Double adjusting unit means the turbine whose guide vanes' and blades' opening or angle can be adjusted according to the site operation so as to achieve optimal efficiency operation. The unit has a complex control system, which requires the good performance and high accuracy equipments. Therefore,the control, maintenance, state detection and management functions of the control system must be integrated through introducing modern information and intelligent technologies. The reliability,economy and regulation performance of the control system will be improved continuously through optimization based on the design characteristics and operating state of different control systems. The paper focuses on how to improve the reliability and safety of automatic control system of double adjusting unit through optimizing its logic functions.
