This 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.Comisión Interministerial de Ciencia y Tecnología DPI2006-15467-C02-01Comisión Interministerial de Ciencia y Tecnología DPI2006-15467-C02-0
