3. OPERATING PRINCIPLE
3.1. OPERATING DESCRIPTION
HYDRAULIC GENERATORS
OPERATING PRINCIPLE
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.
Dynaset Oy | Menotie 3, FI-33470 Ylöjärvi, Finland | tel: +358 3 3488 200 | info@dynaset.com | www.dynaset.com
23
HYDRAULIC GENERATORS
OPERATING PRINCIPLE
Compound regulator is connected to the auxiliary windings. The regulator
maintains the output voltage constant through the entire load range with accuracy
of ± 5%. Compound regulator sets the excitation current according to electric load
of each phase individually with its separate current windings.
Electronic voltage regulator is connected to the stators windings and achieves an
accuracy of ± 3%. Electronic voltage regulator constantly compares output voltage
to the pre-adjusted reference value and sets the excitation current according to
the load.
The response time of the voltage control is less than 1 second.
3.3. PERFORMANCE OF AUTOMATIC FREQUENCY CONTROL
RPM-cartridge maintains rotation speed of the hydraulic motor so that the
frequency is constant (±5 % ). The output power remains stable (±5 %) even when
the hydraulic flow (Q) exceeds the nominal flow (Qnom) up to 20-30% l/min,
depending on HG hydraulic generator size.
3.4. PRESSURE POWER RATIO
Picture 12: Automatic frequency control
Following chart in picture 13 describes the power to pressure ratio. The chart
shows output powers relation to the pressure, when the hydraulic flow Q is kept
constant. The best power to pressure ratio is achieved when the pressure is at
nominal level, little under the maximum value. READ CHAPTER „10. TECHNICAL
