摘要
本文介绍了电科院编写的《输电线路杆塔统计法绝缘配合计算程序》的主要特点,用该程序对±500kV葛上直流输电线路在工作电压、操作过电压和雷电过电压下的绝缘闪络故障率进行了计算和分析,对今后直流输电线路的建设及现有线路的运行提出了建议。
This paper introduces the main characteristics of a com-puter program, Statistical Insulation Coordination Program of transmission towers developed by EPRI. Taking Gezhouba-Shanghai±500kV HVDC transmission line as an example, the insulation failure rates of the line under operation voltage,switching and lightning overvoltage are calculated and analyzed. Some recommendations for construction of new HVDC lines and operation of existed ones are presented.
