Allocated Harmonic Quantities As The Basis For Source Detection, Timothy Browne, Sarath Perera, Victor Gosbell
Allocated Harmonic Quantities As The Basis For Source Detection, Timothy Browne, Sarath Perera, Victor Gosbell
Associate Professor Sarath Perera
A considerable body of literature examines assessment, from measurements, of whether it is the network or a customer installation which makes the greater contribution to harmonic distortion at a point of common coupling. However, the customer contribution to harmonic distortion at a point of common coupling depends heavily upon the definition chosen for that contribution. For example, expressing contributions as currents instead of voltages or vice versa may lead to large changes in results. Further, it can be shown that the harmonic voltage at the point of common coupling cannot be expressed independently of the network conditions, meaning that the …
Voltage Unbalance Emission Assessment In Radial Power Systems, U Jayatunga, S Perera, P Ciufo
Voltage Unbalance Emission Assessment In Radial Power Systems, U Jayatunga, S Perera, P Ciufo
Associate Professor Sarath Perera
Voltage unbalance (VU) emission assessment is an integral part in the VU-management process where loads are allocated a portion of the unbalance absorption capacity of the power system. The International Electrotechnical Commission Report IEC/TR 61000-3-13:2008 prescribes a VU emission allocation methodology establishing the fact that the VU can arise at the point of common connection (PCC) due to upstream network unbalance and load unbalance. Although this is the case for emission allocation, approaches for post connection emission assessment do not exist except for cases where the load is the only contributor to the VU at the PCC. Such assessment methods …
The Electrical Performance Of Modern Compact Fluorescent Lamps, Sean Elphick, Philip Ciufo, Sarath Perera
The Electrical Performance Of Modern Compact Fluorescent Lamps, Sean Elphick, Philip Ciufo, Sarath Perera
Associate Professor Sarath Perera
Compact Fluorescent Lamps (CFL) are highly non-linear devices which are likely to experience very high growth in penetration levels, especially in domestic environments, in Australia over the next 2 – 3 years. This will occur due to the decision taken by the Australian Federal Government to ban the sale of incandescent light globes after 2009 as measures towards meeting the needs for demand side management and climate change abatement. While CFL technology has been in existence since the late 1980s penetration levels are now increasing to a point where the total CFL load cannot be considered negligible compared to other …

Hydrogen Energy Storage For A Permanent Magnet Wind Turbine Generator Based Autonomous Hybrid Power System, Nishad Mendis, Saad Sayeef, Kashem Muttaqi, Sarath Perera
Associate Professor Sarath Perera
The Performance of a novel hybrid Remote Area Power Supply (RAPS) system consisting of a Permanent Magnet Synchronous Generator (PMSG), fuel cell system, electrolyser and synchronous condenser is investigated in this paper. The fuel cell system is used to provide power during under-generation scenarios whereas the electrolyser absorbs excess power during over-generation conditions. A synchronous condenser is incorporated into the RAPS system to provide better reactive power and inertial support. Individual controllers for each system module have been developed and implemented. A control coordination methodology is established with a view to regulate the active and reactive power balance of the …
