High flexibility thanks to flexible software
SPPA-P3000 solutions for enhancing flexibility without modifying the hardware is enjoying growing popularity especially in the liberalized markets. MaxLoadPlus makes it possible e.g. to boost power output to 110% on the basis of control actions alone – as has been demonstrated in practice! A profitable investment that pays off in next to no time!
SPPA-P3000 solutions for high flexibility allow optimum response to changing load demands. The control concept together with extension of the operating range of the subordinate controls to cover higher maximum and lower minimum loads lay the foundations for flexible and at the same time stable operation.
Our Solutions:
- SPPA-P3000 Fast Start: Fast startup
Minimizes startup time while ensuring that thermal stresses on thick-walled components do not violate permissible limits. Usually accompanied by a significant reduction in fuel consumption.
- SPPA-P3000 Fast Ramp: Fast load ramps
Coordinates steam generator and turbine, mobilizing stored energy in the power plant process to give precise and repeatable load changes.
- SPPA-P3000 Minimum Load Reduction: Reduction of mimimum load
Reduces the minimum load level at which a unit can run and thus minimizes the financial losses sustained in periods when the selling price of power is lower than the generating cost. This is particularly beneficial in the case of oil- and gas-fired units which cannot be shut down completely, e.g. because they have to supply district heating systems.
- SPPA-P3000 Maximum Load Plus: Increase in maximum load level
Boosts electrical output to up to 110% of rated capacity at unchanged main steam mass flow by smooth and controlled full or partial deactivation of the HP feedwater heaters without modifications to the hardware. There are times when high power prices on the spot market can make it highly lucrative to operate the plant at above rated output.
- SPPA-P3000 Frequency Control: Primary frequency control
Permits reliable and cost-effective provision of primary frequency control and spinning reserve.
- SPPA-P3000 Dispatch Control: Load cycling and dispatcher control
Load cycling under dispatcher control to provide secondary frequency control capability is becoming a more and more lucrative service, but due to the fast load ramps required it places very high demands on the dynamic control response of a power plant unit. DispatchControl permits reliable and cost-effective provision of secondary frequency control capability.
