摘　　要：为解决华东电网500kV线路输送能力受制于线路热稳定水平的问题,从理论上分析了通过实时监测导线运行环境来提高导线输送容量的方法的可行性,并重点介绍了根据实测运行中500kV线路风速、环温、日照强度等参数,计算导线载流量的结果和试验室线路温升的模拟试验结果,结果表明通过运用实测线路环境参数实时确定导线输送限额是可行的,一般情况下可提高线路输送容量10%～30%.The transmitting capacity of 500kV transmissionline in East China power grid is restricted by thermalequilibrium. To enlarge the transmitting capacity, the authorstheoretically analyze the feasibility of increasing conductingwire’s transmitting capacity by means of real-time monitoringthe operation environment of conductors, and emphaticallypresent the calculated conductor’s current capacity according toon-site measured parameters such as wind speed, ambienttemperature, sunshine intensity, etc., and the sim...
