A hydropower plant set out to upgrade and modernize its systems to achieve more efficient power generation. Unlike traditional setups, modern hydropower facilities utilize a combination of integrated systems to enhance performance and stability while keeping costs down. Historically, key components—such as excitation systems, governing mechanisms, spiral casings, penstocks, and water turbines—operated on separate network protocols. Maintaining these fragmented networks was expensive and required additional engineers and complex infrastructure.

System Requirements

• Deploy an AI system on the control network to access data in real time while maintaining the performance and safety of power generation facilities and without occupying bandwidth designated for critical control data.
• Utilize a unified network to integrate different applications for seamless communication.
• Ensure support for Gigabit communication.

To address these challenges, the operating company decided to unify their isolated networks and integrate an AI-driven control system by implementing time-sensitive networking (TSN). This approach was ideally suited for their needs. Firstly, consolidating diverse applications into a single, unified network simplified the network architecture, resulting in significant cost savings. This streamlined structure also provided high-speed data transmission, precise control, and robust network security. Secondly, TSN resolved interoperability issues between the existing control network and the new AI system, enabling a seamless AIoT (Artificial Intelligence of Things) solution.

Moxa’s TSN-G5008 Ethernet switch played a pivotal role in this transformation. With its 8 Gigabit ports, the switch connected all the plant’s control systems, creating a unified and efficient network. The switch’s high bandwidth and low latency capabilities facilitated real-time communication of large data volumes, crucial for the AI system’s performance.

The outcome

The hydropower plant achieved greater efficiency and could swiftly adjust power output to meet grid demands. This modernization resulted in reduced costs, easier maintenance, improved efficiency, and enhanced adaptability, marking a new era for the facility.
