Hydro turbine control system for better plant usability

Perfect coordination of turbines, plants and fleet

Valmet has extensive experience with Kaplan, Francis and Pelton turbines – from small to very large machines. Valmet’s know-how includes overall hydropower control strategies, including water balance control, frequency support applications and power plant fleet management. This makes our solution an ideal match for both retrofits and greenfield hydropower plants.

We have developed a long-term partnership with Valmet across our other hydropower plants. As Valmet has successfully retrofitted hydro turbine automation with Valmet DNA at our Siikakoski hydropower plant, we aimed to implement a similar solution for the Verla plant, too. A unified automation system across all sites, including engineering tools and data collection, ensures that only one system requires future upgrades.”

KSS's Finnish press release regarding the delivery

In supplier selection Valmet showed flexibility and provided fast responses to our needs. After testing the functionality with third-party systems, we were convinced of the Valmet DNA central control system. Additionally, we appreciate Valmet’s strong service support close to our key locations. As reliability is very important for us, we wanted the system and connections to be fully redundant. And what’s more, base system reliability needs to be top-class to enable hydropower operations.”
