“…The present real-time electric simulator is based on RT LAB real-time, distributed simulation platform; it is optimized to run Simulink in real-time, with efficient fixed-step solvers, on PC Cluster [9]. Based on COTS nonproprietary PC components, RT LAB is a modular realtime simulation platform, for the automatic implementation of system-level, block diagram models, on standard PC's.…”

“…Therefore, subsystems are needed. The user must add a prefix to all the top-level subsystems to allow RT-LAB [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] to manage them. There are 3 types of subsystems.…”

“…It is based on a central principle: the use of widely available, user-friendly, highly competitive commercial products (PC platform, Simulink TM ). The real-time simulator consists of two main tools: a real-time distributed simulation package (RT-LAB) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][19][20][21][22] for the execution of Simulink block diagrams on a PCcluster, and algorithmic toolboxes designed for the fixedtime-step simulation of stiff electric circuits and their controllers. Real-time simulation and Hardware-in-theLoop (HIL) applications [5,7,13,15,20] are increasingly recognized as essential tools for engineering design and especially in power electronics and electrical systems.…”

Nowadays the researchers want to develop their model in real-time environment. Simulation tools have been widely used for the design and improvement of electrical systems since the mid twentieth century. The evolution of simulation tools has progressed in step with the evolution of computing technologies. In recent years, computing technologies have improved dramatically in performance and become widely available at a steadily decreasing cost. Consequently, simulation tools have also seen dramatic performance gains and steady cost decreases. Researchers and engineers now have the access to affordable, high performance simulation tools that were previously too cost prohibitive, except for the largest manufacturers. This work has introduced a specific class of digital simulator known as a real-time simulator by answering the questions ''what is real-time simulation'', ''why is it needed'' and ''How it works''. The latest trend in real-time simulation consists of exporting simulation models to FPGA. In this article, the Steps involved for implementation of a model from MATLAB to REAL-TIME are provided in detail.

“…HydroQuebec has since ceased commercializing their Hypersim product. Attempts have been made by a number of universities and research organisations to develop fully digital real-time simulators using low-cost standard PC technology, in an effort to eliminate the high costs associated with the use of high-end supercomputers [4]. Such development has been very difficult to achieve due to the lack of fast, low-cost inter-computer communication links.…”

This paper describes a versatile, multi-domain, large power grid real-time digital simulator. Its ability to conduct multiple tests for protection coordination studies is described. A large grid model built using the EMTP-RV software and simulated in real-time using the eMEGAsim platform's EMTP-RT software tool is described. A discussion and comparisons on the different solvers offered with both simulation environments are made. Comparisons between offline and Real-Time simulations are made using superimposed fault condition waveforms. Finally, multiple random tests are performed on the featured power system model and analyzed using the eMEGAsim simulator's software package.

“…The WR advantage in simulation time due to latency exploitation is lost if the solution does not converge quickly. But, more importantly, since the solution time per time step depends on the number of iterations and this number can change from solution point to solution point, the technique is not suited for real time [8]- [10] or multi-computer simulation clusters [11], [12] where the hardware needs to be synchronized at evenly spaced time steps with a global clock. In this paper, circuit latency is exploited using a direct simultaneous solution for the branch currents linking the subsystems.…”

Multirate simulation of electric networks exhibiting a wide variety of time constants decreases the simulation runtimes by exploiting the property of circuit latency. The fundamental idea is to use different integration steps for different network subsystems, according to the requirements of accuracy of each subsystem. Programs that exploit circuit latency are usually based on relaxation methods that require iterations among the different subsystems of the original networks. These methods lack the numerical robustness of direct implicit integration methods used in circuit simulators and are not adequate for real-time simulation due to their non-uniform solution times. This paper proposes circuit latency exploitation without iterations making use of the concept of interlinked Multi-Area Thevenin Equivalents (MATE). Results are presented showing the efficiency and accuracy of the method.
