| 为满足未来配电网智能化的发展需求，实现配电环网潮流柔性调控，提出了一种能够满足城市配电环网潮流柔性调控的直接式AC/AC型混合配电变压器(AC/AC-HDT)。提出了AC/AC-HDT的拓扑结构并对其运行原理、优势进行分析与对比。基于此，结合现有配电环网的主要闭环方式，提出了含AC/AC-HDT的城市配电环网组网方案。基于配电环网潮流调控基本原理，给出了AC/AC-HDT在城市配电环网潮流调控中的策略流程。通过实验室AC/AC-HDT原理样机的搭建以及含AC/AC-HDT的双电源配电环网潮流调控效果的仿真分析，验证了所提直接式AC/AC-HDT拓扑的合理性以及其在配电环网潮流柔性调控中应用的可行性。 |

| Abstract: |
| In order to meet the demand of intelligent development of distribution network in the future and realize the power flow flexible regulation of distribution loop network, a direct AC/AC-HDT(AC/AC based Hybrid Distribution Transformer) is proposed, which can meet the demand of flexible regulation of power flow in urban distribution loop network. The topological structure of HDT is proposed, its operation principle and advantages are analyzed and compared. On this basis, combined with the main closed-loop mode of existing distribution loop network, the network scheme of urban distribution loop network with AC/AC-HDT is proposed. Then, based on the basic principle of power flow regulation of distribution loop network, the strategy of power flow regulation of urban distribution loop network is given. Through the construction of the laboratory prototype and the simulation analysis of the power flow regulation in dual power distribution loop network with AC/AC-HDT, the rationality of the proposed direct AC/AC-HDT topology and the feasi-bility of its application in power flow flexible regulation of distribution loop network are verified. |
