随着电力工业的发展，电力系统的规模越来越大，在这种情况下，许多大型
的电力科研实验很难进行，尤其是电力系统中对设备和人员等危害最大的事故故
障，尤其是短路故障，而在分析解决事故故障时要不断的实验，在现实设备中很
难实现，一是实际的条件难以满足；二是从系统的安全角度来讲也是不允许进行
实验的。考虑这两种情况，寻求一种最接近于电力系统实际运行状况的数字仿真
工具十分重要，而 MATLAB软件中的 SIMULINK是用来对动态系统进行建模、仿真
和分析的集成开发环境，是结合了框图界面和交互仿真能力的非线性动态系统仿
真工具，为解决具体的工程问题提供了更为快速、准确和简洁的途径。
Along with the development of the electric power industry, the scale
of the power system is more and more big, in this case, many large power
research is difficult to, especially in the power system, equipment and
personnel to the harm such as the biggest accident, especially fault fault
location, and on the analysis of the accident to solve the fault of the
experiment, in the reality constantly in equipment, it is difficult to
accomplish a is practical conditions to meet; The security of the system
from the perspective is not allowed in the experiment. Consider the two
kinds of circumstances, for one of the most close to power system actual
the operation condition of digital simulation tool is very important, and
MATLAB software SIMULINK is used for the dynamic system modeling,
simulation and analysis of the integrated development environment, is
combined with the block diagram interface and interactive simulation of
nonlinear dynamic system ability of simulation tools, to solve the
specific engineering problem, provides a more rapid, accurate and simple
way.
