摘　　要：为了提高有源电力滤波器APF(active power filter)的快速补偿能力和安全性,设计了一种新的基于双数字信号处理器DSP(digital signal processor)APF的控制系统,其中主DSP负责模数AD(analog digital)采样、通讯、脉宽调制PWM(pulse width modulation)、继电控制和反馈,辅DSP只分担部分谐波补偿任务,两块DSP之间通过双口随机存储器RAM(random access memory)通信;提出了针对指定次谐波补偿的基于旋转坐标变换的控制策略,通过改善硬件、软件资源的合理分配,提高了APF谐波补偿的快速性和安全性。最后搭建了双DSP的APF实验环境,通过AD采样、脉宽调制,继电控制实验,验证了该控制系统的可行性、安全性。To improve the fast compensation capability and security of an active power filter ( APF ), a new control sys? tem based on dual-digital signal processor ( DSP ) is designed. The main DSP is responsible for analog digital ( AD ) sampling , communication , pulse width modulation ( PWM ), relay control , and feedback , while the auxiliary DSP only shares part of the harmonic compensation task;in addition , the two DSPs communicate between each other through a dual-port random access memory ( RAM ). A control strategy based on rotational coordinate transformation is proposed for the specified harmonic compensation. By enhancing the rational allocation of hardware and software resources , the fastness and security of APF harmonic compensation are improved. Finally , a dual-DSP APF experimental environment was set up , and the feasibility and security of the control system were verified by AD sampling , PWM , and relay control test.
