| 摘 要： | 为了使电子电力变压器具备跨越瞬时电压中断的能力,提高供电可靠性,对应用于电子电力变压器的储能系统进行了研究。所提储能系统由一个超级电容储能单元和一个双向直流变换器组成,储能单元通过直流变换器和电子电力变压器相连。为了提高储能系统中直流变换器的控制性能,提出了一种基于线性二次型调节的优化控制策略。最后,所提系统在基于DSPTMS320F2812所构建的实验系统下进行了实验验证。实验结果证明了基于超级电容储能的电子电力变压器具备跨越瞬时电压中断的能力和所提优化控制策略的有效性。

| Abstract: | In order to make EPT provide added ability to ride voltage momentary interruptions, the energy storage system of EPT is studied in this paper. The proposed energy storage system consists of an ultracapacitors bank and a bidirectional DC-DC converter, and the ultracapacitors bank is connected to the dc link in EPT through the dc-dc converter. In order to improve control performance of the bidirectional DC-DC converter, an optimal control scheme based on the linear quadratic regulator (LQR) is also presented ... |
