750kW 풍력발전기 현장시험을 통한 하중 비교

Load comparison of 750kW WTGS by field test

This study proposes an essential process of type certificate, which is load comparison for proving the calculated design load. The load measurement was carried out according to IEC 61400-13 standard and the load calculation was performed with same condition using FLEX 5 code. For more accurate load simulation, the controller parameter of original model at the design stage was modified to site optimized value and some node points are added to coincidence with measurement. The load comparison was performed with various wind parameter, turbulence intensity and wind shear. As a result, simulated loads ware good agreed with the measured load. Therefore, the calculated design loads according to IEC 61400-1 standard were proved to valid.
