This work proposes a new computer modelling methodology for time domain electromagnetic transient simulations in power systems, where the focus is the dynamic performance analysis of FACTS equipment. The proposed methodology consists in applying the trapezoidal method to network elements modelled with dynamic phasors resulting in companion models. For FACTS equipment models, a linearized companion model is obtained and solved together with the electrical network equations by Newton method. One of the advantages of this new methodology is the integrated time domain simulation and linear analysis for coordinated controller tuning of FACTS equipment. The systematic analysis of multiple operating conditions, obtained from power flow programs, is also possible due to the initialization ability of the dynamic phasor models. The computational implementations were carried out in MATLAB and the results compared with simulations in the PSCAD/EMTDC program focusing in the thyristor-controlled reactors.
