摘　　要：以Visual C++6.0高级程序设计语言为开发平台,研发出输电线路综合防雷及雷击跳闸风险评估系统,可快速计算出输电线路的耐雷水平与雷击跳闸率,实现差异化的防雷保护计算,并对输电线路的防雷性能进行评估,同时还提供了分析反击耐雷水平的影响因素曲线图,方便用户采取相应防雷措施。通过选取沈阳供电公司的实际线路计算,验证了本系统可运用于实际电力系统的输电线路防雷保护计算。Using the Visual C ＋ ＋6.0 high-level programming language as a development plat- form, the transmission line lightning protection and lightning trip evaluation system is developed, through this system, lightning withstand level and lightning trip rate can be calculated rapidly, differen- tiated lightning protection calculation can be realized, and the lightning performance of transmission line can be evaluated and influence factor graphs of the strike back lightning withstand level is also provied, which help the user to take appropriate measures for lightning protection. An actual transmis- sion line of Shenyang Power Supply Company is selected to be calculated, the result proved that this system can be applied in transmission line lightning protection calculation in actual power system.
