Abstract:
Investment in control systems has become an important factor in
production increasing and cost reduction, this led to high competition
between the companies of production for the development of control
systems; PLC has become a widely used and essential in the field of
.industries such as chemicals, petrochemicals, sugar. Etc
This project addresses the use of the PLC system in the stages of the sugar
industry and in the Diesel Power Station (DPS) which is supplying the sugar
:factory by power source in terms of
Move the crop of sugar cane to the factory, where the process of sugar
cutting is the starting stage to prepare it for the grinding process which is
called (Extraction) and then moves to the stage of hygiene through the
removal by (Evaporation) followed by a process of Crystallization through
boiling, and the last stage is the purification of sugar (Refining) in order to
.be ready for consumer use
PLC controlled all these stages, the start of the process of transfer and
cutting and grinding sugar, controlling the size of the pieces and mills speed
and Synchronization, the temperature degree of boilers by sensors, the
amount of water added through the valve, as well as generating alarms in
case of emergency. In the case of The DPS, PLC controlled the speed of the
engines as well as their starting and stopping, beside controlled the active
.and reactive power
