Abstract

Three-phase harmonic measurements of a group connected generator-HVDC power converter unit were recently carried out at the Benmore end of the New Zealand HVDC link. This paper describes the test measurement procedures, the set up and configuration of the CHART instrumentation and presents the results which include measured waveforms and their harmonic contents in sequence components for a range of DC line currents. Dynamic simulation accurately predicts the harmonic current contents. The generator harmonic impedances are estimated from the measured and simulated terminal voltages and currents. The generator harmonic ratings for direct connections are also investigated
