The Integration And Development Of Full System Loads Analysis And Optimization Design Of Wind Turbine Software

This article has established Equilibrium Wake model and Dynamic Wake model based on the theoretical basis of steady aerodynamic performance calculation of the rotor, which accounts for Wake's influence on the rotor in the operation process of horizontal axis wind turbine(HAWT). And it has realized dynamic aerodynamic calculation module for the rotor. With the Visual C++ development tool, based on the theory model, it has achieved development, test and integration of Full System Loads Analysis and Optimization Design of Wind Turbine Software (BladeDesign for Windows 2.1) whose functional modules include wind field, aerodynamic calculation, transmission system, control system and structural dynamics. In the thesis, two sections are mainly included: one is the analysis and establishment of wake model, the other is the integration and development of Full System Loads Analysis and Optimization Design of Wind Turbine Software.The wake model includes Equilibrium Wake model and Dynamic Wake model. Considering the wake influence of blades, based on steady aerodynamic calculations theory, Equilibrium Wake model corrects the simplified model of aerodynamic calculations for the rotor. Considering the process of dynamic influence of eddy flow at every section of blades, based on Equilibrium Wake model, Dynamic Wake model simulates the dynamic aerodynamic calculations for the rotor.The integration and development of Full System Loads Analysis and Optimization Design of Wind Turbine Software, based on aerodynamic performance and structure CAD software of HAWT, is developed by the Object Oriented Programming means. The functional module of software is divided into the wind field, aerodynamic calculations, transmission system, control system, structural dynamics analysis modules and the interface by its actions. According to the coupling relations of various functional modules, the union input and output interfaces are provided. And those functional modules are encapsulated and integrated into the software (BladeDesign for Windows 2.1). So it extends the function of aerodynamic...
