Ice monitoring system of overhead electrical power lines

针对目前国内外覆冰监测的使用状况和存在的问题,按照实际测量的技术要求,对电力线覆冰监测系统进行了研究。通过对耐张塔张力和微气象参数的测量,在运用力学法分析覆冰测量原理的基础上,结合电力线舞动因素,推导出导线覆冰厚度的计算数学模型。依据实际使用的环境特点,给出了基于微功耗单片机MSP430F149电力线覆冰监测系统的设计方案,介绍了系统的部分硬件电路设计和软件流程框图,并讨论了仪器在软、硬2个方面的抗干扰措施。

Aiming at the existing problems of icing monitoring at home and abroad, the icing monitoring system of electrical power lines is studied according to the technical requirements of actual measurement. The strain of tension tower and micro- meteorological parameters are measured,and combined with the factors of electrical power line swing, the mathematical model for power line icing thickness calculation is deduced based on the mechanical analysis of icing measurement principle. A scheme of electrical power line icing monitoring system is designed according to the actual application environment ,which is based on micro -power single-chip MSP430F149. Some hardware circuits and software flowcharts are introduced and the anti -jamming measures are discussed in both software and hardware aspects.
