基于负载转矩观测的风力机动静态特性模拟
Static and Dynamic Behaviour Emulation of Wind Turbine Based on Load Torque Observation
摘要
Abstract
To improve the accuracy of wind turbine emulator (WTE), the motion equations of WTE and the actual wind turbine system were analyzed. Then, an emulation strategy based on load torque feedback to reproduce both the static and dynamic behaviour of an actual wind turbine was proposed, which was deduced according to the principle of equal speed in the two systems. A sliding-mode observer (SMO) was employed to estimate the load torque used for the emulation strategy. Meanwhile, the equivalent filtering effect of SMO was analyzed. Analysis result showed that the observer result of SMO was equal to the real load torque with a first-order filter. Experimental results, using RT-LAB real time controller implementation, prove that the load torque can be observed correctly by the proposed method. Further, the operating characteristics of the wind turbine with different mechanical parameters can be emulated flexibly by the developed WTE.关键词
