Abstract

The Electrical design of the 10kW Photovoltaic (PV) Trough Concentrator System involves the use of equipment from the original Rockingham Campus PV system to achieve the aim of exporting power to the South West Interconnected System (SWIS) electrical grid.The 10kW system has been designed to all relevant Australian Standards, in particular AS5033:2005 Installation of photovoltaic (PV) arrays and AS4777:2005 Grid connection of energy systems via inverters.Using the university’s Spire Solar Simulator, all 80 of the photovoltaic receivers have been tested for functionality and degradation, and from these test results the most suitable 40 receivers in terms of power output and mismatch effects were selected and installed.
The results have been documented and placed into the university’s engineering computer directory for future reference.The test results have enabled the electrical design and configuration for the PV array to be completed with the inverter and associated electrical equipment specified.Part B of this report involved two additional projects that were undertaken. The first being the overhaul of an unsafe PV array structure that required major repairs to enable the array to be moved, and the second, the design and implementation of two new structures including fabrication and construction of new beams, bearings and gearboxes, to enable future PV arrays to be constructed for future use by engineering students.These two tasks required project management skills to liaise, communicate and supervise with contractors that were sourced for the projects. The projects were completed safely and to a high standard.The 10 kW PV array, though not yet electrically connected, has shown under concentration tests that it can produce up to approximately 80% of its rated output power when the receivers are aligned correctly.In view of the above, the PV array when connected should perform close to design specifications and should be an invaluable tool for the learning requirements of future engineering students.
