Analysis on the Influence of Near Zone Operation Mode on Harmonics of Converter Stations
The correlation between harmonics of converter stations and operation mode of main plants near the converter station is analyzed.The fluctuation of AC-side fifth-order harmonics and DC-side sixth-order harmonics and the action principle of DC filter capacitor's overload protection alarm are analyzed.By analyzing the on-site harmonic monitoring data and the change of the operation mode of near-zone important plant,the emergent handling strategy for harmonic monito-ring and DC filter capacitor overload protection alarm is proposed.The proposed measures has been verified effective in im-proving DC harmonic disposal capability and safe and stable operation level of HVDC systems.
