STATISTICAL ANALYSIS OF THE RESULTS OF MEASUREMENT OF WIND SPEEDS

Abstract

One way of research activity in the wind’s energy field is correct assessing of wind’s energy potential. Today is increasing the necessity of identifying the most perspective places for generate wind electricity, considering main feature of wind power - the unevenness of manifestation in time and space, which based on the frequency and direction repetition of wind. Objective of the study is determination the repeatability of wind speed and direction, which based on measurement of wind speed in Kyiv in 2013. Was performed a statistical analysis of wind speed measurements in Kiev using a differential distribution and Weibull statistical function. Were established preferred directions of the wind during the year and seasons. Was performed relation between power density production of wind energy and wind speed recurrence. The predominant wind directions for Kyiv in 2013 were north and west in the summer and southeast in winter. Dominant annual wind direction is south with probability 0.08, north and west with probability 0.1. The most probable wind speed for southerly direction is 3 m / s, for the north - 3 m / s, and for West - 2 m / s.
