摘　　要：为解决华东电网500kV线路的输电能力瓶颈矛盾,开展了提高现行线路载流量的研究。介绍了根据实测导线温度、电流、环境温度、风速、日照强度等参数对计算模型进行修正后的动态输送限额的计算方法,对提高现有线路的输送容量的可行性进行了分析讨论。To solve the bottleneck of transmission capacity of 500 kV power lines in East China Power Grid, the study of increasing the carrying capacity of current transmission lines was conducted. The method that uses the measured conductor temperature, current, environment temperature, wind speed and solar radiation to modify the calculation models and to calculate the dynamic transmission limitation for capacity increase is introduced, and the feasibility of increasing the current line carrying capacity is analyzed.
