Murdoch University’s Renewable Energy Power Systems (REPS) Facility is designed to give students a practical understanding of how a stand-alone power system operates. The facility allows students and faculty to monitor, adjust and observe a range of system components in the energy generation process.

The facility is designed to manage the power generation of two wind turbines with the option of isolation through a switch located on the main wall of the facility. The Soma 1kW wind turbine has been erected and placed on top of the previous Ginlong WT tower and requires integration into the facility. This involved the current WB inverter to be checked for compatibility as well as its existing parameters to be changed to allow for the new turbine to be compatible.

The SOMA turbine’s controller and dump load location inside the facility needed to be connected (Fig 3). The housing for the controller remained in its position on the main wall of the facility whilst the dump load was removed from the controller and secured inside the previous Ginlong dump load housing on the outside wall of the building. The separation of the dump resistor was needed for it posed a safety concern in its previous location. The controller and dump load were then connected via 2.5mm diameter wires to the main wall and turbine.

The Fortis Passaat turbine located to the West of the SOMA required various wind data for the creation of a power curve. The Wind Monitoring tower (WMT) located north of the turbine was recording data on the system however was not logging information over the required intervals needed to perform an adequate test which adhered to International Standards. The LabVIEW system that monitored the wind data was modified and adjusted to allow the data to be recorded to the needed specification to perform the test.

This report delves into the work required in integrating a new turbine into an existing system and the steps taken in the upgrade of the existing system. The system now allows for monitoring data to be collected in a user friendly table based on ten minute averages. A risk assessment document was compiled suggesting the possible improvements to the current maintenance of the wind turbines. The changes made to the system and investigation into the integration of a new turbine are shown in detail throughout this paper.
