UMEC Transformer Model for the Real Time Digital Simulator

This paper introduces the UMEC (Unified Magnetic Equivalent Circuit) transformer model recently implemented for the RTDS Simulator. The UMEC transformer algorithm was reorganized to meet the requirement of real time simulation. The detailed implementation and optimization of the algorithm are described. Validation of the model is also presented. The validation was conducted by comparing the real time output with that of analytical calculations and off-line simulation results from EMTDCTM.
