Systems and methods for identifying wind turbine performance inefficiency

Abstract

The present disclosure relates to an approach by which low-performing turbines (60) may be identified from among a plurality of wind turbines, such as may be present at a wind power plant (50). In accordance with one embodiment, low-performing turbines (60) are identified from among pairs of turbines (56) and based upon a comparison of the observed (76) and expected performance (80) of the turbines within each pair.

Description

technical field [0001] The subject matter disclosed herein relates to systems and methods for evaluating wind turbine performance, such as at a wind farm. Background technique [0002] Wind turbines typically include a plurality of blades extending from a central hub. The hub is rotationally coupled to a nacelle suspended above the ground by a tower. Typically, the nacelle houses an electrical generator coupled to the hub and configured to generate electrical power when the blades are rotated by the wind. Wind turbine blades are typically designed and manufactured to efficiently convert wind energy into rotational motion, thereby providing sufficient rotational energy to a generator for generating electricity. [0003] A wind farm typically includes a number of wind turbines of this type distributed over a given geographical area. Wind passing through the region causes the blades associated with each wind turbine to rotate, thereby generating electrical power. In such wi...
