Stability analysis of the CCS power plant769
Abstract
This work shows the simulations performed using EMTP before and after tuning the PSS of the Coca Codo Sinclair hydro power plant (1500 MW) of the National Interconnected System of Ecuador. Each machin... see moree in the plant is modeled and its control systems (AVR and PSS) are represented by models created by the user and by library models. The results obtained are compared with real signals taken by the Wide Area Monitoring Systems.
In addition, the analyzes performed are shown, from a point of view of the transient stability of the plant, to determine the adjustment of the single-phase reclosing dead time of the San Rafael – El Inga transmission line, at 500 kV, taking into account the secondary arc model of the EMTP library.

Impact of Renewables on System Protection768
Abstract
The presentation will describe how EMTP with its wind turbine model library, as well as its relay model library are being used at EPRI research projects to perform case studies for EPRI member utiliti... see morees.
The integration of inverter based resources (IBRs) into power systems introduces several technical challenges. One major challenge is the impact on system protection, resulting from the complex fault response characteristics of IBRs which are interfaced with the grid through power electronics and do not behave similar to conventional synchronous generators. EPRI is investigating the performance of legacy protection schemes in systems with high levels of IBRs, and potential misoperations which will compromise the grid reliability.
