The traditional reactive and harmonics compensation strategy utilizes passive components, such as switching capacitors or tuned LC resonant filters are installed at the load side. However, switching capacitors have the drawbacks of over-compensation or under-compensation, and they can not provide a continuous compensation for reactive power. Besides, the passive LC filters may resonant with grid impedance, causing detrimental resonance over-voltages, which may destroy the passive components.In this project, we designed and practically implemented the active power filter with dynamic reactive power compensation capabilities. The proposed system is composed of three analogous single-phase structures. Each unit is made of single-phase inverter in series with passive LC filter and fixed switching capacitors. The dual digital signal processor (DSP TMS320F2812) plus field programmable gate array (FPGA) architecture is used for the main controller, and another DSP is utilized for touch board interface control. Robust deadbeat current control law and software phase-locked-loop (PLL) are implemented in digital signal processors, selective harmonic elimination strategy is also achieved thanks to the fast execution capabilities of the DSP. Experimental results and field tests confirms the effectiveness of the proposed system, and the power quality of the 10/0.4kV electric distribution system is significantly improved while achieving energy saving purposes. In July 2007, the first equipment we designed and implemented has been successfully installed in the low-voltage residential distribution system in Hui Jin-Yuan substation of the Shanghai Municipal Electric Power Company, which significantly improved the power quality of the distribution system and it was working smoothly after installation. Based on the design experience of the first equipment, our team has made the second version equipment, including the updated hardware and software, which enhances the efficiency of TMS 320F2812 DSP and optimizes the control parameters. The new version of the active power filter has been successfully installed in the punching shop (TC2) of Shanghai Volkswagen (SVW) Company, which has improved the power quality of the distribution system tremendously, with an increased power factor, suppressed voltage flicker phenomenon and enhanced energy utilization efficiency. It has been verified by the field practice that the proposed active power filter can provide a remarkable economic and social benefit. 电子科技大学基于DM642的智能视频监控系统摘要：本项目实现了一个基于DM642的分布式智能视频监控系统。该系统以多块DM642图像处理传感器板卡为核心，通过PCI总线与服务器主机进行交互；在用户主机端，管理员通过规则管理软件设置监控规则，DM642按照所设规则对模拟摄像头和网络摄像头的视频图像进行智能算法处理。一旦有违规事件发生，系统自动产生警报，从而为用户提供快速、准确和智能的视频监控服务。Abstract： An intelligent surveillance distributed system based on TMS320DM642 is introduced in this project.
