摘要

稳定的电力供应对工业活动和经济发展以及人类福祉至关重要。因此,电气系统设备配备了监控系统,以方便其管理并确保不间断运行。这就是电力变压器的情况,它通常有监测系统,允许早期发现异常,以防止潜在的故障。这些监测系统通常使用与变压器设备物理接触的传感器,因此可能受到变压器问题的影响。在这项工作中,我们展示了一个基于热像仪获得的温度测量的电力变压器监测系统。适当的定位,摄像机提供变压器,输入和输出线路及其周围环境的热数据。随后,通过适当的图像处理,可以获得温度序列来监测变压器的运行情况。此外,该系统在外部设备(放置在变压器以外的位置)中存储和处理热数据,并配备了一个通信模块,允许独立于电网的安全数据传输。这方面,以及不需要与变压器进行物理接触的事实,使这种方法比基于传感器的标准方法更安全,更可靠。该系统已在西班牙电网的14个站点进行了评估,获得了准确可靠的温度时间序列。

Connected system for monitoring electrical power transformers using thermal imaging
The stable supply of electricity is essential for the industrial activity and economic development as well as for human welfare. For this reason, electrical system devices are equipped with monitoring systems that facilitate their management and ensure an uninterrupted operation. This is the case of electrical power transformers, which usually have monitoring systems that allow early detection of anomalies in order to prevent potential malfunctions. These monitoring systems typically make use of sensors that are in physical contact with the transformer devices and can therefore be affected by transformer problems. In this work we demonstrate a monitoring system for electrical power transformers based on temperature measurements obtained by means of thermal cameras. Properly positioned, the cameras provide thermal data of the transformer, the incoming and outgoing lines and their surroundings. Subsequently, by appropriate image processing, it is possible to obtain temperature series to monitor the transformer operation. In addition, the system stores and processes thermal data in external equipment (placed in locations other than the transformers) and is equipped with a communications module that allows secure data transmission independent of the power grid. This aspect, along with the fact that there is no need to have physical contact with the transformer, make this approach safer and more reliable than standard approaches based on sensors. The proposed system has been evaluated in 14 stations belonging to the Spanish power grid, obtaining accurate and reliable temperature time series.

期刊介绍: Integrated Computer-Aided Engineering (ICAE) was founded in 1993. "Based on the premise that interdisciplinary thinking and synergistic collaboration of disciplines can solve complex problems, open new frontiers, and lead to true innovations and breakthroughs, the cornerstone of industrial competitiveness and advancement of the society" as noted in the inaugural issue of the journal. The focus of ICAE is the integration of leading edge and emerging computer and information technologies for innovative solution of engineering problems. The journal fosters interdisciplinary research and presents a unique forum for innovative computer-aided engineering. It also publishes novel industrial applications of CAE, thus helping to bring new computational paradigms from research labs and classrooms to reality. Areas covered by the journal include (but are not limited to) artificial intelligence, advanced signal processing, biologically inspired computing, cognitive modeling, concurrent engineering, database management, distributed computing, evolutionary computing, fuzzy logic, genetic algorithms, geometric modeling, intelligent and adaptive systems, internet-based technologies, knowledge discovery and engineering, machine learning, mechatronics, mobile computing, multimedia technologies, networking, neural network computing, object-oriented systems, optimization and search, parallel processing, robotics virtual reality, and visualization techniques.
