| Summary: | This work presents a new architecture layout to perform real time network simulations
distributed among multiple IBM1-compatible desktop computers. A network simulation
with a PC cluster scheme can successfully cope with the size of growing power
systems and fast transient studies. A powerful product has been developed using off-theshelf
Pentium II 400 Mhz personal workstations with a commercially available real-time
operating system, standard I/O interfaces, a multimachine scheme and the RTNS2 realtime
power system simulation software as core solver. Models based on the standard tool
worldwide for power systems transients simulations, the EMTP program [1],[2], and
improved ones for real time performance assure accurate simulation results. Taking
advantage of the hardware and software characteristic of the designed simulator, fast and
accurate simulations can be executed in a very portable, efficient and economic platform, placing the presented simulator in a better competitive position than expensive TNA's
supercomputer simulator systems.
