摘要：
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.
