Reconfigurable Phase Shifting Transformer for Analog Computation

Abstract

This paper focuses on the development of a phase shifting transformer model designed for a previously proposed method of analog power flow computation. Prior research in this field has modeled generators, loads and transmission lines. Accurate analog models of power system components are required in order to realize an analog computation engine for power systems. Analog computation is an area of continued interest and has certain advantages over traditional digital computation. Among the advantages are physically realizable solutions and significantly faster computation times. The transformer model proposed here provides a more accurate depiction of the network and captures the behavior of phase shifting transformers. The transformer is modeled in analog form. The model is constructed and verified via software simulation.
