摘　　要：无间隙金属氧化物避雷器(以下简称MOA)是电力系统过电压防护不可或缺的保护设备,是绝缘配合的基础。随着计算机功能的不断提升,电磁暂态仿真计算已成为电力系统选择、配置MOA及绝缘配合等的主要手段,MOA仿真模型的准确性直接影响着工程的可行性和造价。本研究针对MOA仿真计算模型适应性展开研究,通过实验和仿真对比分析了目前国内外认可使用的四种MOA模型,从不同暂态波作用下的残压特性、吸收能量和波形方面评价了各自的准确性和适应性。Metal Oxide Surge Arrester(referred to as MOA) is an indispensable protection equipment for power system overvoltage protection,and it is the basis of insulation coordination.With the continuous improvement of computer functions,electromagnetic transient simulation calculation has become the main means of power system selection,MOA configuration and insulation coordination.The accuracy of the MOA simulation model directly affects the feasibility and cost of engineering.The adaptability of MOA simulation models is carried out.Through experiments and simulation,four kinds of MOA models currently approved at home and abroad are compared and analyzed.And their accuracy and adaptability are evaluated from the residual voltage characteristics,absorbed energy and waveform under different transient waves.
