Typhoons can cause significant damage to wind turbines, and this brings new problems for wind turbine design, especially the design of blades. This article describes what happened at a wind farm that suffered typhoon damage and a stop in operation of the wind turbines. The author undertook analysis of the available data and provides a discussion about the phenomena of the accident, the cause of the accident and the protective measures. As a result, the article brings forward some issues that fellow designers need to consider.
