The conventional thermal power units have disadvantages of large inertial and delay in unit coordinated control system.The condensate throttling technology can realize rapid increase in load response speed of the unit

but there is a problem of excessive regulation.The fuzzy adaptive PID controller can take advantage of the PID parameters and online adjust the PID control parameters according to the fuzzy rules when the error and error deviation changes

to improve the dynamic and static performance of the controlled object.Combining with the operation characteristics of the coordinated control system of a 600 MW thermal power unit

this paper proposes to apply the fuzzy adaptive PID controller to the condensate throttling technology.The simulation results show that

the condensate throttling technology can improve the load response rate of the unit and mitigate the condensate throttling technology's overreaction

the system performance and economic benefits of the thermal power unit increased effectively.
