MCS: Simulation results 6: Supp Burner ein 8: Supp Burner off 12: ca. 30 Pulses per hour, is ok 1: Engine on 2: Generator connected 10a: Supp Burner ein 3: THead controlled very nicely! 4: Fan drives EngBu back 9: Due to overshoot of TBoiler, THeadSp is reduced. Is this reasonable? Point to discuss! 11: Modulation of supp Bu is enabled after nach 10 Min 5: TBoiler remains below setp 7: TBoiler overshoots due to min heat output of SuppBu 10: Step of TBoiler setp 60°C Copyright © Siemens 20 Oct 2009 C.
