Veresen Inc. is a large energy infrastructure company based in Calgary, Alberta. It has main businesses in pipelines, natural gas and power generation, with three hydropower projects operating in British Columbia. Hydropower is an important source of renewable energy, and plays an important role in all provinces in Canada, particularly in British Columbia, Manitoba and Quebec. Power transformers are critical components in electricity generation and transmission systems. It is important to ensure the reliable operation of transformers, and their failures will lead to very expensive downtime. An important way to improve transformer reliability is performing health condition monitoring and diagnosis via periodic inspections. In this project, we will develop advanced methods and tools for transformer fault diagnosis and prediction based on artificial intelligence techniques, by fully utilizing the transformer data at Veresen, such as the dissolved gas analysis (DGA) data and oil quality data. The methods and tools to be developed will also be validated using field data. This project will help to improve the system reliability and safety, and reduce the overall operations and maintenance cost at Veresen's hydropower generation plants in Canada. The generated knowledge and tools can potentially benefit the hydropower industry, as well as other engineering systems, such as power networks, renewable energy systems and manufacturing systems.

Veresen Inc.是一家位于阿尔伯塔省卡尔加里的大型能源基础设施公司。它的主要业务是管道、天然气和发电，在不列颠哥伦比亚省有三个水电项目。水电是一种重要的可再生能源，在加拿大各省，特别是不列颠哥伦比亚省、马尼托巴省和魁北克省都发挥着重要作用。电力变压器是发电和输电系统中的关键部件。确保变压器的可靠运行是非常重要的，它们的故障将导致非常昂贵的停机时间。通过定期检查对变压器进行健康状态监测和诊断是提高变压器可靠性的重要途径。
