Modelling of distribution level coreless induction furnace for rapid voltage change assessment

This paper proposes a mathematical model for a distribution level, directly fed core-less, induction furnace that can be used for network voltage behavior related studies performed by the network operators. The objective of the model is to represent the dynamic behaviour of the facility when an induction furnace is energized (switched) at the beginning of the melting process. Model development is supported by actual field measurements from PCC to a distribution system. The paper includes a case study and the results indicate that the proposed model offers accurate results for rapid voltage change assessment and it is shown that the model can be successfully used for various load changes and at various voltage levels.
