1、基于PSCAD和MATLAB的电力系统电磁暂态仿真研究摘要电磁暂态的研究主要是针对电力系统出现故障时对系统参数进行分析。本文根据电力系统的故障分析理论,运用电磁暂态仿真软件PSCAD/EMTDC和系统仿真软件MATLAB,以双电源供电系统为模型分别对其进行了单相接地、两相相间短路及三相接地故障条件下的电磁暂态仿真分析,通过仿真结果比较,得出两种仿真环境下的仿真波形几乎一致,与故障分析算例基本吻合,这说明这两种仿真环境都适用于电力系统的电磁暂态仿真,但在故障设置方面,PSCAD的设置更为灵活方便。同时,由PSCAD建
2、立一个简单的交直流传输系统为模型,根据PSCAD-MATLAB接口技术原理,实现了接口环境下的电磁暂态仿真研究,这说明了PSCAD-MATLAB接口仿真技术在电磁暂态分析中的有效性。关键字:电磁暂态;PSCAD;MATLAB;接口技术内蒙古科技大学毕业设计说明书(毕业论文)ThesimulationstudyforelectromagnetictransientinpowersystembasedonPSCADandMATLABAbstractElectro-magnetictransientresearchmai
