摘　　要：电磁暂态仿真程序EMTP(Elector-Magnetic Transients Program)是电力系统中常用的仿真商业软件,它能有效地对电力系统进行分析和研究。简要介绍了EMTP的特点、功能和应用,并通过实例对10 kV小电流接地系统进行理论分析和建模仿真,仿真结果与实际一致,直观形象地表明了小电流接地系统的特点和故障特征,同时也说明了该方法的有效性和可行性。Advanced digital simulation is one of the most effective ways to analyze and research power system, and EMTP is a prevalent simulation software package of power system. The characteristics, functions and application of ATP-EMTP are briefly described in this paper. Theoretical analysis and emulation through example of a 10kV small current neutral grounding system have been carried out. The simulation results are in agreement with reality, which directly and vividly indicates the characteristics and fault features of tbe small current neutral grounding system and proves the method effective and feasible.
