Network sequence reduction
I'm working on a substation which has four transmission lines coming into it. I have the full grid model with around 2400 buses. Is there anyway in PSSe to get the thevenin equivalent of the four remote buses to my station? I want to model my station only with the 4 remote buses Thevenin Equivalent and the respective 4 lines.
Modeling individual remote buses may be a challenge because it is highly likely that these 4 remote buses contain common connections some buses away from it. If the 4 transmission lines are radial and lead to individual network, then your objective can be achieved by applying EEQV to each network.
Yes, those remote buses are tied to each other through multiple routes and a part of a big grid. So it won't likely be a straightforward seperate Thevenin Equivalent for each bus.
Then you may have to represent the four remote buses to single equivalent network while maintaining four transmission lines.
