Deals with the definition and the characteristics of control systems. It is not limited to the actual controller tasks but also includes other tasks which may be assigned to a control system, such as sequence control tasks, safety and provision for the actuating energy. The following systems are included, speed, power, opening, water level and flow control for all turbine types; electronic, electrical and fluid power devices; safety devices as well as start-up and shutdown devices.
