【摘要】：在高压系统对谐波治理需求不断增加的背景下,基于三电平逆变电路的有源电力滤波器得到了迅速发展,人们对三电平有源电力滤波器的谐波电流跟踪补偿技术的研究越来越重视。针对目前常用的基于电压定向PI整定控制法存在PI参数难以整定、动态控制性能不理想等不足之处,提出基于情感智能控制的谐波电流跟踪控制算法,利用情感智能控制的PI参数自矫正能力和变结构特性来克服上述问题。基于Matlab/Simulink的仿真结果表明,该控制算法使三电平有源电力滤波器的输出纹波较小,谐波含量低,具有较优的动、稳态性能。
[Abstract]:Under the background of increasing demand for harmonic control in high voltage system, active power filter based on three-level inverter circuit has been developed rapidly. More and more attention has been paid to harmonic current tracking compensation for three-level active power filters. Aiming at the shortcomings of the current voltage oriented Pi tuning method, such as difficult to adjust Pi parameters and unsatisfactory dynamic control performance, a harmonic current tracking control algorithm based on emotional intelligent control is proposed. The Pi parameter self-correcting ability and variable structure characteristic of affective intelligent control are used to overcome the above problems. The simulation results based on Matlab/Simulink show that the proposed control algorithm makes the output ripple of three-level active power filter small, the harmonic content is low, and the three-level active power filter has better dynamic and steady-state performance.
