.OpenIPSL.Electrical.ThreePhase

Information

This package contains three-phase models that can be used to create systems where unbalance plays an important role. Distribution and sub-transmission systems are candidates.

Three-phase systems can be easily connected to equivalent positive-sequence systems by using hybrid positive-sequence/three-phase devices. These models are called MonoTri and are usually represented as a pi-equivalent model. Transformers and power lines have their MonoTri representation in this package.

In addition, multi-phase bus, bank and load models are also available here. The modelling of such devices is based, mainly, on the following works:

• A hybrid three-phase single-phase power flow formulation, by J.M.T. Marinho, and G.N. Taranto, and
• Computer modelling of electrical power systems, by J. Arrillaga, C.P. Arnold, and B.J. Harker.
