| Abstract | SUMMARY During the past couple of years, the complexity of transmission system operation has increased significantly. Along with the liberalization of the electricity markets a broad range of new, varying tasks have arisen and with this a growing number of interfaces which the control centre operator has to cope with. Furthermore the substantial growth of volatile wind and solar energy sources and largescale energy trades across wide-areas lead to frequently changing load flow situations. As a consequence of these huge load flows, the power system is operated ever closer to its security limits. The operator in the control room has to observe wider, external areas – with less operational experiences compared to the own grid – to fully evaluate system security. Along with the development of information technology and functionality of SCADA systems, the amount of on- and off-line data the operator has to monitor has augmented notably. One major task of the control centre operator is to identify the global system state of the transmission system. This serves as basis for decision making. The growing complexity in the control centre poses new demands on the visualization concept according to cognitive principles. Therefore this paper describes the concept and implementation of an approach, how the increasing complexity can be prepared to assist the operator in the control centre. 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 man-machine-interface (MMI) are implemented in the SCADA system of a German TSO. 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. |
