Power Quality

From Wind wiki

If wind turbines generate perfect power quality, it means that the voltage is continuous and has a constant amplitude and frequency. Power quality refers to the physical characteristics and properties of electricity generated by wind turbines. Power quality is described through voltage, frequency, and interruptions.

There are various factors that affect the quality of power. Electrical grid-connected wind turbines have an effect on it as the rate of interaction between the grid and the wind turbine makes the power output varied. For example, large power systems which have high quality grids exhibit a very stable frequency. Power systems on autonomous grids, which make use of diesel engines however, show frequency variations.

In determining power quality, there are several factors required stated in national and international standards. These requirements include the following: voltage fluctuations, flicker, harmonics, transients, and frequency.
