Special case - BladeTrackers leading edge inspections.
- Is your power curve suggesting leading edge erosion on your blades, but you don't want to shut down the entire windfarm and perform an all out inspection campaign?
- Is your wind turbine blade at the end of its warranty period and you want an early assessment of the leading edge?
- Do you have questions on the durability of a recent leading edge repair?
BladeTracker has developed a quick method just focusing on the leading edge. With just 6 to 8 images per blade, while your turbine remains in operation and without interfacing with the O&M department. You can assess the condition of your leading edge and end the discussion.
This service can be scheduled very quickly as there is no interface with the O&M department and no drone permits are required.
This inspection is a good starting point to quantify your annual energy production loss (AEP) by using tools like SALT*. It helps to link the observed leading edge erosion to a performance loss of the turbine. The principle of the method is to assign different erosion patters to sections of a blade. The program will calculate an overall efficiency drop of the blade.
Leading edge erosion always starts at the tip of the blade as local speeds are the highest there. Then it gradually expands towards the root of the blade. Leading edge erosion will never run fully until the root of the blade as the speeds near the root are too low, but will often stop around midway of the blade.
