摘要
2008年国网电力科学研究院开始进行特高压单回紧凑型输电关键技术的研究,在总结已取得的特高压输电技术科研成果的基础上,充分利用特高压交流试验基地(武汉)的良好科研条件,根据特高压紧凑型输电线路的特点,开展了多项有针对性的关键技术研究。为此,介绍了包括特高压紧凑型线路电磁环境及导线布置优化、外绝缘特性研究、过电压及绝缘配合、带电作业、金具研制及防舞动措施研究等方面所取得的一系列重要参数和研究结论。并且明确了特高压紧凑型输电关键技术的下一步研究工作重点,指出了需要在导线舞动相间安全间隙控制、进一步减小电晕噪声、带电作业以及系统稳定等方面继续开展全面深入的研究,为我国今后的特高压紧凑型输电工程做好全面的技术储备。
The study on the key technologies of ultra high voltage （ UHV） compact transmission line has been started by State Grid Electric Power Research Institute （SGEPRI） scince 2008. By summarizing the previous work on key technologies of UHV transmission line and UHV AC Pilot Project and by fully utilizing the advanced test equipment in UHV AC test base in Wuhan, SGEPRI has researched a number of professional fields, such as electromagnetic environment and layout optimization of conductors, external insulation characteristic, overvoltage and insulation co- ordination, live working, fitting design and measures against galloping of transmission line. And some important pa- rameters and research conclusions have been achieved. According to the research conclusions, we presented the fo- cuses of further work, such as the control of security clearance between phases, reducing further the corona noise, live working, system stability and so on, and the UHV transmission project. technieal reserves for the subsequent compact construction of
