Optimized Design of Steam Turbine Control System

The steam turbine regulating system is an important link of a steam turbine generator unit. The operating effect of the steam turbine is determined by the quality of control of the regulating system. In this paper, a particle swarm algorithm and fuzzy PID control are combined according to the regulation principle and characteristics of a steam turbine digital electro-hydraulic regulation system (DEH). Respective advantages of two control methods are taken to control the parameters in a loop and regulate the control quality of the system in real time according to the operation deviation change of the DEH control system. Finally, the system is better controlled.
