In this work, a two-area four-machine system with wind power generation is developed in parallel in bothRMS and EMT environments. The fundamental frequency positive sequence (RMS) model is developed in DIgSILENTPowerFactory and the electromagnetic transient (EMT) model, in PSCAD. Specifically, this paper focuses on the systematicdevelopment of the comparable converter model in both environments. To model the wind farm, a PSCAD EMTvoltage source converter model is reconfigured and simplified to replicate the control of the default PowerFactory convertermodel that is used. The performance of the two models is assessed within a simple system, before integrating the windfarm into the two-area system. The selection of the control parameters is chosen in both models to provide a comparableresponse for a step change to the reference power. The default fault ride through (FRT) control is enabled in PowerFactoryand a FRT control strategy is developed in PSCAD to achieve a realistic response. A three-phase short circuit fault on a paralleltransmission line segment and a 100 MW load step change are independently applied in order to compare the dynamicresponse of both models. The specific limitations of converter modelling in RMS simulations are discussed.
