training facilities are often connected (read only) <strong>to</strong> the live plant <strong>to</strong> provide<br />
information from the real operating situation.<br />
8.3 Power generation, distribution <strong>and</strong> drives<br />
Power can be provided from mains power,<br />
local <strong>gas</strong> turbines or diesel genera<strong>to</strong>r sets.<br />
Large facilities have high power dem<strong>and</strong>s,<br />
from 30 MW up <strong>to</strong> several hundred MW.<br />
There is a tendency <strong>to</strong> generate electric<br />
power centrally <strong>and</strong> use electric drives for<br />
large equipment rather than multiple <strong>gas</strong><br />
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<br />
driving electric genera<strong>to</strong>rs, 20-40 MW<br />
each. Exhaust heat is often needed in the<br />
main process.<br />
