Just to demonstrate grid frequency variation in the greek
network (which is also synchronized with Bulgarian,
Albanian etc utilities), I uploaded a GIF file which is
actual frequency measurements for the period 16 to 20
December 2000 (sorry, the date does not show onthe graph
after I changed from Office 97 to Office 2000).

I uploaded the file to my web site:

http://www.qsl.net/sv1xv/pics/grid.gif

as QTH.NET does not accept e-mail attachments.

I did these measurements for a client who wanted to
install a grid-connected 50 kW photovoltaic generator
and had to pass this info to the manufacturer of the 
DC/AC inverters.

It is possible that in other parts of the world the
frequency is regulated better!
