Abstract: |
In the light of increasing renewable feed-in and challenging market
conditions, flexibility requirements for hard-coal fired power plants become
more important. The focus is on the capability for primary and secondary control
response. In this work, a procedure has been developed using Kalman filters to smoothen stochastic oscillations of a Promecon coal dust mass flow measurement while capturing
the dynamic behavior during steep load ramps. The
filtered signal can be used to improve the performance of the power
correction controller in the power plant. A state controller with observer is proposed for this purpose, where
the observer is corrected by the power output measurement and the coal dust
mass flow measurement. Test results of the implementation in the control
system at Wilhelmshaven power plant show promising behavior
of the enhanced controller. |
