High availability thanks to lower "stress"
Availability continues to be top priority on the specifications list of many operators. Understandably so, because a power plant on an unscheduled outage not only costs money, it also pulls down the overall output balance. PROFI LowStress is a successful example of how a lot can be achieved at low cost
The feedforward control consistently implemented in the PROFI Solutions allows fuel overfiring to be reduced and the number of control actions to be kept to a minimum. This helps to reduce service life consumption effects on components. The tried-and-tested load-capability circuit enables the plant to cope with the loss of major components without tripping.
Our solutions:
- SPPA-P3000 Runback Plus: Ability to ride out loss of major components
In the event of loss of a major component such as a feedwater pump or an induced-draft fan, this feature automatically performs stable and reliable fast runback of the plant to the new maximum load level that is permissible without the component concerned, avoiding outage of the entire unit.
- SPPA-P3000 Life Time Plus: Low-stress plant operation
Thanks to its predictive feedforward control and mobilization of stored energy, this feature enables stable and precise load changes with minimum fuel overshoot. This minimizes wear and tear on the plant components
