Due to the considerable progress in computer techniques, many practical problems of current importance can now be resolved. Implementation of cluster systems and SMP computers, using the parallel programming makes it possible to set and solve the problem of creation of real-time electric system simulators.
A digital electromagnetic model of an electric system is needed for the following purposes:
1. To perform computational experiments when

• designing electric networks for electric power transmission;
• choosing basic electric equipment and its parameters, choosing overcurrent and overvoltage protection circuits,
• developing operation measures and procedures to ensure proper reliability of supplying power to consumer.

In this case the numerical electromagnetic model of the electric network operates as a part of Designer's Automated Module.
2. To perform simulation experiments when

• testing existing electric devices and experimentally studying new ones, including digital relay protection devices and anti-damage automatics,
• designing, testing and implementing SCADA-systems.

In this case the numerical electromagnetic model of the electric network operates as a part of a firmware complex (bench testing unit). Benches make it possible to avoid expensive physical models of the power system and reduce the number of even more expensive actual tests, maintaining high efficiency of the work performed and achieving better reliability and objectivity of the results.
To this line also belongs the use of a digital electromagnetic model for simulation and analysis of the scenarios of emergencies within automated information-controlling systems and simulators.
3. Development of program-organized managing actions within control and automation systems.
Solving the problems listed in point 1 practically does not impose any restrictions on the computation speed, while solving the problems in points 2 and 3 sets tight restrictions on the time of obtaining the solution. The latter problems must be solved in real time, which can be achieved by parallel algorithm and using multiprocessor computers.
