Abstract

In a low voltage distribution network, wisely applied local reactive power generation can improve voltage profiles and reduce loses related with the energy transmission. This paper deals with the laboratory realization of a Static VAr compensator (STATCOM) suitable for adjustable local reactive power generation. In the case study, the basic design of a 10 kVA STATCOM is presented. The paper contains description of the discussed system, design of the LCL output filter, and determination of gains for the Voltage oriented control with PI controllers (VOC-PI). The comparison of measured and calculated responses shows a good agreement. The results presented in the paper show acceptable dynamic responses satisfactory power efficiency of the laboratory STATCOM realization.

静态无功补偿器的实验室实现
在低压配电网中,合理地应用局部无功发电可以改善电压分布,减少与能量传输有关的损失。本文研究了适用于可调局部无功发电的静态无功补偿器(STATCOM)的实验室实现。在实例研究中,介绍了一个10kva的STATCOM的基本设计。本文介绍了所讨论的系统,LCL输出滤波器的设计,以及用PI控制器(VOC-PI)进行电压定向控制的增益确定。实测响应与计算响应的比较表明,两者吻合较好。实验结果表明,实验室实现的STATCOM具有良好的动态响应能力和较好的功率效率。
