Voltage source converters (VSCs) generate harmonics under unbalanced conditions. With the wider applications of VSCs, the harmonics produced by VSCs will provide new challenges of harmonic problems in the modern power system. The harmonics generated by VSCs are caused by the switching characteristics of power electronic devices and the interaction between the ac and dc sides, which is a non-linear...
The Nanpsilaao Island wind farm in Shantou power grid is taken as the object for study. First, using the actual data of the power grid and wind farm provided by Shantou power grid, with the help of the simulation and calculation tools of the PSCAD/EMTDC and MATLAB, the voltage deviation, voltage fluctuation, flicker severity, harmonics, three-phase imbalance degree are calculated based on the IEC...
