中文摘要

针对电力电子系统高开关频率与大规模化带来的实时仿真挑战,本文提出了一种事件驱动硬件在环(ED-HIL)仿真框架。该框架摆脱了对固定小步长仿真周期的依赖,通过精准定位开关事件,有效提升了计算效率,并解决了传统电路分割方法中常见的仿真失真问题。

English Abstract

The trend toward higher switching frequency and larger scale of power electronic systems poses challenges for real-time simulation. This article presents an event-driven hardware-in-the-loop (ED-HIL) simulation framework that does not rely on the small fixed simulation step-size related to the switching frequency. ED-HIL framework can improve the calculation efficiency by positioning switch events...
