In this paper, a new and efficient VFT park model suitable for stability and dynamic analyses of asynchronous links is presented. This model allows the simulation of multi-unit VFTs operated in parallel in order to increase the power transfer between two electric power systems. The backbone of the VFT model relies on a reduced order model of a wound-rotor induction machine. The computation of the...
A VFT park model suitable for stability analyses of asynchronous links is presented in this work. This model allows the simulation of multi-unit VFTs operated in parallel in order to increase the power transfer between two electric power systems. The backbone of the VFT model relies on a reduced order model of a wound-rotor induction machine. The VFT control system includes power and speed regulators...
This paper presents a powerful analysis tool based on the Poincareacute map method and an implicit integration algorithm to compute periodic steady-state solutions of a variable frequency transformer, suitable for harmonic-oriented studies. Whilst the computation of the periodic steady-state solution is achieved with an acceleration procedure based on the Poincareacute map and a Newton method, an...
