eMEGAsim is a high-accuracy, multi-processor, fully digital real-time simulator optimized for hardware-in-the-loop applica-tions and evaluation of electro-magnetic transients expected in large power grid and power elec-tronic systems. eMEGAsim is ideal for the real-time simulation of distributed energy generation and distribution systems found in large commercial and military ships, electrical train traction systems and feeding networks and in-land power grid and wind farms.

Combining Opal-RT’s RT-LAB simulation platform, Intel®

Core™2 Quad processors and FPGA technology, eMEGAsim can conduct multi-rate real-time simulation of large power grids. eMEGAsim can also achieve the sub-microsecond time step values required to accurately perform real-time simulation of the growing number of power electronic devices found in today’s 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 efficiency and security of large power systems. It is also ideal for system design, training and research applications.

eMEGAsim is scalable from 4 to 64 computer processors and can simulate increasingly large systems with a high level of accuracy while maintaining real-time performance. Ready-to-use application examples are included, as well as a library of complex power grid and power electronic system components. eMEGAsim is delivered with mathematical solvers optimized for parallel simulation of complete power systems comprised of multi-machines, transmission lines, transformers, complex power electronic loads, and FACTS systems.

FrOM eMtP-rV tO reaL-tIMeeMEGAsim is the ideal real-time simulator for users of the EMTP-RV platform for off-line simulation and analysis of transients in power systems.

EMTP-RV is used by many of the world’s electrical utilities to evaluate system transients expected on transmission lines and other equipment. Until now, large power grid models created using the EMTPWorks one-line diagram GUI could only be simulated in offline mode.

Through its tight integration with Simulink/SimPowerSystems from The MathWorks, as well as Opal-RT’s own powerful algorithmic solvers, eMEGA-sim can be used to conduct real-time and fast simulation of large power grids modeled in the EMTP-RV environment.

eMEGAsim 8-processor modules can be configured as multiple individual simulators to conduct multiple studies simulataneously, or interconnected to create a powerful platform using up to 64 processors for simulating very large power grids at a time step value as low as 20 microseconds.

Such supercomputer performance levels, difficult to achieve with proprietary real-time computer systems, are achieved through eMEGAsim`s use of off-the-shelf computer system configurations including the ALTIX XE supercomputer system, from SGI, an Opal-RT partner.

eMEGAsim real-time computer and IO chassis are typically equipped with two INTEL CORE™2 Quad pro-cessors (resulting in 8 cores per motherboard) with up to three (3) XILINX VIRTEX IIPro user programmable FPGA processors (OP5130 board) and 192 fast IO channels with integrated signal conditioning. Large systems are integrated in 19-inch cubicles with fast communication switches and signal monitoring patch panels.

In addition, eDRIVEsim, eMEGAsim’s companion product line, is optimized to simulate power electronic systems and small power grids using 2 to 8 processor cores.

This means that eMEGAsim can be easily integrated into an EMTP-RV environment to provide real-time simulation capability without the need for operators to learn new interface software.

With eMEGAsim, EMTP-RV models of electromagnetic transient pheno-mena can be simulated in real-time with a maximum sampling frequency of approximately 50 kHz (20 microseconds) yielding excellent results for faster transients up to 400 kHz, which can be evaluated using FPGA processors with a 4 MHz model time step.

eMEGAsim can be used in hard real-time mode for HIL applications and in faster-than-real-time mode to accelerate the simulation of very large systems required to conduct system parameter optimization.

eMEGAsim takes full advantage of fast FPGA technology and INTEL’s latest multi-core processors to provide industry leading real-time simulation performance and accuracy.

During simulation, each Intel core is dedicated to the simulation of individual model subsys-tems. In addition, by directly using the efficient cache subsystem of the Intel® Core™2 Quad processor, eMEGAsim obtains computation efficiencies of greater than 100%. As the number of cores used is doubled, the time step decreases by more than a factor of two. The resulting efficiency enables faster and more accurate simulation of electromagnetic transient pheno-mena and thus greater understanding of the power system under study.

By using Intel®’s multi-core technology, eMEGAsim also benefits from very tightly coupled CPUs to overcome the time latencies experienced in cluster systems delivering significantly faster performance. While high-performance cluster systems can report communication overhead or jitter as long as 10 to 50 microseconds or more, eMEGAsim is able to deliver considerable performance advantages with maximum communication overhead and jitter as low as one microsecond. Such performance permits simulations with time steps below 3 microseconds to achieve very high accuracy when simulating fast transients.

eMEGAsim also enables calculations of very fast transients by using onboard FPGA proces-sors to achieve time step values of less than 250 nanoseconds. This functionality drastically increases the accuracy of 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® Neutrino® real-time operating system, closed-loop testing enables full validation of complex systems and greatly facilitates controller design.

FPGA processors are user programmable with Simulink and Xilinx System Generator graphi-cal modeling tools. Engineers are able to generate executable code directly from high-level block diagrams and do not need expertise in VHDL programming skills
