Remote Area Power Systems
Generator Interactive Inverters provide mains quality power efficiently
and automatically. The system uses batteries to store energy for periods
when power demand is low, and automatically starts a diesel generator
set when demand is high or when the batteries require recharging.
This mode of operation ensures that the diesel fuel is efficently converted
to electricity by only running the generator at medium to heavy loads and
only for a small proportion of the day. Power is drawn from the batteries
and converted to a mains quality sine wave by a microprocessor controlled
inverter. While the generator is operating, it supplies power to the load
and the inverter charges the batteries. However if heavy loads occur, both
the inverter and the generator can supply the load, giving a peak capacity
equal to the sum of the inverter and the generator ratings. This allows
smaller generators to be used compared to inverter charger systems.
An alphanumeric LCD display allows inverter variables to be displayed and
allows suitably qualified technicians to adjust operating parameters to
optimise system performance.This is a worked example, showing how to set
up the parameters of a RAPS inverter for a solar-diesel remote power system.
It was prepared by the Renewable Energy Centre at the Brisbane North Institute
of TAFE, as part of their Hybrid Energy Systems course.
3 - 5 kW RAPS Specifications
 Common to all units:
- Automatic Bypass: Supply is maintained by the generator if the inverter
is off line.
- Data Logging Remote Access: RS232 port, standard data logging and
remote access via modem, satellite, GSM and CDMA technology.
- Cooling: Convection and thermostatically controlled fans.
- Enclosures: Electronics IP50, transformer and heatsink IP23. Weatherproof
enclosures or rack mounting are available on request.
- Protection: Over current trip, over voltage, over temperature, reverse
polarity, fast electronic trip, transient over voltage protection.*
AC output voltages of 110, 120, 220 and 230 are available on application.
* Other DC voltages between 24 VDC and 120 VDC are available on application.
