eMT™ - Electromagnetic Transient
Electromagnetic Transients Program
ETAP eMT provides an accurate and intuitive analysis software based on trusted EMT simulations powered by PSCAD's EMTDC engine. eMT is a simulator of AC power systems, low voltage, power-electronics, high-voltage DC transmission (HVDC), flexible AC transmission systems (FACTS), distribution systems, and complex controllers.
When necessary, ETAP eMT integrates with ETAP's Transient Stability program to offer eMTCoSim™ - CoSimulation of Electromagnetic Transients and Phasors to collectively solve large, complex, and multi-disciplinary system models with higher fidelity.

Learn About Integrating Wind Turbines for FPSO Optimal BESS Sizing using ETAP & PSCAD Co-simulation
The transition towards sustainable energy sources is driving innovative solutions in the offshore oil and gas industry. The presentation delves into the integration of a Wind Turbine Generator (WTG) into an existing Floating Production Storage and Offloading (FPSO) vessel to reduce carbon emissions. The technical and operational challenges of this integration are discussed, including load balancing, intermittency of wind energy, transformer energization, motor starting, protection coordination, and maintaining operational reliability. The study utilizes simulations with tools like HOMERPRO, ETAP, and PSCAD to assess the technical feasibility of integrating the WTG and Battery Energy Storage System (BESS) into the FPSO power system. Various studies, including load flow, short circuit, motor acceleration, transient stability, voltage ride through, harmonic analysis, protection coordination, and transformer energization are conducted to ensure the effectiveness and efficiency of the proposed system. There is great potential for reducing the operational carbon footprint of FPSOs by incorporating renewable energy sources and using software simulations to address the complexities and considerations involved in such integration.
Efficient Design & Analysis with CoSimulation
Co-simulation is the cooperative simulation of a system model through different software packages. Collaborative simulation, as such, spans more physics domains and offers more insight than single-domain engines alone. Therefore, the collective composition of its parts enables multi-domain, multi-physics simulation results. ETAP CoSim™ enables ETAP simulation engines to collaborate and interact. For example, the ETAP Time Domain Power Flow can co-simulate with ETAP Harmonic Analysis to assess harmonics distortion over time. ETAP CoSim platform also enables ETAP and 3rd party tools to co-simulate and solve large, complex, and multi-disciplinary system models—collectively via an efficient API surface. The ability to co-simulate with third-party software extends existing software capabilities into the multi-physics domain and greater situational awareness. This solution presentation will introduce the concepts of co-simulation and the flexible ETAP CoSim platform. The presentation will also highlight commercial use-cases of Phasor and Electromagnetic co-simulation using emtCoSim™ and Controller Hardware-in-the-Loop (CHIL).
