摘要: |
变压器作为电网中保持电压稳定性和改善电网电压质量的一种重要设备,一直是相关领域的研究热点。近年来随着电力电子技术的发展,由于电力电子器件相较于传统机械结构的高度可控性和不产生电弧的特性,变压器逐渐呈现电力电子化的趋势。首先将变压器按电力电子化发展方向的不同分为了两个阶段,并归纳总结了变压器电力电子化进程各个阶段的拓扑结构。在此基础上对每个电力电子化阶段的变压器对有载调压的影响做了详细介绍。最后对不同电力电子化阶段的变压器对电压稳定性的影响做了对比,对变压器的发展趋势和关键问题进行了总结与展望。 |

Abstract: |
The transformer, as an important piece of equipment to maintain voltage stability and improve voltage quality in the power grid, has been a research hotspot in a number of fields. With the development of power electronics technology in recent years, transformers gradually show a trend in power electronics because of the high controllability of power electronics devices compared with traditional mechanical structures and their characteristics of no arcing. This paper divides the development direction of power electronic transformer into two stages, and summarizes the topology of the power transformer electronic process stages. On this basis, the impact of each power transformer at an electronic stage on on-load voltage regulating is introduced in detail. Finally, the influences of power transformers at different electronic stages on voltage stability are contrasted, and the development trend and the key problems of the transformer are summarized and prospected.
