中文摘要

直流三级发电机(TSG)是航空高压直流电源系统的核心。随着非线性负载增加,系统稳定性面临挑战。本文提出了一种直流三级发电机的模块化建模方法,基于双端口网络模型建立了整体系统模型,用于分析其阻抗特性及稳定性。

English Abstract

DC three-stage generator (TSG) has been widely adopted as the main power source in aviation high-voltage dc power systems. With the increase in nonlinear loads, it poses challenges to the stability of the DC-TSG. Thus, the modeling of the system is important. In this article, a modular modeling method for the DC-TSG is proposed, and the overall model is established based on the two-port model of i...
