Abstract

Disclosed is a method of monitoring relative blade pitch angle alignment of a set of at least two rotor blades in a rotary device. The rotary device may be a wind turbine generator. Also disclosed are operational schemes based on the observed relative blade pitch angle alignments.

Description

technical field [0001] A method of monitoring relative blade pitch alignment of a set of at least two rotor blades in a rotating device is disclosed. The rotating device may be a wind turbine generator. An operational scheme based on the observed relative blade pitch angle alignment is also disclosed. Background technique [0002] The performance of a rotating device with blades depends on the state or condition of the blades. The blades can be pitched or at a pitch angle. This pitch or pitch position may be aligned as expected, or there may be a difference or misalignment. This misalignment, difference or difference may be an absolute value for an individual blade. Thus, there is absolute misalignment. There may be a misalignment, discrepancy or discrepancy between the two blades. There is thus a relative misalignment. [0003] Pitching blade alignment or misalignment is an area of ​​technical importance for any rotating device with blades. A blade may have an overa...
