Abstract

The study on the simulation model of the metal oxide arrester (MOA) is of great significance to its production test and application. Simulation method is usually applied to MOA simulation test for some small and medium-sized enterprises with limited test conditions. The situation that there are a great wide variety of MOA models makes it more significant to study their applicability. The MOA simulation model research status was introduced in this paper, and three models, including IEEE model, Pinceti model and MWR model, were carried out by the Alternative Transient Program-Electromagnetic Transient Program (ATP-EMTP), where the Heidler current source and the RLC discharge circuit were used to produce different impulse currents, including 8/20μs, 30/80μs and steep current with front time about 1μs. Besides, the lightning impulse simulation of the whole arresters was experimentally researched under the nominal current. Then simulation results and experimental results were compared and analyzed according to the relative error of residual voltage and energy absorption. It is shown that the simulation waveform of the RLC discharge circuit is similar to the test waveform, which can effectively improve the problem of large relative error of the absorption energy, and the residual voltage simulation results of the three models are all good under 8/20μs and 30/80μs current. The IEEE model has shown good agreement in terms of the results of MOVs under steep current and the whole arresters under the nominal current. The difference between the two kinds of circuit design was analyzed, which can provide a reference for solving the problems in the current research, and improve work efficiency for testing institution.
