HYDRAULIC GENERATORS
OPERATING PRINCIPLE
3. OPERATING PRINCIPLE
3.1. OPERATING DESCRIPTION
Picture 11: HG hydraulic generators operating principle
1. When the hydraulic flow is directed through RPM-valve block to the hydraulic
motor. The RPM-valve keeps the flow constant with a RMP-cartridge and
controls the speed of the hydraulic motor.
2. Hydraulic motor actuates the alternator’s rotor through a direct connection
to the rotor. When the rotor spins it produces a changing magnetic flux that
generates electricity.
3. The electricity is directed through the distribution box and on to the selected
output, socket or cable.
3.2. VOLTAGE CONTROL
Voltage regulator adjusts rotors excitation power, maintaining constant output
voltage at fluctuating electric load.
SINGLE PHASE GENERATORS
Voltage control of single phase generator is affected with a capacitor circuit,
connected to an auxiliary windings. Voltage control keeps the voltage constant
through the whole load range with accuracy of ± 6%. The response time of the
voltage control is less than 1 second.
THREE PHASE GENERATORS
3-phase generators are equipped either with compound or electronic voltage
regulator.
