Abstract

Disclosed is a method for detecting a pitch angle of a wind turbine generator set. In this method, a base pitch angle in each target time period is determined based on an actual active power in the target time period, and warning information is sent in a case that it is determined that an abnormal time period in which a variation between the base pitch angle and the actual pitch angle is greater than a variation threshold is present in a plurality of time periods.
