500kV汗沽双回紧凑型线路防舞改造与拉线式防舞技术试点应用

Anti-galloping Transformation and Pilot Application of Guyed Anti-galloping Technology of 500 kV Hangu Double-circuit Compact Transmission Line

紧凑型输电线路的舞动事故日益频繁,严重威胁着架空输电线路的运行安全与稳定供电。针对500 kV汗沽双回紧凑型线路的舞动跳闸故障,根据线路现有的相间间隔棒布置方式,采用紧密三角形的配置方式进行防舞动措施优化治理,提高其防舞动效果。同时,将拉线式防舞技术试点应用于该线路,考虑相间间隔棒的布置原则以及拉线防舞装置的安装位置,最终给出了综合防舞布置方案。

The accidents of galloping are increasingly frequent in compact transmission lines, which threaten the safe operation and stable power supply of overhead transmission lines. In this paper, according to the galloping trip of 500 kV Hangu double-circuit compact transmission line, the configuration of close triangle pattern is used to optimize the anti-galloping measures and promote its effect, based on the current layout of inter-phase spacers. Meanwhile, the pilot application of guyed anti-galloping technology is applied to the line. The comprehensive anti-galloping layout is presented eventually, after the consideration of the layout principle of inter-phase spacers and the installation position of the guyed anti-galloping device.
