Random Generation of Arbitrary Waveforms for Emulating Three-Phase Systems. IEEE Transactions on Industrial Electronics, 59 (11), 4032-4040.0278-0046https://hdl.handle.net/11441/77150This paper describes an apparatus for generating a signal representative of steady-state and transient disturbances in three-phase waveforms of an ac electrical system as described in IEEE Std 1159-09. It can be configured as a synthesizer of randomly distorted signals for different applications: for testing the effects of disturbed grid on equipment and to generate patterns of electrical disturbances for the training of artificial neural networks, which are used for measuring power quality tasks. For the first purpose, voltage and current amplifiers are added in the output stage, which allows the generation of disturbed signals at grid level.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/AC generatorsArtificial neural network (ANN)Load modelingPower hardware in the loop (PHIL)Power quality (PQ)Power system simulationSignal synthesisTest equipmentinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1109/TIE.2011.2174532
