Metal oxide arrester(MOA)is a important device for over-voltage protection in high-voltage and extra-high-voltage power system. In this paper, a system model based on the Power System Blockset(PSB)of MATLAB for EHV transmission line with series compensation is proposed, and the over-voltage protection capability of MOA is simulated. It provides some reference for the study and selection of MOA. also based on PSB model and using simulink mathematical module, the simulation of accurate fault of high voltage power transmission lines is implemented. Simulation results show that the built model is simple and easy to use, the accuracy of simulation results by use of Matlab are satisfactory and can meet the requirement of engineering. Analysis of large scale circuit often makes use of the node method. Matlab has large ability of matrix arithmetic and was widely used in the electronic technology. The article discusses the method of modeling in analysis of large scale circuit with Matlab. The article makes a lot of program to analyze the voltage and the current of the circuit, and gives an example to account for the method which analyzes large scale circuit with Matlab. The article also discusses general calculating method of negative sequence current based on matalb. the article gives models of them and emulates them using MATLAB language. On the basis of kinds of the circuitry malfunetions analysis under diferent conditions, various algorithms are researched ,Finally, achieving the main algorithm of filter and protection on distance protection, analyzing and comparing the accuracy and rapidity of the algorithm.
