Automatic control method and device for gas generator set

The invention provides an automatic control method and device for a gas generator set, and the method comprises the following steps: S1, responding to a start key pressed by a user; S2, determining the opening condition of a gas electromagnetic valve according to the air-fuel ratio data; S3, adding the delay time after the motor is withdrawn under the condition of successful starting; S4, after the starting is successful, maintaining the idling operation; S5, after the unit reaches the rated speed state and stably operates for a preset t2 time, monitoring whether the voltage and the frequency reach synchronization detection conditions or not, and monitoring whether the voltage, the frequency and the phase angle of the power generation and the mains supply reach the synchronization conditions or not; S6, after switching on, enabling the control system to automatically perform step- by-step loading according to preset target power in an automatic loading state. The invention has the beneficial effects that the
