基于主动探测技术的输电线路驱鸟策略研究

为解决鸟害引起的输配电线路故障,通过总结鸟害故障机理,分析鸟害事故较严重的华北地区鸟害的时间规律,提出了基于光电探测技术、激光立体扫描和能源优化设计的驱鸟策略。研究表明,鸟害故障一般发生在春秋两季,且06:00~08:00时间段故障率较高;光电探测技术可探测与探测平面成60°范围内的飞鸟;激光器可实现上下左右10°范围内立体式驱鸟,覆盖范围广;驱鸟策略采用定扫模式和巡航模式,系统综合功耗优化至38AH,鸟害故障率降低了60%。研究结果为输配电线路鸟害故障治理提供了参考。

Research on Anti-bird Strategy for Transmission Line Based on Active Detection Technology

In order to solve bird-caused damages of transmission and distribution lines, the time rule of serious damages in north China was analyzed by summarizing the mechanism of bird-caused damages. This paper put forward the strategy of bird repellent based on photoelectric detection technology, laser stereoscopic scanning and energy optimization design. The results show that the bird-caused damages occurred in spring and autumn, besides, the failure rate is high at between 6:00 am and 8:00 am; Photoelectric detection technology can achieve the detection of birds within the range of 60°; Laser could achieve three-dimensional anti-bird, which was covering a wide range of 10°; Anti-bird strategy adopted the constant sweep mode and cruise mode, the system integrated power consumption is optimized to 38 AH, and the bird-caused damages rate is reduced by 60%. The results can provide the references for the prevention and control of bird-caused damages.
