摘要
本文详细介绍了100kVA三相四线制系统用增强型SVG装置的研制和实验运行情况。文中首先简要分析了该装置的工作原理,然后介绍了装置所采用的四臂对形式的主电路拓扑结构和基于双DSP的数模混合控制的控制策略,最后给出了多种补偿功能实验和现场运行的结果。结果表明,本文所提出的装置采用TTA(基于时域变换)算法,不但具有良好的谐波补偿能力,并且还能补偿无功和抑制不平衡电流和中线电流。该装置运行稳定,补偿方式灵活,具有很高的现实意义。
A device of 100kVA enhanced SVG （Static Var Generator） with three-phase four-wire power system is introduced in this paper, which is based on dual DSP control scheme. First, the basic operation principle of device is presented briefly. Then it is proposed that the main circuit is four-leg topology configuration. The dual DSP circuit is adopted to realize the digital-analog hybrid control scheme. At last, some field running and multi-function experimental results are obtained. The results show that the device based on TTA （Time-domain based Transform Algorithm） has the perfect performance in that it not only decreases largely THD but also compensates effectively the reactive and imbalance current. The device runs steadily and has the flexible compensation ability, which is worth developing in practice.
