针对SVG相关理论的研究，在坐标变换的基础上，对SVG的数学模型进行了构建和分析。研究了静止无功发生器的控制策略，重点对瞬时无功功率的无功电流检测方法进行分析，并对其检测算法进行了改进，以适应电网电压出现三相不对称时的情况。利用Matlab仿真软件，对静止无功发生器的仿真模型进行系统仿真，结果表明基于改进算法的系统模型具有很好的动态无功功率补偿性能。

The essay takes a research on the reactive power and power factor theory and carries on the analysis to the basic principle of SVG, on the basis of coordinate transformation, the mathematical model of SVG is built and analyzed. Studied the static reactive power generator and the control strategy of focusing on the reactive current detection method of instantaneous reactive power is analyzed, and the de-tection algorithm was improved to adapt to the power grid voltage appeared three-phase asymmetry. By u-sing the simulation software of Matlab,etablished the simulation model of static reactive power, the results show that the system model based on the improved algorithm has good dynamic reactive power compensa-tion performance.
