Resumo:
An environment for real-time simulation of electromagnetic transients in power
systems processed in FPGA is presented in this dissertation. The process of constructing
this structure initially involved the use of offline simulation environments for the
implementation and prior evaluation of routines that are to be transcribed into hardware
description language. Then, the modules describing the electric components models
were implemented, as well as those describing mechanisms for control of simulation
and data transfer to external platforms to the device. A mechanism of communication
among multiple devices was also implemented in order to segment the simulation,
which is processed in more than one FPGA board. The real-time simulation
environment was evaluated by comparing simulations of the implemented models and
an IEEE test system with simulations implemented offline. The results indicated that the
simulation environment is a viable and applicable alternative in terms of accuracy of the
results and the processing capacity in smaller calculation steps that other real time
simulators that do not have native features for such, and depending of tools developed
with devices FPGA.
