This document outlines the components and testing procedures for a wind turbine test station, including testing the mechanical and air brakes for safety, measuring the power curve and efficiency, analyzing structural integrity by measuring eigen frequencies and response during operation, assessing electrical cut-in performance, and evaluating transmission efficiency, rotor performance, and yaw error statistics. The test station acquires and analyzes performance data from the wind turbine and its various systems to ensure it is functioning properly and meeting design specifications.
