Abstract
Test methods for parameters of steam turbine and its governing systems were investigated.The effect of such factors as control logic
field signal acquisition method
input/output characteristics testing of the PID controller on parameter identification was analyzed.It was pointed out that improper measuring method would affect the parameter identification and accuracy of simulation check.Therefore
checking based measuring methods for parameters of steam turbine and its governing systems were proposed
according to the requirements of Q/GDW 748-2012 Guide for modeling and testing of generator's prime mover and governor.
