GPS disciplined oscillator for long-term synchronized harmonic measurements

Measurement process is one of the most important issues during wind turbine generator (WTG) and wind power plant (WPP) evaluation and requires careful approach. Accurate measurements of harmonic voltages and currents in offshore WPPs followed by proper data analysis are … Continue reading

Active filtering vs. passive filtering

Let us think about various sources of harmonic problems in large wind power plants (WPPs) and different ways of optimized harmonic mitigation methods. We discussed previously about harmonic problems such as sources of harmonic emission and amplification as well as … Continue reading

Harmonic problems in wind power plants

Harmonics has always been of special concern in power system studies. In the past the power system comprised mainly of passive components with relatively linear operating range and synchronous generators. Harmonic analysis of such systems is the state-of-the art right … Continue reading
