[Abstract]:Real-time reactive power compensation is an effective method to improve power quality and can improve the stability of transmission system. At present, the most ideal scheme is to adopt SVG: static VAR Generator, which is the representative of the latest technology in the field of reactive power compensation. More and more applications in various industries, universities and research institutes have also invested a lot of resources for research. Based on this background, a three-level voltage source SVG platform is designed. In this paper, the current research status of SVG at home and abroad is reviewed, and a three-level neutral point clamping SVG device is proposed. Then the simulation model is built in Simulink, and its working principle, topology and control strategy are analyzed and studied. Finally, the main circuit components are selected, the control software program is written, the control board based on DSP, the auxiliary DSP board, the AC sampling board, the relay board and the PWM and fault driven switch board are designed. Combining with "T" IGBT module, the experimental platform of 13kVar SVG is built successfully. Through the combination of simulation and experiment, the correctness of the control strategy and the reliability of the experimental platform are verified. It has been successfully applied to the experimental system of "Electric vehicle grid-connected scheduling" in the laboratory.
