电力系统输电线路故障测距问题研究MATLAB仿真

Abstract Electricity is indispensable an important part of human production and living. Fault location technology as an important part to ensure the safe operation of the power system stability and security has been focusing in the study of electric power industry. Firstly, this article analyzes the existence of transmission line fault location, significance, development situation and the basic requirements from all aspects. And according to the transmission line distance measurement algorithm by using the basic idea of the existing algorithms are classified, which can be roughly pided into traveling wave method, impedance method, fault analysis and intelligent method, and then the theoretical basis and application condition of various algorithms used by carried on the elaboration and analysis, comparison and discussion, and on this basis, summarized the advantages of the localization algorithm is obtained and the existing problems, and summarizes the positioning range using scope and limitations of the algorithm. Afterwards, focusing on modern traveling wave distance measuring principle, which is detailed introduced some basic concepts of the traveling wave ranging method, analyzes the formation cause of reflection and refraction of traveling wave, weak and deformation characteristics，calculation and wave. Compares the wave and meticulous research, helps us to understand the improvement of the traveling wave ranging method. Through the introduction of modern traveling wave ranging method, and the comparison of several methods for, summed up the disadvantages of the single and double side location， help us to better applied to the actual fault location. Finally, this thesis I selected the end-to-end distance measurement method to simulation using MATLAB simulink.
