The NY ISO posts hourly tie flows for the previous month (and earlier). Th= at would provide an excellent opportunity for calibration. Once field prov= en, such monitoring would be useful. ERCOT tie flows are not generally pos= ted (only very much after the fact), and even for NY, the data is out only = after the month is over. I think there would be great value for this info = just in North America, not to mention other systems.

Martin, Any thoughts on this project?

Greetings Vince! =09During the brief idle moments we have here in the lab, I have been ponde= ring yet another possible project. We have built sensor boards and written= programs to calculate the current flow along High Voltage Direct Current l= ines, the type that form the Western Inter-tie. There are six of these l= ines to the west, i.e. to the WSCC - four between WSCC and MAPP and two be= tween WSCC and SPP. It would seem to me to be valuable to know when there = there power supply differences between these NERC regions and when power wa= s flowing between them. (In this case, directionality is no problem. For = once there is actually something flowing!) Of course if this is useful, th= e project could expand to other inter-regional zones. HVDC lines exist in = the northeast between the large Canadian hydro projects and the metropolita= n cities in New England. Globally, there are several large grids being for= med - one in Scandinavia, one in North Africa, an East Russian/Chinese syst= em and a Russian/Korean/Japanese system. Naturally these have to connect i= nternally with DC lines as there are power frequency, power reliability and= power control differences between each of the generating countries. =09You are the first person that I have told about this. I didn't want to = get anyone, especially my immediate supervisors, excited about a technology= that I wasn't ready to provide. I know that once I say that we could do i= t, the powers that be will want it NOW. If you think that there is a marke= t for this imformation I'll sneak out some weekend and collect a bit of dat= a. The nearest HVDC inter-tie is just north of Dallas so testing it would = only take a day or two. I am currently juggling two running chainsaws, a r= abid dog and three vial of hepatitis so one more item in the mix won't make= much of a difference at this point. If no one needs to info, I'll just pu= t the hardware and software on the shelf. p.s. Gina and I would like to take you out to lunch or dinner soon to a Sa= rdinian restaurant. Let us know when you would be free. ( Your wife is in= vited, of course!)
