| 摘 要： | 静止无功发生器(SVG)在高压输电系统中已经得到了成功的应用，但是由于技术、资金等方面的高要求，使得它在低压配电系统中的应用很少。因此，在低压配电系统中采用经济、实用的单桥路SVG装置来补偿系统的无功功率，将SVG的应用拓宽到低压配电领域。详细介绍了单桥路SVG的结构和无功发生原理，建立了相关的控制模型，结合模型推导出动态过程的数学表达式，并对其稳定性进行了讨论。分析了现阶段已完成的设计任务以及达到的效果，提示了装置参数选取时需注意的问题，拟定了未来装置其他部分的设计方案，给出了控制系统的程序流程图。

| Abstract: | SVG had being successfully used in high voltage power transmission system.But,it was seldom used in low voltage distribution system since the high requirement of technology and financing.Using economical and practical singlebridge SVG equipment in low voltage distribution system to compensate reactive power is put forward.The structure and reactive power generation of singlebridge SVG was introduced in details, the control model was established,the mathematical expression of model during the dynamic process was deduced,stability of the system was discussed.The paper also analyzed the finished working and the effect of it,give some advice during the selection of main parameters,and study out the design options in the future.At last,list the program flow chart of the control system. |
