State Characteristic Parameters Extraction Method of Wind Turbine Blades Based on the Length Fractal Dimension
According to characteristic of wind turbine vibration signal, base on the length fractal dimension principle, carry out quantitative description of length fractal characteristics to nonlinear signals on the fault generated by the wind turbine blades. The test and calculation results show that when the different wind turbine blades failures occur, the length fractal dimension value appear clear rules. Therefore, we can use the length fractal dimension effectively extract the fault character parameters of wind turbine blade.
