| 摘要: |
| 对电磁暂态分析程序PSCAD/EMTDC与数学模型软件包Matlab之间的接口进行了研究。充分利用了PSCAD/EMTDC与Matlab 2款软件的优点,用PSCAD建立接口模型,启动Matlab数据引擎调用M文件,实现接口模型的参数设置。运用此接口,程序只需运行一次即可获取多组不同工况下的数据。同时分析一个输电线路实例,将接口程序产生的数据进行分段处理,将它作为BP神经网络的输入,进而区分开关操作和单相接地故障。仿真结果表明:接口软件的运用使得大量数据的获取变得更加容易。 |

| Abstract: |
| The interface between PSCAD/EMTDC and Matlab is researched.To make the best use of the electromagnetic transient analysis program PSCAD/EMTDC and the math model software package Matlab,the interface model is built using PSCAD and its parameters are set by calling the M file using the data engine of Matlab.Massive data under different conditions could be accessed via this interface once it runs.An application example of power transmission line is analyzed.Data got via the interface are processed in segments and sent to BP neural network to detect single-phase grounding fault from switch operations.Simulation results point out that this interface software facilitates the acquisition of massive data. |
