Sažetak
The paper presents the results of studying the specific problems that occurred during the exploitation of two 42 MVA bulb generators. The work focuses particularly on two groups of problems which were more pronounced on only one of the two hydropower units, and these are increased vibrations of the hydropower unit and electromechanical oscillations in the stationary and transition states, which significantly depend on the operating point of the drive. This paper shows a part of extensive generator measurements. A lot of probes were mounted on the generator measuring all electrical and mechanical physical quantities, as well as air gap width, induction in air-gap and others.
