Multisource partial discharge detection method and device of transformer substation based on space characteristic parameters

ActiveCN102645621AObtain and locate discharge conditionsConfirm accuracyTesting dielectric strengthFeature vectorTime domain
The invention discloses a multisource partial discharge detection method and device of a transformer substation based on space characteristic parameters. The method comprises the following steps of: collecting an ultra-high-frequency signal received by a UHF (Ultra-High Frequency) antenna in pre-set time; obtaining a segment group of a pulse waveform of the ultra-high-frequency signal from the UHF antenna to form a waveform segment group sequence; calculating a time delay of each antenna according to the waveform segment group sequence, calculating a space characteristic vector to form a sequence and carrying out fuzzy clustering analysis on a space characteristic vector sequence; comparing a characteristic of each classified pulse waveform in a result of the clustering analysis with a characteristic of a pre-set ultra-high-frequency pulse waveform; and determining the type of the pulse waveform. With the adoption of the invention, ultra-high-frequency discharge signals are clustered by using a fuzzy clustering method through that the characteristics of the ultra-high-frequency discharge signals generated based on different discharge power supplies in time domains and frequencies are different, so as to separate the partial discharge UHF signals generated by the different discharge power supplies.
