Abstract
In this thesis, the inverter control is exploited in order to limit the fault current contributed by the photovoltaic distributed generation interconnected with the distribution feeder. Numerical and experimental setup of the photovoltaic and its inverter are accomplished in order to verify the proposed fault current limiting performance. The limiting characteristic is determined as a function of the inverter voltage dip. Achievement of the thesis objective is realized via conducting an efficient emulation of the real photovoltaic modules in the laboratory supported with experimental measurements and analyses. An experimental emulator is proposed and constructed for the photovoltaic array. Theoretical and experimental characteristics of the constructed emulator are compared which validate the successful profiling of the photovoltaic module. As test cases for normal operation, the proposed photovoltaic model is examined under grid-connected operation with the desired levels of the active and reactive powers being supported from the photovoltaic model. With these configurations, fault current limiting concept is introduced and applied using the controlled inverter without any additional hardware device or modification. Simulation platform of the proposed work is developed using MATLAB program. Experimental setup is carried out with the facilitated equipment including inverter unit and DSPACE 1104 board as a controller unit to verify the proposals. The study discusses the photovoltaic, as a distribution generation (DG), impact on the recloser-fuse coordination using a typical 11 kV overhead distribution feeder. The results of the introduced fault current limit methodology provide evidence about the effectiveness of the proposed fault current limiting scheme. Therefore, mal-operation of the protection system due to the addition of the photovoltaic (PV) as a distribution generation (DG) has been avoided without any changing in the existing protection coordination or addition of further equipment to limit the fault current.
