基于DSP的数字电能质量控制器硬件设计

Digital PQC Hardware Frame Based on the DSP

通过对目前有源滤波器和电能质量控制器设计方法的比较和分析,提出了一种以DSP芯片TMS320LF2407为微控器的电能质量控制器的设计方案.利用该芯片强大的运算功能以及片内集成的事件管理器外设可以很方便的实现实时的谐波抑制、无功补偿、负荷平衡和降低电压闪变等功能.另外,利用该芯片的丰富片内外设以及电路中选择的智能驱动芯片,为控制器扩展了许多辅助功能,如过电压、过电流、串口通信等.该方案减小了电能质量控制器的设计复杂性和设计成本,对于电能质量控制器的产品化设计具有借鉴意义.

After fully understanding the principle and the design method of the active wave filter and the power quality controller,this paper brings forward a kind of design plan of the power quality controller based on the chip TMS320LF2407,which can real-timely realize in controlling of the harmony wave suppression、var compensation、balancing power load and reducing fluctuation and flash of the voltage etc.In addition,this plan also utilizes fully the chip resource and a kind of intelligent drive chip in the device for developing more auxiliary functions such as overvoltage protection,overcurrent protection and serial communication ect.This design can reduce complication and cost of the design of the power quality controller.It has positive reference meanings on the commercial design of the power quality controller.
