Fault Simulation Study for High Voltage Line Based on ATP-EMTP and MATLAB

摘要: 随着社会对能源需求的增长和发电技术的进步，电力网络拓扑系统越来越复杂，运行难度也随之增加，而且发生的故障也难以用传统的分析方法进行预测，从而使得电力系统分析和仿真技术成为电力系统规划、设计、运行、分析及改造等过程中不可缺少的工具和手段。本文对电力系统中发生的几种短路故障进行了分析，并在此基础上创建了基于ATP-EMTP仿真软件的故障仿真模型，然后分析不同故障下的仿真波形，从而为进一步分析提供依据。通过研究输电线路各类运行故障的特点和机理，提出针对性的防治措施，对于增强电网抵御自然灾害的能力和提高安全运行水平十分重要。

Abstract: Along with the increase of energy demand and the progress of power generation technology, topological system of power network is more and more complex; the operation difficulty also increases. The fault is difficult to forecast with the traditional analysis methods, then power system analysis and simulation technology become the indispensable tools and instruments in the power system planning, design, operation, analysis and the process of reforming. In this paper, many kinds of short circuit fault in power system are analyzed. The fault simulation model based on the ATPDraw simulation software is created. Then, this paper analyzes the waveform of different fault simulations, studies the characteristics and the mechanism of the transmission lines of various kinds of failures, and puts forward corresponding prevention measures to enhance the ability of withstanding natural disasters in power grid. The prevention measures are very important to improve the level of safe operation.
