摘 要:为提高有源电力滤波器(Active Power Filter, APF)的补偿性能,提出了一种基于双DSP的三电平APF控制器,改善了资源分配,主DSP负责负载电流采样、补偿电流采样、直流侧电压采样、谐波及无功补偿电流提取、电流跟踪控制运算、PWM波调制等工作,辅DSP负责分担部分运算和信号采样,包括谐波运算、电网电压采样、触摸屏显示、断电数据存储等,2块DSP之间通过双端口随机存储器RAM通信;更加合理地分配了软件任务,提高了双DSP并行运算能力。并且在三电平APF实物中进行了验证,可实现开关频率20 kHz,电网电流畸变率可以从15%治理为2%,谐波滤除率达86.7%,具有良好的谐波滤除能力。To improve the compensation performance of Active Power Filter(APF),this paper proposes a three-level APF con-troller based on dual DSP,which improves resource allocation.The main DSP is responsible for load current sampling,compensation current sampling,DC side voltage sampling,harmonic and reactive compensation current extraction,current tracking control calcula-tion,PWM wave modulation,and other tasks,while the auxiliary DSP is responsible for sharing some operations and signal sampling,Including harmonic calculation,grid voltage sampling,touch screen display,power outage data storage,etc.,communication be-tween the two DSPs is achieved through dual port random access memory RAM;More reasonable allocation of software tasks has im-proved the parallel computing ability of dual DSP.And it has been verified in a three-level APF prototype that it can achieve a switc-hing frequency of 20 kHz,reduce the grid current distortion rate from 15%to 2%,and achieve a harmonic filtering rate of 86.7%,demonstrating good harmonic filtering ability.
