RESUMO:
Traditionally, the main protection used in low voltage power systems, as distribution systems, is overcurrent protection due to its simplicity and low cost. However, in these recent years the number of distributed generation connected in the system has been
growing, which change the complexity of the system and require a directional module to complement the diagnostic about the fault. Therefore, in this master work is proposed a directional module based on discrete wavelet transform. This tool could recreate
the classic directional protection using just current and voltage scaling coefficients (low frequency), which minimize some drawbacks by using discrete Fourier transform. In addition, the scaling and wavelet coefficients energies are used as directional protection
activators, which makes the fault detection faster and hence the directional trip faster. The proposed method were tested by using the IEEE 30 bus system test and its real-time validation were implemented using a digital signal processor.
