This paper investigates and analyzes the measured power-quality results of an onshore wind farm with three wind-turbine generators connected to the power grid of Taiwan Power System. The three 2-MW wind permanent-magnet synchronous generators of the studied Taichung Power Plant's onshore wind farm are connected to the extra-high-voltage bus of 161 kV through a step-up three-winding distribution transformer of 161/23.9/11.9 kV, 60/30/30 MVA. The measured results were recorded from October 8th, 2015 to November 13th, 2015 for total 37 days. The recorded power-quality results include current harmonics, voltage flickers, and voltage variations. Special output-limitation outcomes of the studied wind farm were also recorded. According to the analyzed long-term measurement results, the power-quality indices such as system frequency, voltage variations, voltage flickers based on ΔV 10 , and total demand distortion of current at the point of common coupling can meet the grid code of Taiwan Power Company.
