摘要
针对超高压、特高压输电线路多分裂导线上发生的次档距振荡现象,在750kV输电线路上应用次档距振荡在线监测系统,实时监测次档距振荡并分析其振动规律,提出了导线间隔棒优化布置方案并加以实施。应用结果表明:次档距振荡监测系统及间隔棒优化布置方案解决了导线次档距振荡问题,有效提高了750kV输电线路的安全运行水平。
Aiming at the subspan oscillation phenomenon occuring in multiple split conductor of EHV and UHV transmission lines,applies the subspan oscillation on-line monitoring system realtime monitoring subspan oscillation and analyzing the oscillation law in 750 kV transmission line, puts forward the spacing stick optimum disposal scheme. The application result shows that the subspan oscillation on-line monitoring system and the spacing stick optimum disposal scheme solve the problem of subspan oscillation,effectively elevates the safety operation level of 750 kV transmisson line.
