چکیده

The anti-islanding protection of distributed generators is typically performed by conventional schemes that monitor the magnitude and frequency voltage signals. However, one main issues to setting these identify differentiate variations an islanding event from other disturbances may occur along system, such as sag or swell. By using Artificial Neural Network (ANN) based algorithm, it possible recognize existent patterns on generator waveform, which makes obtain accurate response about events. ANN training process involves important definition architecture, data window length, sampling rate, selection a representative set for analyzed power grid. In this context, paper discusses fundamental aspects used detection photovoltaic generators.
