基于Matlab工具的电力系统故障分析

Fault Analysis Based on the Matlab Tool for Power System

本文利用MATLAB中的SIMULINK模块建立了电力系统的模型,并在不同的地点设置不同类型的故障,观测故障时采样点的各相波形,以验证Matlab软件分析电力系统故障理论的可行性。以IEEE11节点模型为例,制作了界面友好的图形窗口,选择故障地点以及故障类型,并将故障相的波形显示在图形窗口之上,借以分析实际波形与理论波形的异同,并讨论提出改进措施。

In this paper,using the MATLAB SIMULINK mod- ule in power system model is established, and at dif- ferent locations and different types of fault,fault sampling observation of each phase of the wave- form,to verify the Matlab software system fauh anal- ysis theory. In the IEEEll node model as an exam- ple,making the interface friendly graphical window, select the fault location and fault type ,fault phase and waveform display in the graphics window above,in order to analyze the actual waveform and the theoretical waveform similarities and differ- ences,and discusses the improvement measures were put forward.
