description: The topic of the work is parameter estimation for an electric arc model for reproducing arc overvoltages. The purpose of the work is to develop a model of an electric arc of industrial frequency in the MATLAB / Simulink environment based on known equations and carry out verification. The range of software capabilities was explored. To achieve the goal, the type of equation was chosen; the Schwartz equation is used to implement the model. Created a block diagram in MATLAB / Simulink with the implementation of the network equivalent circuit. The parameters were selected to agree with the literature data. The line inductance is calculated based on the network parameters. The reference current-voltage characteristic of the electric arc and the dependence of current and voltage on time were obtained for the parameters Î±=0,35; Î²=0,5; Ï_0=300 us; P_0=0,7 MW. The model was verified on the basis of a test problem of a short circuit in a 35 kV network. The oscillograms of the model showed an overvoltage ratio of about 2, which is consistent with the data from the literature. The results obtained when working with the model showed the correctness of its work to complete the task, as well as suitability for performing a short circuit test in the network.
