Noise resistant discharge detection

Номер: CN116559601A

Partial discharge detection techniques are provided. In one aspect, a method of detecting a partial discharge in a power system having a power electronic converter is provided. A first current signal is captured in response to a first applied voltage. A second current signal is captured in response to a second applied voltage, the second applied voltage being different from the first applied voltage. The first current signal is set as a reference signal. A difference signal is determined based on the second current signal and a reference signal. Whether a partial discharge exists is determined based on the difference signal. The method may iterate, and for each iteration, the reference signal is updated on a scrolling basis to a previously captured current signal measured in response to a previously applied voltage. For each iteration, the applied voltage also increases or decreases.
