[cdn-nucl-l] Re:RE: Tilting at Windmills (Franta, Jaroslav)
I wish to take issue with one point: Jaroslav said"
"... so there would be no problem in providing a reliable source of
standby power to back up the 100MW of wind committed in the
last 18 months."
In this particualr case this may in fact be true: the power available
is some 2,700 Mw - 100Mw is a small fraction of this. However, in
general one can NOT depend on anything-fired thermal to "back up" wind
or solar or whatever. It is for a simple reason: one soes NOT turn on
a large thermal power plant by simply throwing a switch - it is not a
small backup generator.
Bringing a large power plant on line can take days. And most
tirbine/alternators must be kept spinning to prevent the axle from
taking on a sag, which would destroy the critical clearances in both
the turbine and the alternator.
They are not meant to be turned off, except very rarely for
They are NOT "Back-up" anything - they are the base power suppliers
Even thinking of them in terms of "back-up" is dangerous.
