摘　　要：针对内部过电压为超高压电网绝缘水平的决定因素,应用电磁暂态分析程序ATP-EMTP仿真计算软件,分析了不同故障状态下及断路器操作过程中可能出现的过电压及其影响因素。实例仿真计算结果验证了理论分析的正确性,为确保输电网络稳定性、提高输电能力、采用实用化新技术和措施提供了依据。Internal overvoltage is the most important factor of EHV power grid insulation corrdination . Researches on the most serious over-voltage emerged during circuit breaker operations of different fault conditions and its influencing factors have been done by using the electromagnetic transient program ATP-EMTP. Simulation results of actual projects have verified the correctness of the theoretical analysis, and it provides theoretical basis to ensure the stability of transmission network and to increase the transmission capacity, also to the use of new technologies and practical measures.
