中文摘要

模块化多电平变换器(MMC)由数百至数千个半桥子模块组成,其庞大的开关数量和节点数给电磁暂态计算带来巨大挑战,尤其在实时仿真领域。本文探讨了利用CPU与FPGA协同处理实现MMC实时仿真的可行性,旨在解决复杂电力电子系统的计算瓶颈问题。

English Abstract

Modular multilevel converter (MMC) structures are composed of several hundreds to thousands of half-bridge converters. Such large numbers of power switches and electrical nodes introduce important numerical challenges for the computation of electromagnetic transients. The problem becomes particularly more complex for the real-time simulations. This paper presents a feasibility study on the real-ti...
