风力发电系统中金属带式无级变速器对运转特性影响研究 by 李刚

“…For constant ratio for traditional wind power system with low energy utilization and poor adaptation to the external environment,the metal belt CVT is introduced as a part of traditional wind power system,the eventual of a new variable ratio wind power system is established,through numerical modeling method,the model of the new variable ratio wind power systems is built,the variation law of system parameters,performance indicators before and after introduction the metal belt CVT into wind power system is studied.The results show that metal mounting system CVT wind speed changes in the external conditions,overall power coefficient,turbine power,electric power delivered,the torque transmission shaft and energy efficiency are higher than the system is not installed,since the introduction of the metal belt CVT,the drive shaft torque before the changes become smoother than the installation,which has direct implications for increased torsional fatigue life of the drive shaft.The energy efficiency of installation metal CVT wind power system wind conditions at each interval change in energy efficiency compared to not install the system is small,stable energy output.…”

Drought prediction based on an improved VMD-OS-QR-ELM model. by Yang Liu, Li Hu Wang, Li Bo Yang, Xue Mei Liu

“…To overcome the low accuracy, poor reliability, and delay in the current drought prediction models, we propose a new extreme learning machine (ELM) based on an improved variational mode decomposition (VMD). The model first redefines the output of the hidden layer of the ELM model with orthogonal triangular matrix decomposition (QR) to construct an orthogonal triangular ELM (QR-ELM), and then introduces an online sequence learning mechanism (OS) into the QR-ELM to construct an online sequence OR-ELM (OS-QR-ELM), which effectively improves the efficiency of the ELM model. …”
