Breaking the rules brings about progress
Just over a month after Peter Schult presented his idea to the R&D team, he and Markus Aebi were able to tackle a simplified representation of the Swiss extra-high-voltage grid for the first time. Today they both look back on their work with satisfaction. Peter currently works as a Senior Application Specialist and has completed further training in visualisation technologies. As a former operator in Grid Operations, he is very familiar with the conditions in the extra-high-voltage grid. Markus, a Digital Media Manager and qualified machine draughtsman, has an excellent grasp of the necessary skills and design software.
Together, they clearly visualised the entire grid to enable a better and more intuitive orientation for the specialists in the grid control room. This required them to abandon some of the rules. For instance, Peter and Markus did not replicate the topography of Switzerland. In the new representation, the lines only run horizontally, vertically or at a 45° angle. Line intersections were eliminated wherever possible, densely packed areas expanded and better use was made of areas with fewer lines. In addition, they established line symmetries and made of the course of line rings clearer. In doing so, Peter and Markus were always firmly focussed on the goal of making sure that the topography remained clearly recognisable.
Another rule that they broke was the colour of the 380 kV lines. These lines had previously always been red. Red is a signal colour and is no longer used when the grid is in its normal state in the new representation. This naturally makes it possible to expand the range of signal colours, with yellow and orange for example. Irregularities in the grid can now be divided into clear priority levels that can be easily identified by operators in the grid control room.
