Sažetak
In this paper a low-budget single-phase voltagewaveform simulator based on the NI PCI-6071E DAQ card anddesktop PC with real-time Phar Lap operating system has beenpresented. Program for generating waveforms in accordanceto the IEC standard 61000-4-13, with harmonics of variablefrequency, amplitude and phase, has been implemented in theLabVIEW RT environment. Calibration of DAQ card internalclock has been performed to increase the accuracy of the gener-ated voltage waveform frequency. In order to achieve consistentsystem operation, DAQ card internal temperature sensor hasbeen used to compensate clock frequency drift caused by localambient temperature variations. For verification purposes, oneof algorithms for the frequency estimation based on the linearKalman filter has been deployed to target PC. Experimentalresults in steady-state and dynamics have also been presented.The estimated frequency of the generated signal matches verywell with the values obtained by the digital multimeter used forcalibration procedure.
