St. Göran Hospital

Skara - Stockholm 2014

---

Located at Fridhemsplan on Kungsholmen is one of Stockholm's most central emergency hospitals, St. Göran. The hospital is also one of the country's largest emergency hospitals in terms of the number of emergency patients received annually. The current hospital is over a hundred years old, with origins dating back to the 13th century.

To meet the safety requirements of a modern hospital, the power supply and control system needed to be modernized. As a subcontractor to Linjemontage AB, the task was to replace and upgrade the existing control of the operation of all power to St. Göran.

The requirements of the facility mean that it must never be de-energized. Together with a partner, Provektor worked for over a year to design and program a new advanced control system.

The challenge is solved by feeding electricity from three different parts of the city. In the event of disruptions to the external supply, a battery backup is connected automatically and the power supply to the hospital's various functions is reprioritized. Then, heavy-duty diesel generators that can run for a long time are started. When the grid is deemed reliable again, the control system automatically phases it back in and all hospital functions return to normal operation.

The control system now also allows a third party to monitor the function via measuring instruments. Electricity and heat consumption can also be regulated by the new system. The work was completed in 2014.

Provektor has similar tasks at the hospitals in Kalmar and Västervik.
