Description: The Digital Governor System (DGS-8800e) is a complete package which fulfills all tasks for governing the speed of low-speed, long-stroke diesel engine of the Sulzer RTA type manufactured by Wärtsila NSD and their licencees. The speed setting may be from three different systems, usually the remote control system (AutoChief 4 or AutoChief 7), local control panel, and control room back-up panel (optional).
The system may be fitted to both fixed pitch and controllable pitch propeller systems (FPP and CPP systems). The system responds to slow-down and shut-down signals from external safety systems. Fuel-saving features, such as load limiting functions, are included.
The DGS 8800e performs computerized handling of all measurements and control signals. It includes panel push-button flexibility to select, adjust, and test the system performance. Movement of the fuel rack is done by an electric actuator, with a 3 phase brushless servomotor as the power medium.
The main purpose of the DGS 8800e system is to control the position of the engine fuel servo, in order to maintain an engine speed equal to a reference setting. The system is composed of two separate and self-contained subsystems, the speed Regulating Function, and the fuel Actuator Function.
The speed pick-up sensors are of an inductive type, mounted towards engine gearwheel inside the main engine. They are completely duplicated for increased system reliability.
Engine charge air pressure is measured to be able to limit the fuel injection according to charge air pressure value.
For CCP systems, the pitch value is input to compensate for loading conditions.
The speed reference input to the system may be one of three, selectable either from the remote control system (from bridge or control room), the local control panel, or the control room back-up panel.
The DSU (Digital Servo Unit) which is supplied from the AC mains, supplies the DGS 8800e system with 24V DC.
The ELACT (Electric Actuator) is supplied by a 3 phase AC main power supply through a TRAFO 001 (transformer) and the DSU with power and servo amplifier. The Actuator Feedback Transducer is a high resolution absolute encoder with contactless displacement to improve system reliability.
