Abstract:In this paper, power curves of different types of draught fans are accurately and rapidly measured using laser radar anemoscope. After that, a quantity standard disposal to the power and a comparative analysis of power curves refer to IEC 61400-12-1—2015 criterion are conducted, which confirm the optimal draught fan type and provide a reference for draught fan performance evaluation and wind power unit selection.
