Modelling of saturated reactor compensator for system studies

A method of modelling multi-limbed saturated reactors under dynamic and steady-state conditions, allowing for both the electrical interconnection of the windings and the core construction, is presented. A selection of results from a digital computer program based on the simulation are given, illustrating the dynamic response of the reactor model to parameter changes under system energisation. The principle of harmonic series compensators in saturated reactors is described, and the harmonic analysis of the model´s steady-state current waveforms for various loading is discussed.
