Design and Application of Feed Water Control System for Super-critical Power Generation Unit
The characteristics of super-critical power generation unit coordinated and feed water control system are strong coupling of multiple inputs and multiple outputs,non-linearity,time-varying parameters.Design object of the study work is that controlled systems are controllable and stable.Two type of the practical running power were used as research object,the control system was designed accordingly.At first,the preconditions and proofs of stability of coordinated control system (CCS) and feed water control system (FWCS) were given respectively,then stability analysis for CCS and FWCS were made by mathematical derivation according to the technical problems of FWCS.The application results of super critical power unit show effectiveness and practicability.
