A digital governor for hydrogenerators

IEEE Transactions on Energy Conversion, 1988
The authors describe the development and testing of a microcomputer-based digital governor for hydrogenerators. The digital governor was shown to approximate the control function of existing analog controllers. This task was performed as a first step to future work intended to utilize the versatility of microcomputers in effecting more sophisticated ...

Asynchronous operation of hydrogenerator calculation verification by tests on old hydrogenerator in power plant

Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat. No.04CH37521), 2004
The extended testing of hydrogenerator (rated 35 MVA) was made because the generators working age expired and it was going to be replaced with new one. This was the perfect opportunity to do some specific and not usual testing. The complicated testing plan was designed in order to enable recording as much relevant data as possible (electrical ...

Experimental model of a hydrogenerator with static excitation

2011 IEEE EUROCON - International Conference on Computer as a Tool, 2011
In this paper is presented an experimental model for an hydro aggregate with synchronous generator having static excitation. The model was designed and achieved in the laboratory at reduced scale, of 12 kVA, using a VI — LabVIEW environment. With the help of this model there might be experimentally studied the dynamic conditions of the real hydro ...

Mechanical behavior of hydrogenerator endwindings

IEEE International Electric Machines and Drives Conference. IEMDC'99. Proceedings (Cat. No.99EX272), 2003
This paper presents experimental investigations on hydrogenerator endwinding vibrations and temperatures. In steady-state operation, links between machine load, winding mechanical characteristics, and temperature are discussed. Viscoelastic properties of coil composite sections are proved.

Hydrogenerator insulation maintenance practices

1983 EIC 6th Electrical/Electronical Insulation Conference, 1983
Reliable generation requires a comprehensive preventive maintenance program to locate defects and arrest deterioration on electrical generating equipment. This paper outlines one utility's preventive maintenance and investigative practices on hydro-generator insulation systems and describes experience on some of the major repairs and overhauls.
