Two Winding Transformer Equivalent Model of Three Winding Transformers for MATPOWER
DEStech Transactions on Engineering and Technology Research, 2020 MATPOWER is one of wide used authoriterative open source software of power flow calculation in the world. However, it only provides a model of the two-winding transformer thus limiting its application in power system with a three-winding transformer which is very popular in the power system.

Learning to optimise wind farms with graph transformers
Applied Energy, 2023 This work proposes a novel data-driven model capable of providing accurate predictions for the power generation of all wind turbines in wind farms of arbitrary layout, yaw angle configurations and wind conditions. The proposed model functions by encoding a wind farm into a fully-connected graph and processing the graph representation through a graph ...

Characterization of Power Transformer Electromagnetic Forces Affected by Winding Faults [PDF]
Journal of Operation and Automation in Power Engineering, 2018 Electromagnetic forces in power transformer windings are produced by interaction between the leakage fluxes and current passing them. Since the leakage flux distribution along the windings height is in two axial and radial directions, so the ...
