Study on Adaptability of Transient Calculation Model for MOA under Lightning Impluse

Due to the extreme nonlinearity and multivariable influence of the V-A characteristics of MOA, the MOA models are significantly different under different transient conditions. In order to explore the adaptability of the simulation calculation model of MOA under different transient conditions and improve the accuracy of transient overvoltage calculation and analysis, the impulse current test platform is established in this paper for the four simulation models of MOA proposed at home and abroad. the differences between the current waveform, residual voltage and energy absorption characteristics of different simulation models under various shock waves and the experimental values is analysed and verified, and the adaptability of the calculation model under different impulse currents is obtained, which is of great significance for the correct selection of MOA models in the subsequent electromagnetic transient simulation research.
