For a long time, we have been doing maintenance of their SAS2000 control system, which controls local distribution network. In 2020 we have done upgrade to Mark II version without interruption of service. This upgrade will be finished in 2021.
The control system in Mondi manages substations at 110kV, 11kV, 6kV levels and several generators with power output up to 63 MW. It provides control, signals blocking, control of synchronization a island mode operation. In 2021 we have implemented new software module for load shedding and prevention of tripping input transformers protections (load shedding based on transformer load).
