基于TMS320F240的混合有源电力滤波系统软硬件设计

在现代电力系统中谐波污染问题日益突出,电网电力谐波治理有重要意义。采用单片机控制时系统实时处理要求不能得到很好满足。该文介绍了一种并联型混合有源电力滤波系统的构成和工作原理。基于TMS320F240DSP开发套件,给出了系统硬件设计电路,采用脉宽调制(PWM)定时器下溢中断工作方式,设计控制系统主程序和中断服务子程序,采用TMS320F240DSP汇编语言编程方便和直观,运算精度高,控制器参数调整方便,易于实现各种控制策略。

The Design of Software and Hardware of Hybrid Type Active Power Filter Based on TMS320F240 DSP Processor

In modern power systems the problem of harmonic pollution becomes worse and it is significant to resolve power network harmonics.When controlling by single -chip microcomputer it can not satisfy the system demand of treatment on time.The configuration and working principle of a hybrid system of shunt active power filter is introduced.Based on TMS320F240DSP exploiture tool the hardware design circuits are given.The main program and interrupt subprograms are designed by using PWM timer underflow interrupt manner.It programs easily and intuitively,operates precisely,adjusts parameters expediently,and realizes easily all kinds of control tactics applying the assembly language of TMS320F240DSP.If the control object is changed,adjusting some parameters of control algorithm can meet the parameter require.
