Method for real-time automatic diagnosis and intelligent correction of governor main distribution electric neutral position

The invention discloses a method for real-time automatic diagnosis and intelligent correction of a governor main distribution electric neutral position. The method comprises a governor main distribution electric neutral position drifting automatic diagnosis method and a governor main distribution electric neutral position intelligent correction method. The governor main distribution electric neutral position drifting automatic diagnosis method comprises the steps that a governor electronic control system collects data such as guide vane opening given Y and the main distribution position givenM adjusting period output by a governor hydraulic follow-up system PID module in real time; whether the relevant data meet the criterion of governor main distribution electric neutral position drifting or not is judged; if yes, diagnosis is stopped, and a main distribution neutral position intelligent correction link is entered; and if not, returning is conducted to continuously collect the data in real time for main dist
