THE CHALLENGE:
Distribution Operations Center (DOC) operators could not see, much less act on the information displayed on their existing SCADA screens despite their overview displays being right in front of the them. You can see from the pics, the lower overview displays are behind their main, large format HMI screens.
The problem was even worse when their Sit-Stand consoles were raised up and blocked both rows of overview displays….so they contacted SLA for help.
At first, the client was thinking about flipping their console desks 180 degrees away from the overview screens. But, this would create a major issue for operators, because they’d constantly have to turn around to view their overview screen data – this is not a recommended best practice.
THE SOLUTION:
Improve the operator’s situational awareness. The consoles were redesigned to allow operators to face the overview screens in both a sitting and standing position. Bezel-less, view wall display systems were integrated into the primary SCADA positions and the operator has use of 2 of the 12 large format displays directly at the console.
The new, custom consoles formed an effective control environment and allows operators to use and see their SCADA data from their primary position…at the console.
Auxiliary monitors can be raised directly in front of the operator in either a sitting or standing position. During upsets, their span of control is increased where additional display data is required.
The control room lighting is designed to achieve vigilant light levels without any observable fixtures hanging down and helps create an even distribution of light throughout the room. The ceiling panels also help address acoustical absorption needs and supplies air circulation for the HVAC system according to industry best practices.
