针对电流控制方法在静止无功发生器SVG无功补偿上的缺陷，提出了一种先进的电压定向控制算法(VOC)。首先介绍了 VOC 的基本原理，然后详细论述了电压定向控制的拓扑结构及无功电流与有功电流解藕过程，最后在MATLAB/Simulink的环境下进行了系统建模和仿真。仿真结果表明，运行基于电压定向控制方法的SVG装置，系统将得到良好的动态特性，功率因数大大提高，弥补了传统电流控制的缺点，对于SVG的无功补偿效果提高具有重要的现实意义。

In view of the current control method on static reactive power generator SVG reactive compensation defects, put forward a kind of advanced methods of voltage oriented control (VOC). This paper firstly analyzes the principle of work of static var generator SVG voltage type main electric circuit, and then introduces the structure of the control system, and this essay discusses the voltage directional control topology and the process of reactive current and active current decoupling, at last a system simulation is carried out in the MATLAB/Simulink environment. Through the experiment waveform, it is known that the voltage oriented control method was applied to SVG, the system can get good dynamic and static characteristics, the effect of reactive power compensation is very good.
