Study on the Numerical Simulation of Coupling Interference Law of AC Transmission Lines to Buried Pipelines by ZHAO Yalei, CHEN Wei, CHENG Wei, LAN Wei, WU Xiang, MA Liming

“…In energy public corridors， the similar routing of AC transmission lines and buried pipelines inevitably causes the pipeline to enter the AC interference zone， leading to pipeline AC corrosion， abnormal cathodic protection systems， and posing a threat to pipeline operation safety.To study the coupling interference law of AC transmission lines on buried pipelines， based on the pipeline equivalent circuit and electromagnetic induction theory， a model of AC interference of transmission lines on buried pipelines was established using CDEGS.The AC interference intensity and safety distance under typical transmission line characteristic parameters，pipeline parameters and laying environment parameters were calculated.Results showed that the AC interference voltage on the pipeline was directly proportional to the AC transmission current.When the parallel length between the 3PE pipeline and the transmission line was less than 20 km， the AC interference voltage was directly proportional to the parallel length.When the distance between the pipelines and transmission lines was small，the phase spacing and average height significantly impacted the AC interference voltage.As the distance increased， the AC interference voltage initially increased and then decreased.Based on extensive numerical simulations， a safety distance determination chart and AC interference voltage curve suitable for on-site engineering were proposed， providing a reference for selecting new pipeline routing and protecting existing pipelines from interference， thereby reducing the risk of AC interference on pipelines.…”

Receiver design of sparse Bayesian learning based MIMO-OFDM power line communication system by Xinrong LYU, Youming LI, Yongqing WU, Xiaobo TANG

“…The rich impulsive noise in the power line channel poses a huge challenge to the design of MIMO-OFDM transceiver.To solve this problem, a design scheme that can jointly estimate the channel and impulsive noise was proposed, which exploited the parametric sparsity of the classical multipath model and the sparsity of the time domain impulsive noise.In this scheme, the unknown channel model parameters and the impulsive noise were jointly regarded as a sparse vector.By observing the spatial correlation of MIMO system, a compressed sensing model based on multiple measurement vectors was constructed.The multiple response sparse Bayesian learning theory was introduced to jointly estimate the MIMO channel parameters and impulsive noise.The simulation results show that, compared with the traditional receiver scheme that considers MIMO channel estimation and impulsive noise suppression separately, the receiver proposed has a significant improvement in channel estimation performance and bit error rate performance.…”
