Enhancement of Unit Primary FM Performance Using High Precision Frequency Difference Controller
The main problems faced by the primary FM of power plants include the deviation between the network frequency and the unit turbine speed overrun moment,the 15 s contribution index,the 30 s contribution index,the integral power contribution index does not meet the requirements,and the unit speed measurement is not accurate enough,etc.To address the above problems,a high-precision speed controller is used to improve the performance of the unit primary FM.Aiming at the above problems,a high-precision speed controller is used to improve the performance of primary FM of the unit,and the effect is obvious.
