摘要
近年多个特高压换流站因飞鸟活动导致交流滤波器频繁跳闸,这已经成为交流滤波器跳闸的首要因素。鸟害不但影响交流滤波器设备的安全稳定,严重时会造成直流系统功率回降,甚至导致直流闭锁。本文通过实际案例,从鸟害引起的后果、电容器塔结构、电容器塔绝缘措施、各种驱鸟装置现场应用情况等多方面,全面深入分析总结,以期对特高压换流站电容器等设备防鸟害提供具有实际意义的、可操作性的参考意见。
In recent years,frequent tripping of AC filter has happened at several UHV converter stationsdue to the activity of birds and this has become into the primary factor of AC filter tripping. The bird dam-age can not only affect the safety and stability of AC filter equipment,but also cause DC system power lossin severe cases and even lead to DC system blocking. In this paper,the actual example is taken to analyzeand summarize deeply from such aspects as the consequence of bird damage,structures of different capaci-tor towers,the insulation measures of capacitor towers as well as applications of various anti-bird devices soto provide actual and operational reference for anti-bird of UHVDC converter station capacitors.
