Hospital ATS - Dynamic Load Contol / Load Shedding

This system was developed for a major 722 bed + A&E “Super” hospital in the UK West Midlands.

Five large emergency standby generators provide the standby power solution for this major hospital. In times of a power outage the 5 generators individually start and are gradually paired by synchronising to form one generating source. The electrical loads are shared between 3 large LV switchboards in various locations across the hospital.

In the event of a power outage the dynamic load control system sheds all non-critical loads, to reduce the load to a level within the start capacity of each individual generator. On generator start and connection, loads are connected according to a priority table and the measured available generator capacity. As generators synchronise and pair up, the load priority table is changed to suit the new generating configuration. v During operation individual loads can be connected or disconnected according to the priority table and the measured available generator capacity or configuration.
