Abstract: This paper describes the automatic error correction in the field of blade lowering and raising in a wind turbine where we already optimized the process of blade replacement using optimized technology [1] by eliminating the usage of heavy-duty cranes. By means of utilizing Ultrasonic, LiDAR, hall effect and loadcell sensor, we eliminate the chances for error in the operation of multiple winches simultaneously. Load shared by each winch can be identified using the loadcell sensor and provide feedback to the controller to correct the errors in the winch operation. Hall effect sensor is used to ensure that the winches are operating at proper pulses. The ultrasonic and LiDAR sensor is used to monitor the displacement of the blade while lowering and raising to protect the blade from the impact
