eMEGAsim, by Opal-RT, is a distributed, parallel computing solution for real-time simulation of electromagnetic transients in power systems. Based on Intel processors, eMEGAsim combines RT-LAB, and FPGA technology to obtain simulation time steps below 250ns, a requirement for simulating the very fast electromagnetic transients encountered in power systems. eMEGAsim is designed for real-time simulation, integration and hardware-in-the-loop testing of protection devices and power electronic controllers to ensure the security of large power systems. It is also used for system design, training and research.
eMEGAsim is an integrated software and hardware system designed for computation-intensive applications. At its core is RT-LAB software and off-the-shelf components including Supermicro motherboards equipped with dual Intel(R) Core(TM)2 Quad processors and Xilinx Virtex(TM) FPGA. eMEGAsim executes on Intel compatible hardware including Opal-RT systems and soon, on the new SGI(R) Altix(R) XE. eMEGAsim is scalable from 8 to 64 processor cores and can simulate increasingly large systems while maintaining real-time performance. It is adapted for real-time simulation of complete power systems installed in aircrafts, spacecrafts, shipboards and trains as well as in-land large power grid systems and wind farms.
eMEGAsim enables calculations of very fast transients directly on the FPGA chip, with time steps of less than 250ns. This functionality drastically increases the accuracy the simulation of complex power electronics devices found in most power systems.
FPGA-based Inputs and Outputs (I/O) enable high-speed, direct connection with external equipment for hard real-time, hardware-in-the-loop testing. Executed under the QNX(R) Neutrino(R) real-time operating system, closed-loop testing enables full validation of complex systems and greatly facilitates controller design.
The FPGA processor is user programmable with Simulink, and Xilinx System Generator graphical modeling tools. Engineers are able to generate executable code directly from high-level block diagrams and do not need expertise in VHDL programming skills. Electrical system models are automatically generated from electrical schematics using SimPowerSystem.
