When you turn on the power switch, light up your home lights , perhaps from wind power . XJ Group developed the production of 2 MW series of double -fed induction wind turbine, a wind turbine operating at full load , one hour power 2000 degrees , ordinary citizens can make a family to spend a year .
Today, there are four such wind turbines in Sanmenxia and running and successful national power grid . Nanyang city side wind farm, Pingdingshan Ye County wind farm, under preparation. Three wind farms put into operation, will change the situation in Henan coal-fired power dominate the political arena .

To solve the problems on the ground
April 11 , Xuchang City, Henan Zhongyuan Electric Gu XJ wind power technology companies , 36,000 square meters large production workshop , stocked with a Taiwan and Taiwan being assembled by 2 MW doubly fed induction wind turbine series . Workshop northwest corner , is a full power test control center.
"Om - " accompanied by the roar of the motor , a wind turbine factory coming from two large traction motor rotation .
"Now do is idling test , mainly to see the fan rotating parts have various abnormalities ." Qiao Xiaoguang said the person in charge of the center , but also for the subsequent testing and full power grid test .
Our daily use of electricity is alternating current for the electricity standard frequency is 50 Hz. Fan the electricity is only stable at 50 Hz , talent and national power grid . Qiao Xiaoguang metaphor , like an electric fan issue tables, a second turn 50 laps , while the watch is also a second grid turn 50 laps , two tables only fully synchronized , and the two share power in order to synthesize one , otherwise there will be a short circuit grid accident .
To test for two days , the wind turbine factory , a comprehensive physical examination . Qiao Xiaoguang said blower host weight 68 tons , the installation should hang up to 80 meters above the ground , lifting one time fee only need $ 200,000, thus lifting the front must be foolproof , to solve the problems on the ground .
