摘要

为提高静止无功补偿器在风电机组进行无功补偿时其整流过程的动态性能和对电网谐波的抑制能力,对系统整流过程中的控制器进行改进。首先将静止无功补偿器的直流侧和风电系统整流后的直流侧并联,然后在电压外环上,基于分数阶微积分理论设计分数阶PID控制器,并使用差分进化算法对其参数进行整定,在电流内环上,使用二自由度PID控制器来提高电流的稳定性和抗干扰能力。在此基础上在Matlab/Simulink仿真平台上搭建模型,仿真结果表明：提出的方法不仅是稳定的,而且与传统PI控制器、分数阶PID控制器以及基于差分进化优化算法的分数阶PID控制器相比,在响应速度和超调量等方面显著下降,具有较好的动态响应性能,进入稳态后的总谐波失真因素和纹波系数明显减小,提高电网对谐波的抑制能力。

Abstract

In order to improve the dynamic performance of the static var compensator in the rectification process of the wind turbine and the ability to suppress the harmonics of the power grid, the controller in the system rectification process is improved. Firstly, the DC side of the static var compensator is connected in parallel with the DC side of the rectified wind power system. Then, on the voltage outer loop, the fractional order PID controller is designed based on the fractional calculus theory, and the differential evolution algorithm is used to adjust its parameters. On the current inner loop, a two-degree-of-freedom PID controller is used to improve the stability and anti-interference ability of the current. On this basis, the model is built on the Matlab / Simulink simulation platform. The simulation results show that the proposed method is not only stable, but also compared with the traditional PI controller, fractional order PID controller and fractional order PID controller based on differential evolution optimization algorithm. The response speed and overshoot are significantly reduced, and the dynamic response performance is better. After entering the steady state, the total harmonic distortion factor and ripple coefficient are significantly reduced, and the harmonic suppression ability of the power grid is improved.
