AC 800PEC modular architecture in an excitation system: top reliability through redundant subsystems and distributed control logic
Well suited to a harsh environment - the AC 800PEC for traction
Traction with its particularly harsh environmental conditions is one of the most important applications of the AC 800PEC. The controller operates through a wide temperature range (- 40 to + 70 °C), with vibrations according to traction standards. The compact solution is the ideal response to the demands of restricted spaces and allows integration of the processing unit together with all the I/Os in the same compact hardware device.
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 Due to the very short process cycles, traditional redundancy concepts are no longer applicable.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.
