Turbine Load Controller Models

Hello, I want to get some information about LCFB1 model. FYI, PSS/E version in my computer is 34 version.

I want to upload the block diagram of LCFB1 and Tables(VARs, ICON, CON) but I don't know how to do. Please refer to the manual.

My questions are..

  1. Where is Pref0(VARs L+2) of the table on the block diagram? As far as I remember, Pmwset is supervisory controller but it is not Pref0 on this block diagram I think.

  2. I want to set their Pgen of raw file to the power reference of LCFB1 model. Because some model references were set to Pmax. How can I do that?

  3. Can I simulate the secondary frequency response through changing the var L+2 Pref0 in this model?

Pmwset is the supervisory control input and is stored in the lcref array. Pref0 is probably the initial power reference.

Now as you update the lcref to a set point calculated by the agc, the supervisory control is implemented. Some governor models like ggov1 has the pmwset stored in a variable, like var(l+6) in case of ggov1, other governor models dont. So you have to use the lcfb1 in conjunction with your governor model, say like ieeeg1, pidgov, you can make use of this load controller model to take advantage of this functionality.
