Apparatus for detecting ice or snow build-up on a wind turbine blade

摘要

An apparatus (10) according to an embodiment comprises a wind turbine (100) with a hub (104) supporting a blade (105), and a sensor (20) disposed and configured to monitor the blade (105) and to produce a respective output signal (21). A computer processor (30) disposed and configured to receive the output signal (21) of the sensor (20) executes a computer software application to facilitate comparing the output signal (21) to a predetermined value to determine whether solid water is present at the blade (105) and providing an indication of solid water build-up when solid water is present.
