The Comparative Analysis of Phase Shifting Transformers

Phase shifting transformers (PSTs) are currently widely used in power systems to control flow. In this manuscript, the results of asymmetrical PST (APST) with in-phase (called controllable PST-ACPST) were compared, allowing both longitudinal and quadrature voltage. The MATLAB simulation model ACPST was built obtain influence selected models for parameters. Then 30A laboratory device laboratory. parameters then adjusted real life model. This allowed verifying computer simulations. Based on model, APST built; given work conditions, PSTs compared. construction always resulted higher output voltage than input one. achieved same transfer lower voltage, which is its main advantage. dependency a result greater angle compared classical APST. also adjusting voltages; therefore, type can be installed places where high flexibility required, especially renewable energy sources penetration.
