Fig. 5.18.07: MAN Diesel’s Alphatronic 2000 Propulsion Control System
Alphatronic 2000 Propulsion Control System
MAN Diesel’s Alphatronic 2000 Propulsion Control
System (PCS) is designed for control of propul
sion plants based on diesel engines with CP pro
pellers. The plant could for instance include tunnel
gear with PTO/PTI, PTO gear, multiple engines on
one gearbox as well as multiple propeller plants.
As shown in Fig. 5.18.07, the propulsion control
system comprises a computer controlled system
with interconnections between control stations via
a redundant bus and a hard wired backup control
system for direct pitch control at constant shaft
speed.
The computer controlled system contains func
tions for:
•
Machinery control of engine start/stop, engine
load limits and possible gear clutches.
•
Thrust control with optimization of propeller
pitch and shaft speed. Selection of combina
tor, constant speed or separate thrust mode is
possible. The rates of changes are controlled to
ensure smooth manoeuvres and avoidance of
propeller cavitation.
•
A
Load control function protects the engine
against overload. The load control function con
tains a scavenge air smoke limiter, a load pro
gramme for avoidance of high thermal stresses
in the engine, an automatic load reduction and
an engineer controlled limitation of maximum
load.
•
Functions for
transfer of responsibility be
tween the local control stand, engine control
room and control locations on the bridge are
incorporated in the system.
