1000 kV交流特高压输电线路运行特性分析

依据我国及世界各国特高压输电研究成果以及前苏联和日本特高压输电线路运行经验,并结合我国的特高压输电示范工程路径的特点和途径地区已有各电压等级输电线路的运行经验,对晋东南—南阳—荆门1000kV交流特高压输电示范工程建成投运后的运行特性及其对自然环境的影响进行了分析,重点分析了特高压输电线路的雷电、防污闪、冰风、防鸟害等特性,对建成后特高压输电线路的电磁环境进行了评估,并对特高压输电线路的运行指标作出了预测。

Analysis on Operating Characteristic for 1000 kV AC UHV Transmission Line

Based on the research results of UHV transmission line home and abroad as well as the operating experiences of UHV transmission line in Russia and Japan,and considering the features of UHV demonstration project in China and operating experiences of UHV transmission lines in different voltage classes which locate in the path where the UHV demonstration project passes through,the operating characteristics of the 1000 kV AC UHV demonstration project from southeastern Shanxi province via Nanyang in Henan province to Jingmen in Hubei province after its complete and putting into operation.Especially,the prevention characteristics for disaster,such as lightning stroke,flashover caused by pollution and the damage caused by icing,wind and bird,are emphatically analyzed.The electromagnetic environment of this project after its complete is evaluated and its performance indices are also forecasted.
