This paper focusses on how Stator water
cooling system is being carried out using present control
logic, its importance, operation, advantages and
limitations in existing control.One of the ways of taking
away the losses from the windings of any electrical
machines is by direct cooling using water. The optimum
design of large capacity turbo-generator,as a rule
envisages water cooling of stator windings. The
200/210/235 MW generators employ a closed loop
circulation of High quality De-Mineralized water through
the stator windings made of hollow and solid
conductors.To enable software control we introduce
Programmable logic controllers (PLC). Today’s PLC
consumes milli-seconds of time for each I/O scanning. It is
a real-time operating system. They are playing everpopular
and critical roles in modern control systems. By
introducing PLC into SWC System the total control is
made possible with software. Incorporation of HMI and
PC makes end-user to view system activities right through
desktop screen.
