| 摘要: |
| 利用ATP电磁暂态仿真计算程序，对影响过电压的各种因素进行了理论分析，并根据变电站的实例和数据参数建立了仿真计算模型，针对影响配电网过电压的几个因素分别进行了仿真。仿真数据表明单相接地过电压受燃弧时刻、电弧电阻、故障距离和系统对地电容的影响各不相同，其中燃弧时刻对过电压的影响最明显，电弧电阻的影响次之，故障距离和系统对地电容对过电压的影响较小。 |

| Abstract: |
| The various factors causing overvoltage are theoretically researched with ATP（Alternative Transient Program） and the simulation model is established according to the data of a real substation. Several factors causing distribution network overvoltage are simulated：arc occurrence instant，arc resistance，fault distance，system-to-ground capacitance. Results show that their influences on single-phase grounding overvoltage are different：the arc occurrence instant has the greatest influence and the arc resistance has less influence， while the fault distance and system-to-ground capacitance have the least influence. |
