摘　　要：本文对影响交流输电系统输送能力与输送距离的几个主要因素进行了分析，包括同步运行的稳定性，电压和无功控制，串联电容补偿和并联电抗补偿等，并提出了交流输电系统的短路比概念，比较确切地刻划了两瑞交流系统对交流输电系统运行特性的影响。在此基础上，导出了一组交流输电系统输送能力与输送距离的关系曲线，可供电力规划和设计部门参考。Several main factors influencing thetransrnission capability of EHV/UHV AC lines havebeen discussed,including the synchronous stability,voltage and reactive power control,series compensa-tiOn and shunt compensation. The short circuit ratiofor AC transmission system is proposed in this paper,which accurately describe the influence of the two endsystems upon the transmission capability. From theabove analysis,a set of curves reflecting the relation-ship between the transmission capability and the trans-mission distance has been developed, which can beused in electric power system planning and design.
