Thermal generator set coordination control system based on internal model control structure

The invention discloses a thermal generator set coordination control system based on an internal model control structure. The thermal generator set coordination control system comprises a load demandprediction module, a first internal model prediction control module, a second internal model prediction control module and a direct energy balance module, the first internal model prediction control module is also used for predicting the load demand variation; calculating an amount of change in fuel demand, the second internal model prediction control module is used for predicting the fuel demandvariation generated by the pressure change of the boiler; the sliding pressure operation of the automatic power generation control system of the thermal generator set is realized; the climbing rate K1of the automatic power generation control system is improved. The method has the advantages that the adjustment precision K2 is stabilized; the response time K3 is shortened; the purpose of optimizing the control parameter Kp
