Large gas turbine generator set is a complex system

and it is difficult to accurately control the low frequency oscillation in the case of multi-component coupling.Therefore

it proposes an automatic control method for low frequency oscillation of large gas turbine generator set.It determines accurately the low frequency oscillation source of gas turbine generator set.Based on this

the control parameters are obtained to complete the automatic control of low frequency oscillation of gas turbine generator set.The experimental results show that the research method can accurately determine whether there is low frequency oscillation in the gas turbine generator set

and the output power of the large gas turbine generator set is higher and the fluctuation is smaller after the application of the method

which verifies the effectiveness of the research method.
