摘要：

The problem of deriving equations of motion that describe the coupled tower-rotor system of a wind turbine is discussed. The mathematical formulation of these equations is described first in a form suitable for manual derivation and then as a step by step process suitable for automation. Reasons for and experience in using a symbolic computing system to undertake this work for large models are described. The general approach is illustrated by means of a very simple model. Finally, some results of the stability analysis of the simple example and an eleven degree of freedom three-bladed model are presented together with a set of measured and predicted blade loads for a 250kW wind turbine.
