Analysis of electric power quality

This paper deals with standard and legal requirements concerning electric power quality produced by wind power plants and with conditions under which electric energy transmission in the national electric power system can take place. The electric energy quality assessment is based on the case of Kamiensk Wind Power Plant and takes into consideration the following indices: variation in supply voltage, light flickering as well as distortion and asymmetry of voltage by higher order harmonics. Following the conducted measurements, it has been observed that the parameters of electric energy quality comply with current regulations in the Common Connection Point (CCP) of the power plant electric network with the public power system 110 kV.
