Circuit model of a phase-shifting transformer for analog power flow emulation

This paper focuses on the development of a phase shifting transformer model designed to be utilized in analog simulation (emulation). Simulation of power systems is necessary for both operation and planning and depends on suitable models of the components in the system. Analog computation as a technology for the analysis of large scale power systems represents a viable alternative to traditional digital methods as it provides certain advantages, such as speed and parallelism. Prior research in this field has modeled generators, loads and transmission lines. 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 circuit model is constructed and verified via software simulation using Analog Behavioral Models (ABMs) in PSpice and compared with industrial grade numerical simulator for validation.
