摘要
建立60°坐标系,经过标幺变换,使基本矢量转化为标幺值,并且通过旋转矩阵,将其他扇区旋转到第1扇区,基本矢量作用时间固定,大大简化了运算方法,优化运算流程。在Matlab/Simulink环境下搭建三相并联型APF仿真模型和实验验证,结果表明基于60°坐标系下有源滤波器SVPWM优化算法在保证系统稳态精度的同时有效改善了系统的动态响应性能。
Puts forward a kind of 60 coordinate system that can make the basic vector into the per unit value by the value-unit transformation.And through the rotation of the matrix,can rotate the other sectors to the first sector in order to fixthe time of basic vector function. This method greatly simplifies the computation method and optimizes the operation process. Can set up the three-phase shunt APF simulation model based on Matlab simulation platform. And the results show that based on 60° coordinate system,the SVPWM optimization algorithm of active filter guarantees the steadystate accuracy of the systemand at the same time effectively improves the dynamic response performance of the system.
