Complex Parallel Operation with Parametrizable Control Devices

At this example project structural demands of the building needed to be met: Cable connections between the controls are very long, because the emergency power supply gensets including the related controls are located in another part of the building than the central control panel.

Cabling work was supposed to be reduced to the minimum possible for this reason. Additionally it was important to the customer, that the remaining cable connections should be redundant, because these are functionally relevant connections.

This is why we decided for the "Deif Concept".

Deif Concept - Deif Concept Solution

The three central control panels consist of:

  • two AGC4 Mains controllers, to control and monitor mains supplies
  • two AGC Tie controllers, to control and monitor the generator coupling-breaker
  • one plc control for the progressive switching of outgoing breakers

Function

  • All Deif control devices are connected with eachother by a redundant CANBUS and send functional relevant information. Due to long cable connections the redundant CANBUS is converted into optical connection by media converter.
  • Important information from central control panel is sent to the genset controls by CANBUS data connection (without additional cabling work). The emergency power supply operation, loading test in mains parallel operation, mains import/export control or full load test for the emergency power gensets are started by this connection.
  • Due to a split of the whole function into several control devices, a failure of one device does not result in the loss of the complete function. Several functions will still be possible.

Even complex applications can be realized by compact controllers. During tendering stage the different solutions should be compared technically and economically .
