    Recently, blade extension wing technology has been applied
    for the first time in China.
    On July 12, the first domestic blade extension wing project test unit was put into operation
    in the Laizhou Tangzhen Wind Farm of New Energy Shandong Company.

    The blade extension wing technology independently designed and produced by the New Energy Test and Research Institute is to extend the airfoil at the tip of the blade without disassembling the original blade, so that the impeller diameter is increased from 77 meters to 80 meters, and the sweeping area is increased by 117.
    75 square meters, which effectively improves the power generation capacity
    of the existing units.

    Since this technology is the first application in China, in order to ensure the safety of the unit, strict theoretical calculations and ground model tests
    were carried out before the transformation.
    On the first day of operation, the unit experienced the test of strong wind, the instantaneous maximum wind speed reached 14 m/s, and the instantaneous maximum power of the unit reached 1547 kW
    .
    After two days of data analysis, the vibration, pitch torque and temperature of the unit were all within the normal range
    .

    Blade extension wing technology will effectively solve the mismatch between the design wind speed of the unit and the local wind resources, and has strong technical and economic competitiveness
    compared with other efficiency improvement methods.
