中文摘要

随着更多电力飞机(MEA)中电机和电力电子变换器集成度提高,恒功率负载(CPL)占比持续上升,对机载电力系统的稳定性构成挑战。本文针对高压直流供电系统,提出了一种有源阻尼控制策略,以有效抑制系统振荡并提升稳定性。

English Abstract

With the increasing integration of motors and power electronic converters into the electric power system (EPS) of the more electric aircraft (MEA), the proportion of constant power load (CPL) continues to rise. This poses significant challenges to the stability of onboard EPS. In this article, an active damping control strategy is proposed for the high-voltage dc power supply system utilizing a wo...

该研究探讨的直流系统稳定性与恒功率负载(CPL)控制,与阳光电源的储能系统(PowerTitan/PowerStack)及组串式逆变器在弱电网环境下的运行逻辑有共通之处。虽然应用场景为航空领域,但其提出的有源阻尼控制策略对于提升阳光电源产品在复杂电网环境下的阻抗匹配能力、抑制直流侧电压振荡具有重要的参考价值。建议研发团队关注该策略在构网型(GFM)储能变流器中的应用,以增强系统在弱电网或高比例电力电子负载下的动态稳定性。
