Simulação de transitórios eletromagnéticos em tempo real via FPGA.

Abstract

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.
