AK St. Georg | Hamburg, Germany
Mains power supply, medium voltage units, Siemens S7-400H, Siemens TP 1900
The net replacement supply for the Ak. St. Georg is guaranteed by 2 medium-voltage units, each with a rated output of 2700 kVA.
The control of the 8 external power and coupling switches is realized via a central control. In the event of an emergency, the AV supply can also be fed with the power units in addition to the SV supply.
The unit controllers as well as the central controller are equipped with a redundant S7-400H, which compensates for a failure of the CPU.
The plant-relevant data is displayed on a Siemens TP 1900 in the central control system and the aggregate-specific data is displayed on a Siemens TP1900 of the aggregate controllers. In addition, selected informations are forwarded to the network control system via a Modbus TCP / IP interface.
2 x Genset control
1 x Central control
2 x Control panel TP1900 for the genset control
1 x Bedientableau TP1900 for the central control
