5.1.8 Training Simulators<br />
Training Simulators are used to<br />
provide realistic operator training<br />
in a realistic plant training<br />
environment. Training simulators<br />
uses the actual control <strong>and</strong> safety<br />
applications of the plant, running in<br />
operator stations. Plant models<br />
simulate the feedback from the<br />
plant in real time or fast/slow<br />
motion. The training simulator<br />
applications include functions for<br />
backup <strong>and</strong> reload including<br />
recreation of historical information <strong>and</strong> snapshots. Offsite training facilities are often<br />
connected (read only) to the live plant to give information from the real operating<br />
situation.<br />
5.2 Power generation <strong>and</strong> distribution<br />
Power can be provided from mains power or from local diesel generator sets. Large<br />
facilities have great power dem<strong>and</strong>s, from 30 MW <strong>and</strong> upwards to several hundred<br />
MW. There is a tendency to generate electric power centrally <strong>and</strong> use electric drives<br />
for large equipment rather than multiple <strong>gas</strong> turbines, as this decreases maintenance<br />
<strong>and</strong> increases uptime.<br />
The power generation system on a large<br />
facility is usually several <strong>gas</strong> turbines diving<br />
electric generators, 20-40 MW each. If<br />
exhaust heat is not needed in the main process,<br />
it can be used to drive exhaust steam turbines<br />
(so called dual cycle) for additional efficiency.<br />
Voltage levels for High, Medium <strong>and</strong> Low<br />
voltage distribution boards are 13- 130kV, 2-8<br />
kV <strong>and</strong> 300-600 V respectively. Power is<br />
generated <strong>and</strong> exchanged with mains or other<br />
facilities on the HV distribution board. Relays<br />
