摘要

本文介绍了用动态相量分析高压直流输电系统终端模块多电平变换器(MMC)小信号稳定性的方法。与基于D-Q变换的模型不同，动态相量模型可以在线性化后进行特征分析，因为它产生时不变模型。动态相量模型还包括基于D-Q变量的MMC控制系统。通过时域仿真对该模型进行了验证，结果表明该模型能够预测不稳定情况下的临界增益。

Dynamic phasor modeling of Modular Multi-level Converters

This paper presents the application of dynamic phasors to analyse small signal stability of a Modular Multilevel Converter (MMC) which can be used as a terminal of HVDC transmission system. Unlike a model based on the D-Q transformation, a dynamic phasor model is amenable for eigen-analysis after linearization, as it yields a time invariant model. The dynamic phasor model also includes the control system of the MMC which is based on D-Q variables. Time domain simulation is carried out to validate the model, and it is shown that the model can predict critical gains for instability.
