摘要: 非线性电路与系统是非线性科学的一部分，目前以经受到各个领域的关注。本文研究了风力发电并网中带有随机白噪声和非线性扰动的同步控制问题。利用基尔霍夫定律得到了风力发电系统电网侧变流器的数学模型。设计了适当的自适应同步控制器，借助李雅普洛夫稳定性理论，验证了该同步控制器的有效性。进一步消除由于电流并网产生的非线性及随机扰动，使得风力发电机所产生的电流和电网所产生的电流同步。最后通过Matlab中的Simulink进行了仿真设计研究，验证了该理论结果的有效性。 Nonlinear circuits and systems are parts of nonlinear science, which have been central issues in various kinds of research fields. In this paper, we studied the synchronization control of wind power with disturbance of nonlinearity and white noise. By using the Kirchhoff’s law, we obtained the mathematical model of wind power grid side converter system. Meanwhile, an appropriate adaptive synchronization controller was designed. By establishing a suitable Lyapunov function, we validated the effectiveness of synchronous controller. Therefore, we can eliminate the disturbance of nonlinearity and white noise produced by the wind current embedding into the grid. As a result, we can make the current generated by the wind generator synchronize the current in the grid. Finally through Simulink in Matlab simulation, we validated our theoretical results.
