Problems solved by technology

Therefore, it is often difficult to visually detect ice accumulation on rotor blades
Additionally, performing such visual inspections of rotor blades is often time consuming, unnecessarily increasing the amount of time a wind turbine is shut down to check for ice accumulation

Abstract

A system and method for detecting ice on a rotor blade of a wind turbine are disclosed. In one embodiment, the method may include pitching the rotor blade across a range of pitch angles, monitoring an ice-related parameter of the wind turbine as the rotor blade is pitched and comparing the monitored ice-related parameter to a predetermined baseline profile for the ice-related parameter.

Description

technical field [0001] The present invention relates generally to wind turbines, and more particularly to a system and method for detecting ice on wind turbine rotor blades. Background technique [0002] Typically, a wind turbine consists of a tower, a nacelle mounted on the tower, and a rotor connected to the nacelle. A rotor typically includes a rotatable hub and a plurality of rotor blades connected to and extending outwardly from the hub. Each rotor blade is spaced around the hub to cause the rotor to rotate, converting the kinetic energy of the wind into usable mechanical energy and subsequently electrical energy. [0003] Under certain atmospheric conditions, ice may accumulate or accumulate on the rotor blades of a wind turbine. As the ice layer that accumulates on the rotor blades thickens, the aerodynamic surface of the blades changes, reducing aerodynamic performance. In addition, ice accumulation can significantly increase the weight of the rotor blades, which ...
