Harmonance Suppression Method of Weak Current Cable in Intelligent Building under Strong Current Pulse
When weak wire cables in intelligent buildings resonate,there is a significant loss in transmission,such as signal attenuation and increased interference,increasing the difficulty in suppressing resonance in weak power cables.To address this issue,this paper proposed a simulation for suppressing the resonance of weak wire cables in intelligent buildings under high current pulse environment.Firstly,a distributed parameter model was used to analyze the resonance of weak wire cables in intelligent buildings,followed by the calculation of the loss of weak wire cables.Next,a coupling model between high current pulse electromagnetic field and weak wire cables was constructed.More-over,the capacitor condition of the electromagnetic field on the cable transmission was obtained through the charge scattering field term.Finally,the wide-frequency domain phase compensation method was adopted to calculate the phase compensation,thereby achieving resonance suppression.Experiment results prove that the proposed method can effectively suppress the resonance of weak wire cables in intelligent buildings.Meanwhile,the total waveform distortion rate stays below 0.05%.Therefore,this method can improve the power quality and ensure the normal and stable operation of equipment.
