针对传统的间接电流控制方法在静止无功发生器(SVG)上应用的缺陷,提出了一种新的直接电流控制方法。在分析SVG的系统结构和工作原理的基础上,详细介绍了直接电流控制的基本原理及其控制结构,并设计了相应的SVG电路模型。结合某煤矿井下的负载情况,对基于直接电流控制的静止无功发生器进行了仿真实验。仿真结果表明,该系统具有良好的补偿效果,可有效地弥补间接控制在动态响应和稳定性的不足。

For the shortcomings of the traditional indirect current control methods applied in static vat generator （ SVG）, proposes a new direct current control method. Based on the analysis of SVG system structure and working principle, detail introduces the basic principles and control structure of the direct current control, and designs the relevant SVG circuit model. Combined with the loading situation of a certain coal mine, making the simulation test of static var generator based on direct current control. The simulation results show that the system receives a good compensation effect, effectively compensates the shortcomings in the dynamic response and stability of indirect control.
