摘要：In the paper a synthesis of advanced control structures of turbine and synchronous generator for nuclear power plant working under changing operating conditions (supplied power level) is presented.It is based on the nonlinear models of the steam turbine and synchronous generator cooperating with the power system.The considered control structure consists of multi-regional fuzzy control systems with local linear controllers, including PID controllers,in particular control loops of turbine and generator.Soft switching between the local controllers is performed by the Takagi-Sugeno-Kang fuzzy logic mechanism.Parameters of the local controllers were optimally tuned for a priori chosen operating points within the range of 50–100% of nominal active power generated by the synchronous generator.Simulation results show that proposed advanced control structure is superior to widely used classic control structure (local controllers tuned for nominal operating points).During simulations the data of the real devices was used,respectively for the 4 CK 465 steam turbine and synchronous generator GTHW-600,which were planned to be used in the first Polish nuclear power plant in Żarnowiec.
