摘要
随着社会的不断发展,电力系统逐渐发展成为一个大规模、时变的复杂系统,因而对电力系统仿真分析软件的要求也不断提高。介绍了电磁暂态分析程序PSCAD/EMTDC与数学模型软件包MATLAB的基本概况及优点,鉴于PSCAD/EMTDC与MATLAB/Simulink的接口能综合两者的优点,详细阐述了两者互联的原理及实现方法。在PSCAD中建立了一个简单的电力系统供电模型,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。通过仿真结果比较,得出2种仿真环境下的仿真波形几乎一致,说明了PSCAD-MATLAB接口仿真技术在电磁暂态分析中的有效性。
With the development of society, the power system gradually developed into a large-scale and time-varying complex grid.The requirement of power system simulation analysis software should has been improved. This paper discusses the basic profile and ad-vantages of the electromagnetic transient analysis program PSCAD/ EMTDC and the math model software package MATLAB. The interace between PSCAD/ EMTDC and MATLAB is able to take full advantage of their merits, thus paper analyzes the principle and the implementation of the interface. Finally, a simple model of the power system is built using PSCAD and it presented the implementation ofthe simulation study for electromagnetic transient with the basis of the principle of PSCAD-MATLAB interface. Simulation result showsthe waveforms under two kinds of simulation environment does almost unanimously which has shown that the effectiveness of PSCAD-MATLAB interface techniques in the study of electromagnetic transients.
