Description of power generation system
Drive types, generator
1.3 Drive types, generator
The generator can be powered in various ways.
Installation and required components depend on the drive type
ð
chapter “Installation of generator”, page 26.
1.3.1 Connection via drive shaft
The shaft on the generator is joined to the drive shaft of the drive unit via
a cardan shaft. The generator runs at the same speed as the drive unit. The
drive unit must have a suitable and constantly regulated speed in order to
avoid operating the generator at an under or overspeed which can impair the
function of the generator or may even damage it.
1.3.2 Drive via hydraulic motor
The generator is driven by a hydraulic motor. The hydraulic motor is fed from
a hydraulic system. Do not operate the generator at an overspeed. Operation
at an overspeed can have negative consequences for the functioning of the
generator or may damage it.
1.3.3 Drive via belt pulley
The generator is joined to the drive unit via a belt pulley and a belt. The belt
drive is an especially simple and cost-effective means of transmission. It also
offers the advantage that, by selecting the transmission ratio, it is possible to
optimally adjust the speeds of the drive unit and generator to each other.
