Design and application of automatic monitoring project for reservoir water temperature

为了研究某在线调蓄水库冬季的水温调节问题,分析水库水温的垂向变化及时空分布规律,特在某水库制定水温自动化方案并予以实施。首先采用先进的进口设备温深仪CTD调查水温沿深度的分布情况,以确定传感器的安装深度。再将温压一体传感器按设计位置固定在钢缆上,采用水温自动化设备采集不同深度的水温数据,并实时上传到水温数据平台进行分析和展示。经过2020—2021年4个月的数据观测,该水温自动化监测系统运行正常,已取得了一个冬季完整的水温数据,初步了解冬季水温变化规律及垂向水温分布情况,对解决调蓄水库的水温调节问题具有一定的参考价值。

In order to study the water temperature regulation of an online storage reservoir in winter, and to analyze the vertical variation and temporal and spatial distribution of the water temperature, a water temperature automation scheme is developed and implemented in a reservoir. First, an advanced imported temperature depth meter(CTD) is used to investigate the distribution of water temperature along the depth to determine the installation depth of the sensor. Then the temperature and pressure integrated sensor is fixed on the steel cable according to the designed position, and the water temperature data of different depths are collected by water temperature automation equipment, and then uploaded to the water temperature data platform in real time for analysis and display. After more than 4 months of data observation from 2020 to 2021, the automatic water temperature monitoring system runs normally. A complete winter water temperature data has been obtained, and a preliminary understanding of the variation of winter water temperature and vertical water temperature distribution has certain reference value for solving the problem of water temperature regulation in the reservoir.
