Visualization of Power System Data on Situation Overview Displays

Findings from field studies in power system control rooms show that overview displays are needed to aid operators to achieve shared situation awareness. The existing overview displays are often cluttered, with a lot of detailed information and with overuse of colors. There is no "best practice\´\´ in the field and it is up to power system utilities to design their own displays. This work presents a survey of previously proposed mappings of power system data to visual representations and based on this analysis a set of alternative mappings are demonstrated.
