摘要:

在线监测技术在输电线路中的推广应用,使输电线路从传统的以人巡检为主进入到了以状态检修为核心的运行维护方式,为输电线路的数字化、智能化管理提供了可靠的依据,在线监测装置的广泛应用是发展坚强智能电网的必然要求[1]。然而蒙东大兴安岭地区地形情况复杂,是典型的微气候区域,特别是在冬季,容易出现低于−40℃的极寒天气,输电线路经常发生覆冰、舞动跳闸事故,常规在线监测装置在蒙东极寒天气下无法有效稳定运行,本文对导致常规在线监测装置在蒙东极寒天气下无法正常运行的供电、装置可靠性和通信等三大关键问题进行了研究,并提出了有效的解决办法。

Abstract: The application of online monitoring technology in power transmission line enables the transmission line to come to a new operation progress in which condition-based operation plays the main role instead of the traditional people-oriented operation, which provides a reliable basis for the digital, intelligent management of transmission line. Therefore, the wide use of on-line monitoring devices is the necessary requirement for the development of Strong Smart Grid. The Khingan area in eastern Inner Mongolia is covered in the typical micro-climate region, where the temperature always declines to −40˚C, especially in winter, and it is likely to cause transmission line to freeze and results in tripping accidents. That is to say, traditional on-line monitoring devices can not be effectively operated in the arctic weather. In this paper, three key issues: the inefficient power supply, low reliability, and communication condition of the traditional on-line monitoring devices operating in the arctic Mongolia areas have been discussed, and effective solutions are also mentioned.
