8500kW风电场电气系统一次设计

AbstractAs a kind of clean energy,wind energy has been paid moreand more attention by all countries in the world.With thedevelopment of technology,wind energy can be converted intoelectric energy,heat energy and chemical energy,etc.Amongthem,the conversion of wind energy into electricity is toconvert wind energy into electrical energy by means of windturbines,that is,the blade of the wind turbine is driven by thewind.ingeneral,large fan speed is very low,under normalcircumstances rated speed of 20-30r/min,so we need to speedup the growth rate of the system to about 1500r/min,and thenPower generation by generating system.In China,the total windpower gradually increased,whether in coastal areas or inlandareas,in placeswhere wind power is abundant,wind farms canbe seen everywhere,and it is obvious that wind power hasoccupied an important position in China's power generationsystem.This paper describes object is wind farms,Design the numberof 10 unites wind turbines with a single capacity of 850kW.After the fan sends out the 690V electric power through the box
