语言:

中文摘要

电力电子变换器的电磁暂态(EMT)仿真因需极小步长来处理开关动作,导致计算负担沉重。为加速仿真,本文将原用于实时仿真的时间平均法(TAM)进行推广,使其适用于离线仿真,在保持谐波模拟精度的同时显著降低了计算开销。

English Abstract

The electromagnetic transient (EMT) simulation of a power system involving power-electronics converters requires a fairly small time-step size to consider switching of the converters, thus leading to a heavy computational burden. To accelerate such simulations, this article generalizes the time average method (TAM), originally developed for real-time simulations, so that it becomes suitable to off...
