A control method for the analog input / output setting mode of a hydro-generator monitoring system includes a newly added program for identifying input / output pulses. The control logic is as follows: ① If an input pulse command of 1 is detected, the analog input / output setting value = analog input / output setting value + fixed step size; otherwise, the analog input / output setting value remains unchanged. ② If an input pulse command of 1 is detected, the analog input / output setting value = analog input / output setting value - fixed step size; otherwise, the analog input / output setting value remains unchanged. A new analog input / output setting value initialization program is also included, employing the following control logic: When other control modes are switched to analog input / output setting mode, the current input / output setting feedback value sent by the governor is assigned to the analog input / output setting value as the initial value. This invention can improve the guide vane opening and active power regulation speed, enhance equipment stability and reliability, reduce intermediate links and fault points, lower equipment failure rate, and ensure the safe, stable, and high-quality operation of the generator unit and the power grid.
