The control strategy of static vat generator （SVG） is analyzed. The software and hardware implementation process is designed based on chip TMS320LF2407A digital signal processing （DSP）, which includes hardware circuit diagram and software flowchart of each function. By Matlab/Simulink, the simulation result shows that, the system adopts direct current control strategy based on instantaneous reactive power can realize compensation effectively.%分析了静止无功发生器（SVG）的控制策略，设计了基于TMS320LF2407A的数字信号处理芯片（DSP）的软硬件实现过程，包括各个功能的硬件电路图和软件流程图。通过Matlab／Simu-link仿真结果表明，该系统所采用的基于瞬时无功功率理论的直接电流控制策略，能够很好地实现补偿效果。
