使用MATLAB R2009a作为最基础平台,依靠SimPowerSyetem建立起了我们常见的双机系统模型,通过设置该系统接地故障以及故障点的分布来得到仿真波形图

摘要现在的电力产业发展愈发迅猛,系统线路的规格越来越繁杂和多变,与之相对应的是其带来的多种多样的故障,这样一来就会使电厂内的元器件以及各种配套设备受到很大的影响,而且有可能使得事故扩大从而变的不可控,我们在参考了安全性和实用性以后,觉得直接在大电网中实验是很不科学的。所以应该参考电路电网模型使用仿真分析来辅助,本文使用MATLAB里的Simulink建立起了一个双机系统的仿真模型,基本上可以解决线路发生故障时遇到的各种各样的情形。37918
本文使用MATLAB R2009a作为最基础平台,依靠SimPowerSyetem建立起了我们常见的双机系统模型,通过设置该系统接地故障以及故障点的分布来得到仿真波形图,然后对比得出结论。
本文做的主要工作有:
   (1)MATLAB/Simulink中进行系统建模仿真
   (2)在系统线路的电气中点安置短路故障点,我们在模拟安置单相接地短路故障,两相接地短路故障以及三相接地短路故障的时候,FACTS对这个电力线路稳定性的影响。得到与之相对应的仿真波形图,然后对比它们得出结论。
最后通过实际操作得出的波形图,我们知道了解了FACTS装置对电力线路稳定性的影响。

Abstract
Now the more rapid development of power industry, more and more complex system specifications and lines varied, corresponding to that which brings a wide range of fault, so that will make the components within the plant as well as the kind of equipment was seriously affected, and is likely to make the accident and thus becomes uncontrollable, we have reference to the security and usability in the future, I feel directly in a large grid is very scientific experiment. So it should be a reference circuit Power model uses simulation analysis to assist, as used herein in the MATLAB Simulink simulation model established a dual system, basically you can solve a wide variety of situations encountered in the line fails. 源-自*六'维:论.文]网[www.lwfree.cn
This article uses MATLAB R2009a as the most basic platform, relying SimPowerSyetem established our common dual-system model, by setting a ground fault and the fault of the distribution system to obtain the simulation waveform, and then compare concludes.
In this paper, the main work done:
    (1) MATLAB / Simulink modeling and simulation of the system
(2) in the electrical system line midpoint resettlement short circuit fault, we phase short-circuit fault simulation placed in a single, two-phase and three-phase short-circuit fault when a short to ground fault, the impact of the power lines FACTS Stability . Correspondingly get simulation waveform, and then compare them to conclude.
Finally, the actual operation resulting waveform, we know understand the impact of FACTS devices on the power line stability.
