摘要
近年来,SVPWM技术已应用到有源电力滤波器(APF)的控制策略中,传统的基于APF的SVPWM控制算法由于复杂的三角函数计算和矢量扇区判断,为产生补偿信号需要很大的计算量,导致动态补偿响应减慢,对此提出一种改进的基于dq坐标系的SVPWM电流控制算法,优化空间矢量作用时间,避免复杂的三角函数计算和矢量扇区判断过程,减少了SVPWM算法的计算量。仿真和实验结果验证了该算法的正确性。
In recent times, SVPWM technique was applied for active power filter （APF） control strategy. The conventional SVPWM based on APF has high computational burden due to complex trigonometric calculations and sector identification involved to generate the compensating signal, hence the response for compensation is slow. In this paper, an improved SVPWM technique based on dq coordinate system is presented based on the effective time concept. The effective time concept eliminates the trigonometric calculations and sector identification, thereby it reduces the computational effort. Simulation results demonstrate the efficacy of the APF with the improved SVPWM.
