part of a generator bar, thermal, mechanical and high voltage stresses measured on real machines. Technological solutions chosen are justified and illustrated by many pictures. To conclude, an analytical method for predicting insulation mechanical stress level is proposed and compared with expérimental data
