南水北调中线干线工程户外监测设备的智能供电方案设计

Design of Power Supply System for Outdoor Equipments in South-to-North Water Diversion Middle Route Project

摘要: 南水北调中线干线工程是全球最大的人工调水工程，全线总干渠长约1432公里，建成后将对我国京津冀经济圈乃至全国经济与社会发展发挥重要的促进作用。但是，全线输水距离远、工程实体多，跨越区域地质条件不同、人文环境各异，这些复杂条件给中线干线工程的安防带来严重挑战。本文结合中线干线工程安防系统户外设备的供电需求，分析了引民电供电的不可行性，给出了现地通信站周边及渠道上的供电设计，包括从现地通信站引电及太阳能供电系统设计，并指出了未来智能电网在该系统中应用的方向。本文的研究成果可以为后期安防系统的建设提供有效支撑。

Abstract: South-to-north water diversion (abbreviated as NSBD) project is the world’s largest artificial water diversion project, with a total length of roughly 1432 kilometers. The construction and operation of this project will be a promoting factor to China’s economy and society development. However, the distance of the canal is too long, and there is a variety of geological conditions and cultural environments along the canal, which brings a lot of challenges to the monitoring and operation of this canal in the future. In this work, with practical experiences during the construction of this canal, a thorough analysis of power supply system for the outdoor equipments of future security monitoring systems has been provided. Specifically, infeasibility of exploiting residential power supply system is demonstrated. Then two different types of power supply means, i.e., alternating current power supply with electrical cable and solar power supply. Finally, directions of the applications of smart grid technologies in this canal are pointed out. The research achievements in this work will facilitate future development of security monitoring systems for NSBD project.
