A Power Quality Instrument for Harmonics Interharmonics and Amplitude Disturbances Measurements
نویسندگان
چکیده
− In the last years the increased interest about power quality, forced international working groups to define new standards for testing and measurement techniques. In this paper a pc-based power quality instrument is proposed, according to IEC 61000-4-7 and standard IEC 61000-4-30. It is a low-cost and easily reconfigurable instrument able to measure harmonics, interharmonics and amplitude disturbances and supply unbalance. The complete instrumentation has been tested using standard test procedures in order to verify its accuracy limits.

متن کاملCompressed Sensing High-accuracy Detection for Electric Power Interharmonics
Interharmonics frequencies are not integer multiple of the fundamental frequency, and interharmonics amplitudes are far less than fundamental amplitude and harmonics amplitudes, which mean high sensitivity to desynchronization problems, so it’s dificult to estimate interharmonics. In this paper, a new method based on random sparse sampling and compressed sensing (CS) Bregman technique was propo...
متن کاملWind Power Harmonic Emission versus Active-Power Production
Modern wind turbines are commonly equipped with power electronics. The application of either a partial scale frequency converter or a full scale power converter will result in harmonic emission which is distinct from conventional harmonic sources: even harmonics and interharmonics appear with similar magnitudes as odd harmonics. Harmonic and interharmonic measurements on a few individual wind t...

متن کاملHarmonics Estimation in Power Systems using a Fast Hybrid Algorithm
In this paper a novel hybrid algorithm for harmonics estimation in power systems is proposed. The estimation of the harmonic components is a nonlinear problem due to the nonlinearity of phase of sinusoids in distorted waveforms. Most researchers implemented nonlinear methods to extract the harmonic parameters. However, nonlinear methods for amplitude estimation increase time of convergence. Hen...
