Application of Step-Servo Motor Electricity-Displacement Converter to Turbine Governor
This paper analyzes the control and characteristics of electricicity-displacement converter of traditional stepper motor and AC servo motor on the turbine speed governor.Considering the advantages and disadvantages of stepping and AC servo motor control methods,a stepping servo motor has been applied to the electricity-displacement converter of turbine speed governor,and the control method has been technically improved.The pilot valve displacement feedback link was cancelled,positioning control was made through analog quantity and successfully applied to the turbine speed governor.The performance indicators meet the requirements of national standards.This paper elaborates the proposed method.
