Top reliability is a must – the AC 800PEC in power generation

Typically, excitation systems are used for generator control in

power-plants where high reliability is the No. 1 requirement.

Due to the very short process cycles, traditional redundancy

concepts are no longer applicable.

The modular architecture of the AC 800PEC not only greatly

reduces the complexity of the overall system, but thanks to

redundant subsystems also provides increased reliability. In

the case of a problem in one subsystem, the main controller

switches over to the remaining subsystems, which are scaled

in such a way that the overall task can still be fulfilled. Should

the main controller fail, a second controller is available in hot-standby.

Precision for optimum quality – the AC 800PEC for industrial processes

The most demanding function in a rolling mill is thickness

control. By using the powerful AC 800PEC controller and its

ability to implement C-Code beside the standard IEC 61131-3

program level, a new thickness control solution for cold

rolling mills has been developed based on an MIMO (Multi

Input Multi-Output) control concept. The benefit to the

customer is an improvement in thickness deviation by up to 50 percent.
