Enhancement of situation awareness in wide area transmission systems for electricity and visualization of the global system state

One major task of the control centre operator is to identify the global system state of the transmission system. However, during the past couple of years, the complexity of transmission system operation has increased significantly. The operator in the control room has to observe wider external areas to fully evaluate system security. Along with the development of information technology and functionality of SCADA systems, the amount of data the operator has to monitor has augmented notably. The focus of this work is to develop a visualization of the global system state and to analyse and enhance situation awareness in wide area electrical transmission systems. In addition first versions of this new MMI are implemented into the SCADA system of the German TSO, Amprion. Thereby the study also enables usability engineering of variant new visualizations in the control centre. The proposed solution allows the operator to observe the global system state at a glance and enables intuitive situation awareness by improving visual perception like pattern recognition.
