Abstract The quantitative analysis of wind turbine blade icing is the basis of understanding and solving the icing problem. Considering that there is little research on this at home and abroad, in this paper, the artificial icing test of small wind turbine is carried out in the multi-functional artificial climate laboratory, the blade icing types under three icing conditions such as rime, hard rime and soft rime are obtained, and the icing results are deeply analyzed; At the same time, a relatively perfect blade icing calibration method is given to realize the quantitative analysis of blade icing, and then its practical application is analyzed. The results show that the icing is concentrated in the leading edge of the blade, and the icing range near the stagnation point of the airfoil surface is about 11% of the chord length of the blade; The icing showed a linear growth trend in the blade span-wise direction, accounting for about 70% of the blade length, and the icing was more obvious in the area of about 30%~40% of the blade length near the blade tip. Therefore, the leading edge area formed by the section airfoil surface near the blade tip with about 30%~40% of the blade length and occupying 11% of the blade chord length can be taken as the key research area, that is, in practical application, it can be designed as the best icing protection area and the setting area of blade icing thickness monitoring points. The research results of this paper can provide data reference for solving the problem of fan icing.
