Embodiment Construction

[0028] Figure 1A A schematic diagram of a wind turbine blade ice accretion detector 65 is shown in . It can be implemented on small wind turbines for domestic or light utility use, but is mainly used on large wind turbines such as those suitable for large-scale power generation eg on wind farms. In this case, the diameter of the rotor can be as large as 100 meters or more. The wind turbine blade ice accretion detector is configured to receive indications from the wind turbine in the form of electrical signals including: the power produced by wind turbine 67 ; the environmental conditions of wind turbine 69 ; and errors associated with wind turbine 71 . As described in more detail below, it processes these indications or information to provide an indication of ice accretion on the wind turbine blades in the form of electrical signals. This indication is output from output 73 .

Abstract

A wind turbine blade ice accretion detector 65 is configured to receive an indication of power generated by a wind turbine 67 and an indication of a plurality of environmental conditions of the wind turbine 69. It is also configured to receive an indication of an error relating to the operation of the wind turbine 71. These indications are processed by the detector 65 to provide an indication of ice accretion of a wind turbine blade. In addition to or as an alternative, the wind turbine blade ice accretion detector 65 is configured to receive an indication of power generated by a wind turbine 67 in a plurality of different time periods and an indication of a plurality of environmental conditions of the wind turbine 69 in the plurality of different time periods; and to process these to provide an indication of ice accretion of a wind turbine blade.

Description

technical field [0001] The invention relates to a wind turbine blade ice accumulation detector and a method of detecting ice accumulation on at least one wind turbine blade. Typical wind turbines to which the detector and method are adapted are used, for example, for large-scale power generation on wind farms. Background technique [0002] figure 1 A typical known wind turbine 1 for large-scale power generation on a wind farm is shown. The wind turbine comprises a wind turbine tower 2 on which a wind turbine nacelle 3 is mounted. A wind turbine rotor 4 comprising a plurality of blades 5 is mounted on a hub 6 . The hub is connected to the nacelle by a low speed shaft (not shown) extending from the front of the nacelle. [0003] During normal use in cold climates, ice can build up on wind turbine blades under certain climatic conditions, which can cause a number of problems. The power generation performance of a wind turbine may be adversely affected as ice may affect the...
