Title: Modeling of Dynamics of Driveline of Wind Stations: Implementation in LMS Imagine AMESim Software
Authors: Jiang, Bincheng
Abstract: The wind power area is booming rapidly and enormous of malfunction of wind turbine components emerges in the market. Therefore, it is time to pay attention to the quality of the design process. In the past years, the industry is a dearth of information on just what goes on in the internal workings of a wind turbine, especially for the drivetrain part. Nowadays, there is a high downtime per failure of drivetrain per year among the different components of the wind turbine due to the rigorous load impacting from the rotor hub and the generator or electrical network faults. The thesis work is kind of pre-study of analyzing the dynamic performance of drivetrain in the wind power station. It is a tentative effort to study the dynamic behavior of the gearbox under normal operation and transient load condition in order to be ready to dig out the reasons of the drivetrain misalignments in the future work. The main objective of the present thesis is to develop the 1-D torsional multibody dynamic model of the drivetrain of wind station taking into account excitation from the aerodynamic force and the response from the generator part of the wind turbine. Furthermore, it is of importance to understand the principal concept of modern wind turbine, especially the typical drivetrain configurations; the modeling approaches and how to build the model for the aerodynamic force and generator torque in AMESim, also how analyze the dynamics of drivetrain. The aim is to analyze the torsional dynamics of wind drivetrain, consisting of free response vibration, transient vibration dynamics and the steady state simulation for the calculation of power losses. Linear analysis is applied for the cases of free vibration and transient torsional dynamics, such as eigenfrequencies, mode shapes etc.
