SOFC power generation system control method based on state machine

The invention relates to an SOFC power generation system control method based on a state machine, the SOFC power generation system control method is applied to the state machine of an SOFC power generation system, the running states of the SOFC power generation system comprise an initialization state, a heating state, a heat preservation state, a power generation state, a cooling state, a fault state and a shutdown state, and the power generation state comprises a zero-power power generation state and a normal power generation state; a heat preservation state is set, so that the SOFC power generation system is always in a high-temperature state after being heated once and can generate power at any time, long-time waiting for heating each time is avoided, and the efficiency is improved; a zero-power generation state is set, so that the SOFC power generation system enters a power island mode, shutdown of the SOFC power generation system can be avoided when a public power grid breaks down and needs to be maintai
