Switching Control Strategy Study of Dual-fuel Gas Turbine

In order to ensure the rapidity and stability of dual-fuel gas turbine in the fuel-switching process, this paper proposes a dual-fuel gas turbine switching control strategy. This method can ensure the stable control of the switching process of the dual-fuel unit, make the unit quickly complete the transition process of the two kinds of fuel-switching, so as to realize the fast and stable control of the dual-fuel unit. In this paper, the process of gas-oil switching of the dual-fuel engine has been carried out by the digital simulation software. The simulated results show that the strategy can realize the fast switching control between natural gas and diesel oil in an emergency.
