中文摘要

基于电力电子的三级智能变压器(ST)在启动阶段若控制协调不当,易受浪涌电流和过电压影响而损坏。本文针对具有分布式直流链路的模块化架构,设计了一种关键的软启动程序,以确保系统在启动过程中的安全与稳定。

English Abstract

Power electronics based three-stage smart transformers (STs) can be seriously damaged by inrush currents and overvoltages during the start-up phase if the control of the stages is not correctly coordinated. Hence, it is crucial to design properly the start-up procedure, especially in case of modular architectures with distributed dc-links. The design of the start-up procedure depends on the ST pow...

该研究涉及的级联H桥(CHB)与双有源桥(DAB)拓扑是阳光电源大功率储能系统(如PowerTitan系列)及中压并网变流器的核心技术基础。分布式直流链路的软启动策略对于提升储能变流器(PCS)在复杂电网环境下的可靠性至关重要。建议研发团队参考该文的启动协调控制逻辑,优化PowerTitan系列在黑启动及并网瞬间的冲击电流抑制能力,从而降低功率器件的应力,提升系统全生命周期的运行稳定性。
