Sažetak
A short overview of a calculation of overvoltages in the generator main electrical circuit of a hydro power station is presented. A case of a generator connected to the step-up transformer through encapsulated lines has been studied. The most critical cases have been considered: lightning overvoltages transferred from the high- voltage circuit through the step-up transformer, overvoltages at a single phase earth fault in the generator circuit and temporary overvoltages due to the single phase earth fault followed by the load rejection. The calculations have been carried out by computer programs EMTP-ATP and MicroTran as well as by an analytical procedure. The results of the calculation are commented and compared.
