Gale Change and Grading for Power Grid Wind Zone in Jiangsu Province
ieee conference energy internet and energy system integration(2019)
摘要
In this paper, the data of Jiangsu gale stations in lately 50 years is analyzed, and temporal-spatial variation characteristics of gale in this region is revealed. Firstly, type I extreme value distribution probability model is used to calculate the statistical wind speed values of the meteorological stations in Jiangsu Province and is completed maximum wind speed statistics of 30-year and 50-year return period for Jiangsu power grid. Then the grading standards of wind zone in Jiangsu power grid is also discussed for giving the wind-distribution map of power grid and its application principles and recommendations, so as to provide technical support for wind disaster prevention of overhead transmission lines of Jiangsu power grid.
