Trouble-Shooting Large Hydroturbine Bearings
Special problems associated with very large thrust and guide bearings and lubrication systems are presented, and cover common trouble spots, with examples. Various large hydroturbine bearing...
Hydroelectric Generator Rewinding Pitfalls and Means to Ensure Success
The failure or success of generator rewinding begins well before the actual rewind, and many of the pitfalls can be avoided if owners take some very important steps prior to the rewind...
Problems Associated with Large Hydro Generators
Since the early 1950s, hydro generators have increased in size from the 50 MVA range to much larger units employed today, many of which are in excess of 500 MVA. Such a tenfold increase...
Optimizing Joint Load Control for Hydroelectric Plants
This paper discusses a method to minimize water usage at a multi-turbine hydroelectric generating plant. At plants which do not spill water this optimization is directly converted to extra...
