Impact of wind power plant on electrical power system — Comparison of calculation method and measurements

In the paper the assessment of impact of wind power plant connected to high voltage network on selected power quality indices is discussed. On the example of the Kamiensk Wind Power Plant with the installed capacity of 30 MW, a comparison of flicker indices and current and voltage harmonics calculated on the basis of data provided by wind turbines manufacturer with their values measured during the power plant operation has been performed. Some problems related to the accuracy of the assessment methods are pointed out.
