Abstract ：
Unmanned Aerial Vehicle (UAV) are increasingly utilized in power line inspection work, the 3D path planning for UAV urgently needs to be addressed. Artificial Fish Swarm Algorithm (AFSA) is one of the most common used methods for the 3D path planning of UAVs, but the problems of rapid convergence and susceptibility to less optimal solutions for AFSA needs to be solved. For this reason, a 3D path planning method for power inspection UAVs based on an Improved Artificial Fish Swarm Algorithm (IAFSA) is proposed in this paper. This algorithm references the metropolis criterion of the Simulated Annealing (SA) algorithm and introduces an anti-Metropolis criterion to escape from less optimal solutions. Firstly, a 3D mountainous terrain model is constructed based on the environment where power inspection UAV perform inspection tasks in mountainous areas. Then, the anti-Metropolis criterion is introduced into AFSA to escape from less optimal solutions. Finally, to satisfy the performance constraints of the UAV, a cubic spline interpolation function is used to smooth the path. Comparative simulation experiments with Particle Swarm Optimization (PSO), SA, and AFSA are carried out. The result shows that IAFSA proposed in this paper not only exhibits superior optimization performance in different terrain environments, but also maintains the rapid convergence and optimization accuracy of AFSA. © Beijing Paike Culture Commu.

Abstract ：
The improvement of the transmission capacity of the line of EHV submarine cable has become urgent issues that need to be addressed. The transmission capacity of the EHV submarine cable is mainly determined by the operating temperature of the submarine cable. Therefore, several cooling schemes are compared to analyze their cooling effect on the cable core temperature in this paper. For the water pipe cooling scheme, the cooling effect is the most significant when the velocity of the cooling water is slower than 0.1 m/s, increasing the number of cooling water pipes can effectively reduce the cable core temperature. For the wind cooling scheme, the cooling effect is the most significant when the velocity of the air is slower than 0.1 m/s, and the cooling effect is more significant with the air velocity. For the backfill soil cooling scheme, the cooling effect is more significant with the thermal conductivity of the backfill soil. © Beijing Paike Culture Commu. Co., Ltd 2024.

Abstract ：
As urbanization accelerates, substations have become a part of residential and downtown areas. The low-frequency noise generated by transformers has increasingly become a major source of complaints from neighboring residents. Due to the long wavelength of low-frequency noise, traditional passive noise reduction technology is bulky, expensive and limited in effectiveness. Active noise control (ANC) has gained attention due to its compact size, light weight, low cost, and excellent ability to reduce low-frequency noise. However, the precision of ANC relies on the control algorithm, and conventional least mean square-based algorithms still face challenges such as sluggish convergence, susceptibility to dispersion, and poor stability. In light of the time-varying characteristics of transformer noise, this paper proposes a machine learning-based algorithm for generating inverse noise waveform through time-series forecasting, and this approach aims to achieve rapid and stable noise reduction. The experimental result shows that the algorithm achieves noise reduction effects of 49.67 dB, and the time used for training and prediction is 1.78 s and 1.64 s, which shows a promising solution for transformer noise reduction. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Abstract ：
AC surface flashover is a prevalent insulation fault in gas-insulated equipment. Given the complex dependency of this fault on various factors and the limitations of destructive experimental methods, this paper proposes the use of tree-based machine learning models as an economical and efficient alternative to obtain the flashover voltage. The analysis concentrates on salient features impacting AC surface flashover, such as electroluminescence (EL), water contact angle (WCA), and percentage of silicon atoms (PSA). The extra trees algorithm was employed and optimized by feature selection. The model, utilizing six features—EL, WCA, PSA, Polished status, Ra, and surface resistivity—yielded excellent performance with MAE, MSE, MAPE, and R2 scores of 0.50, 0.37, 1.47%, and 0.93, respectively. The study highlights the potential of tree-based models in providing insights and prediction of surface flashover voltage for the insulation in gas-insulated equipment. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Abstract ：
Polarimetric fiber-optic current-sensing technology is typically employed for measuring high current, as the low Verdet constant of optical fiber makes Faraday rotation not noticeable in low-current measurements and subsequently leads to low current sensitivity. To enhance current sensitivity, a polarimetric method based on a reflective polarization-bias-added (RPBA) structure is presented in this article. First, it is proved by the Jones matrix that current sensitivity would be compromised due to the constant term in the traditional sensing output. Then, the single-axis measurement method is employed to eliminate the constant term using the single-axis working (SAW) circulator. In consideration of the accuracy of subsequent signal decoding, the bias is generated by the RPBA structure to process optical signals between the circulator and the mirror. Next, a decoding algorithm based on parameter optimization is presented to restore the measured current from the photodetector output. Finally, the experimental results show that the current sensitivity of the presented method can be larger than 0.005 V/A under the premise of small measurement error in the vibration-and-temperature test. Compared with the existing polarimetric methods whose current sensitivity tends to be 0.002 V/A, the presented method has better current sensitivity without incurring additional sensor-head turns or optical devices.

Abstract ：
Breakdown voltage of the nitrogen insulation gap can be increased by inserting a polymer barrier to form a hybrid nitrogen-barrier insulation system. In this article, the effect of barrier position on the breakdown voltage of a hybrid insulation system is investigated at different gas pressures. Reducing the distance from the barrier surface to the rod electrode leads to higher breakdown voltages at gas pressures in the range of 0.1-0.25 MPa. Additionally, the breakdown field strengths of the insulation gaps at different gas pressures are studied. When the barrier is placed near the plate electrode, the breakdown field strength shows a linear increase with increasing gas pressure. Furthermore, the breakdown paths in the hybrid insulation systems can be classified into two types. The breakdown voltages of the two path types are close. A prediction model of the breakdown voltages at different pressures based on the breakdown path is proposed. The proposed model is also suitable for hybrid insulation systems with different size barriers. The barrier with lower relative permittivity and higher resistivity tested in this article has a more significant effect on increasing the breakdown voltage. The influences of the barrier surface charge on the electric field and breakdown processes are also discussed.

Abstract ：
Low-current measurement is a challenging task for polarimetric fiber-optic current-sensing (FOCS) systems due to low signal-to-noise ratio (SNR) and sensitivity to current (STC). To tackle the challenges, this article proposes a FOCS approach on bias-added measurement and main-component reconstruction. To enhance STC, the adopted FOCS structure is based on bias-added measurement using a bias-current coil and a single-axis working circulator instead of traditional polarizers. However, the unavoidable noise would decrease the SNR of FOCS output. An algorithm of main-component reconstruction is presented to filter out the noise. The main-component distribution of the FOCS output is analyzed by a feature vector based on the spectral subzones. Using an appropriate threshold, the subzones with prominent features are self-adaptively decomposed to extract the main components by fast matrix decomposition. At last, the main components are adopted to reconstruct the FOCS signal. In comparison with other reflective methods, the experimental data suggest that the STC and SNR of the proposed approach can be increased by 200% and 22%, respectively. The similarity between the expected and reconstructed signals reaches 0.9993 under the premise of a small measurement error.

Abstract ：
Mixing helium and argon as the working gas of cold plasma jet is expected to combine the merits of He plasma jet and Ar plasma jet and has great potential for medical applications. For this reason, the discharge characteristics and reactive species diagnosis of a He + Ar + O-2 plasma jet were studied in this paper. The result shows that the Penning effect between He and Ar is strongest when the volume fraction of Ar in the working gas is 10%, and the plasma jet propagates the longest distance. A low drive voltage and a wide pulse width will weaken the Penning effect between He and Ar, resulting in a decrease in the ionization efficiency of the plasma jet. Gelatin gel was used as the model human tissue, and the effective treatment area of He + Ar + O-2 plasma jet on the model tissue increases with the volume fraction of Ar in the working gas. When the volume fraction of Ar is 50%, the effective treatment area of He + Ar + O-2 plasma jet is 9 times that of He + O-2 plasma jet, and the surface distribution of reactive oxygen species on the model tissue is almost uniform. Moreover, with the increase of volume fraction of Ar, the influence of the change of the plasma jet treatment angle on the surface distribution of reactive oxygen species is significantly weakened, indicating that He + Ar + O-2 plasma jet can precisely control the reactive species dosage on the living tissue for clinical application.

采用适当压力的氮气(N2)作为SF6的替代气体是目前中压环保型开关设备的研究热点.在氮气中引入隔板与其组成气固复合绝缘间隙,能够更好地提升其耐压性能.通过改变隔板水平位置、竖直尺寸、材料及电极结构,得到不同情况下氮气中击穿电压的变化规律.同时将击穿路径分段分析,总结各分段击穿路径的类型及概率,最后结合仿真分析击穿路径上的电场分布变化.结果表明:一定开距范围内氮气中击穿电压随着电极距离的变化相比于空气更加规律;隔板距离高压电极越近及隔板竖直尺寸越大,击穿电压越高;三种材料的隔板中,聚四氟乙烯(PTFE)板对击穿电压的提升效果最弱,云母板对击穿电压的提升效果最好,但其击穿电压受水平位置影响显著.不同水平位置下击穿电压存在差异是因为电场分布情况不同,击穿电压与击穿路径没有太大关系,竖直尺寸是影响击穿路径类型的重要因素.研究结果可以为氮气与聚合物隔板复合绝缘的设计和优化提供参考.

Abstract ：
Traditional polarimetric current-sensing methods contain many optical devices, leading to poor reliability. Also, their sensing output is distorted by massive system noise. To address these issues, this article presents a polarimetric current-sensing method using single-axis polarization encoding (SPE) and a dynamically decoding algorithm (DDA). A single-axis circulator (SAC) and a Faraday rotator mirror (FRM) are used to encode the measured current by light. The SPE only requires these two optical devices in the light-propagation path, enhancing the measurement reliability. The encoding process can significantly suppress the noise by eliminating high-order terms. To correctly restore the current signals, the light intensity is decoded by Jones-matrix analysis and dynamic parameters. Finally, normal currents, fault currents and harmonic currents in grids are used to test the performance of the presented method. The results show that the maximum amplitude error is smaller than 1.3% in a wide range of amplitudes, frequencies, temperatures, and vibrations, and the signal-to-noise ratio and number of devices required in the path are 51.43 dB and 2, respectively (those of the recently published polarimetric method are 1.7%, -4.24 dB, and 5, respectively).
