The invention provides a control program of an oil-free water lubrication screw air compressor, which comprises a startup control program, and the startup control program comprises the following steps: 1) before the air compressor is started, judging whether the air compressor is in a fault state or not, if so, not normally starting the air compressor, and starting the air compressor after removing the fault; if not, entering the step 2; 2) judging the water level, and draining or supplementing water if the water level is higher or lower so as to ensure that the water level is at a proper position; (3) after the water pump is started, if the water pressure is detected to be too low, the system alarms and stops; if it is detected that the water pressure is normal, the host starts to accelerate to the lower limit frequency to operate, and after pre-operation is conducted for a period of time, frequency loading operation is automatically controlled through an internal program PID algorithm, so that the exhaust p
