摘要

为解决配电网络中的电压波动问题，本文提出了一种基于直接交流/交流转换器的 SS 补偿 HDT 拓扑，可对电源一次侧进行电压补偿。本文详细介绍了单相 SS 补偿 HDT 拓扑，并选择了双极补偿直接交流/交流转换器。然后，利用状态空间平均法和松弛双端口网络理论构建了 HDT 模型。最后，建立了一个仿真平台来验证和分析 HDT 的电压补偿能力。结果证实，与 LS 补偿 HDT 相比，SS 补偿 HDT 的电压调节范围更稳定，更适合电压下陷条件。

Source-side compensated hybrid distribution transformer based on direct AC/AC converter

To address the voltage fluctuation issue in distribution network, this paper proposes a SS compensated HDT topology based on direct AC/AC converter, which allows voltage compensation on the primary side of the power source. The paper provides a detailed description of single-phase SS compensated HDT topology and selects a bipolar compensation direct AC/AC converter. The model of HDT is then constructed using state-space averaging method and relaxed two-port network theory. Finally, a simulation platform is established to verify and analyze the voltage compensation capability of HDT. The results confirm that SS compensated HDT offers a more stable voltage regulation range compared to LS compensated HDT and is better suited for voltage sag conditions.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
