The Finnish Power System Control Centre

The operating philosophy for controlling the Finnish power system is based on production conditions, which include hydro, nuclear and coal-fired power plants, and joint national and international operation. On top of the control hierarchy is the Control Centre which has eight District Centres under its command. The Control Centre system, which was placed in full operation in 1982, consists of three subsystems: the Main, the Front-End and the Automatic Generation Control Computer systems which together with the District Centre Computer systems form an extensive computer network. The Main Computer system includes the most common SCADA-functions and EMS features such as State Estimation, Operators Load Flow and Load Forecasting among others.
