In this hydropower plant in the middle of Jämtland, an automation breakthrough has been achieved - the first in the world integration of power automation in the same System 800xA.
Flåsjö is an unmanned hydropower plant that is controlled and monitored by E.ON’s control center in Sundsvall. Process control and the electrical control system have previously been handled separately. When it was decided to replace the hydropower plant’s electrical and control systems at the beginning of 2009, it was natural to create a common system based on the new global standard IEC 61850.
“IEC 61850 is something we’ve included in our requirement specifications since 2005, but no one has previously been able to tender such a system. When ABB gave us the opportunity, we couldn’t say no,” says Assar Svensson, responsible for technology related to control and monitoring systems at E.ON Vattenkraft (the company’s hydropower division).
The technology is not just reserved for power plants. Regardless of industry, System 800xA can be used to integrate power automation systems into the same systems that handle the process automation. This enables improved monitoring capabilities, higher availability and simplified engineering.
