论文摘要
在美国，森林大火的数量和强度一直在稳步增加，并造成了巨大的经济和生态破坏。高架的传输和分配线通常在火灾附近脱离了预先连接，这种做法会导致高昂的社会成本。相量测量单元（PMU）的部署及其同步的实时测量电压和电流的能力激发了此处提出的方法，即在点火或火的点火或方法下，跨越时间连接的方法。 PMU可以通过线阻力的变化来检测由火灾引起的环境温度变化。 MATLAB Simulink中使用了火座椅附近的环境温度模型和IEEE 738动态线等级标准的动态热交换模型，以评估所提出的控制方法的性能。广泛的测试表明，在各种条件下，提出的技术可以检测到森林大火接近高架线，同时几乎完全避免了任何错误的警报。
The number and intensity of forest fires in the United States have been steadily increasing and causing massive economic and ecological damage. Overhead transmission and distribution lines are typically disconnected preemptively near fires, a practice that causes high social cost. Deployment of Phasor Measurement Units (PMUs) and their ability for synchronized real-time measurement of voltage and current inspire the here proposed method for the just-in-time disconnection of overhead lines at the ignition or approach of fires. PMUs can detect ambient temperature changes caused by fires through the change of line resistance. An ambient temperature model at the vicinity of a fire seat and the dynamic heat exchange model of the IEEE 738 dynamic line rating standard for bare overhead conductors are used in MATLAB Simulink to assess the performance of the proposed control method. Extensive testing shows that, under various conditions, the proposed technique can detect a forest fire approaching an overhead line, while avoiding, almost completely, any false alarms.
