Abstract

We consider a small device for converting the medium’s flow energy, which is designed based on the use of a crank mechanism. A blade interacting with the flow is fixed on the connecting rod of the mechanism and the crank shaft is connected to the electric generator’s rotor. The system has a control input that allows us to control how much of the energy taken from the flow is converted into electricity. It is assumed that such control is carried out by changing the total external resistance in the local circuit of the electric generator of the device. The dependence of the average mechanical power in the steady-state operating modes on the gain of the control action is described. The effect of the flow rate, the dry friction coefficient in the mechanism slider, and other model parameters on this dependence is investigated. To construct the corresponding bifurcation diagrams, we use a numerical-analytical iterative method for generating periodic motions with the specified properties, which develops the Andronov–Pontryagin approach.

控制铰链式风力发电机的运行模式

摘要

我们考虑一种基于曲柄机构设计的用于转换介质流动能量的小型设备。与流体相互作用的叶片固定在机构的连杆上，并且曲轴连接到发电机的转子。该系统具有控制输入，允许我们控制从流中吸收的能量转换为电能的量。假定通过改变设备的发电机的本地电路中的总外部电阻来执行这种控制。描述了稳态操作模式下平均机械功率对控制作用增益的依赖性。研究了流速，机构滑块中的干摩擦系数以及其他模型参数对此依赖性的影响。
