Synchronous Condensor (SC) or Hybrid Synchronous Condensor (H-SC) for Steel Making Plants (SMP)

My question now is directly use this kind of VSC (Voltage Source Compensation) in Meltshops.

As anyone knowledge of this kind of systems in SMPs?

Yes, I'm aware of locations where this is not only in use, but in some instances required.

The Ivaco steel mill near Longueuil, Ontario, Canada, which to my understanding employs arc furnaces, uses this to stabilize the voltage on the 230 kV system that supplies it. Whenever the system is for some reason not in service, numerous voltage complaints are received from customers fed by two adjacent transformer stations on the same 230 kV corridor.

Ameristeel in Oshawa, Ontario, also fed at 230 kV, has a flicker compensator that must be in service whenever the mill is in production; this mill was causing so many issues for neighbouring customers that this mandatory stipulation was put in place.

Do you have any data of it? SLD?

Some inputs were gave to me that when EAF is working could cause some vibrations in SCs shafts.

What I red until now is that 3 VSCs systems:

only STATCOM

only SC

Both SC + STATCOM

Are often used in grid voltage stability, mainly in primary substations. For EAF applications only SVC or STATCOM.
 
Welcome to the forums, Jpascp.

Alas, I am now retired, and no longer have any access to information about these schemes; I'm only able to pass along what I remember about them.

I'm not fully informed as to their status worldwide, but from what I've seen, actual synchronous condensers [SC] are becoming quite rare; to my knowledge, for the most part only utilities and governments have the fiscal clout to spend the kind of capital needed to install them and the OM&A budget to run them.

I do recall one transformer station in northwestern Ontario that had [at the time of my retirement a year and a half ago], and presumably still has, both a synchronous condenser and an SVC; I ended up being the person pushing for the development of an operating protocol for how to share the local reactive demands satisfactorily between these two machines, whether boosting or bucking.

Where industries with electric arc furnaces are forced to spend their own money in order to continue operating, they generally acquire their own Static Var Compensator [SVC] and harmonics mitigation schemes so as to satisfy the requirements of the local Authority Having Jurisdiction [AHJ].
 
Have you done an internet search on "electrical flicker compensator compensation"? I just did, and there appeared to be several links to technically expansive articles or pages.

Thanks for your support.

Yes in general in SMPs we use VSCs type SVCs or STATCOMs. I have never seen any SC in it.

It seems that for grid upgrades yes it is used SCs or H-SCs.

I did not find any thing in internet about H-SCs for SMPs.
