电网故障条件下集成式混合配电变压器的运行与分层协调控制

Operation and Hierarchical Coordination Control of Integrated Hybrid Distribution Transformer under Grid Fault Conditions

语言:

中文摘要

混合配电变压器(HDT)结合了工频变压器的高效可靠性与固态变压器的功率可控性。本文针对HDT在电网故障下的穿越能力进行研究,提出了一种分层协调控制策略,旨在解决现有研究中缺乏对HDT内部变换器与电网故障响应协调关系的问题,提升系统在复杂电网环境下的运行稳定性。

English Abstract

The hybrid distribution transformer (HDT) achieves a compromise between the low-frequency transformer (LFT) and the solid-state transformer. It combines the LFT's efficiency and reliability with the added advantage of partial power controllability via an integrated converter. However, the existing research on the HDT fault ride-through does not consider the coordination relationship with its own s...
