Applying spatial correlation filtering method to de-noise the noise of wind turbine running parameters, the stochastic volatility is eliminated. On this basis, the correlation analysis between gearbox oil temperature trend and four parameters include rotor average speed, rotor temperature, gearbox driving side bearing temperature, outside air temperature is performed. The results indicate that the correlation between gearbox oil temperature trend and rotor temperature is the highest, with gearbox driving side bearing temperature takes second place, with rotor average speed takes third place but is still large. The relationship between gearbox oil temperature trend and outside air temperature is poor.
