Abstract

This paper reviews the current development status of drive chain test platforms based on the source of loading load, and further summarizes the six-degree-of-freedom loads experienced during the operation of the wind turbines, clarifying the standard operating conditions and external conditions that need to be considered in load calculations. Regarding the loading methods, the key technologies of torque simulation are analyzed from two aspects: high torque and high inertia. The existing non-torque load simulation technologies at home and abroad are summarized, and four typical non-torque loading schemes are summarized. To address the nonlinearity and parameter uncertainties in non-torque hydraulic loading systems affecting loading accuracy, common methods for enhancing loading accuracy and frequency response are introduced, as well as the cutting-edge development directions of digital multi-cylinder loading and guided static pressure loading. The drive chain testing platform plays a crucial role in the design and reliability improvement of the wind turbine. With the development of wind energy utilization technology, virtual prototype technology is expected to become a new development trend for future test platforms to reduce research and development costs and shorten research and development cycles.
