The omission and false alarm of partial discharge insulation defect of gas insulated switchgear (GIS) seriously affect the safe and stable operation of GIS. Considering that GIS may be affected by various vibration factors in actual operation, this paper builds an intermittent discharge test platform for shock and vibration superimposed multi-source detection, and carries out experimental research on the characteristics of intermittent discharge under different vibration conditions for common internal typical insulation defects in GIS. The study found: The vibration state has a certain influence on the intermittent discharge of defects in GIS equipment, and the intermittent discharge law in the non-vibration state is consistent with that in the normal operation vibration. However, the insulation strength of metal particle defects decreases greatly under shock vibration, and with the continuous discharge process, the discharge interval develops from seconds to milliseconds, from intermittent discharge to continuous discharge. The research results are of great significance for broadening the understanding of intermittent discharge characteristics and promoting the field GIS discharge defect detection.

University administrations are always in need for tools to optimize their operation decreasing operational costs and ensuring a good learning experience for students. Advising and course offering are two main tasks that require knowledge in the field and expertise. The tasks need also data and its related analytics. This paper presents an innovative advising tool based on data mining leveraging from electrical power concepts. The tool uses Python and Excel to automate advising sheets and electrical power engineering by applying simultaneity and the factor of utilization to students records and courses to predict future course enrollment with a RMSE=0.75. The research proposed is unique since it helps administration and advisors. With the reduction of resources and disruption of the classical educational system new tools should be elaborated to reduce costs and secure on time graduation of students. © 2025 IEEE.

With the rapid development of new power systems, abnormal problems in electric energy metering devices are becoming increasingly complex. Especially in the environment of multi-source information interaction, higher accuracy and real-time requirements are put forward for the evaluation of abnormal handling. To solve this problem, this paper proposes an abnormal handling evaluation model for electric energy metering devices based on multi-source information fusion. Firstly, data preprocessing and feature selection techniques are used to ensure the integrity and consistency of multidimensional information data. Secondly, a comprehensive evaluation index system based on Analytic Hierarchy Process (AHP) and dynamic optimization of weights is designed to quantify the treatment effect. Then, based on the Transformer network, the temporal dynamic characteristics of the abnormal treatment process are deeply modeled to capture the complex dependencies and interactive characteristics of multidimensional data. Finally, through multimodal data fusion technology, the equipment operating status, environmental parameters and historical records are integrated to achieve a highly robust and adaptable evaluation model. Experimental results show that the prediction accuracy of the Transformer-based model reaches 94.7%, which is significantly better than random forest (89.3%) and support vector machine (SVM) (85.6%);in terms of time response performance, the processing efficiency is more than 50% higher than that of random forest;in the robustness evaluation under noise interference conditions, the accuracy decrease is the smallest and significantly better than the comparison model. The research results have verified the application value of the model proposed in this paper in complex power grid scenarios, which can provide efficient and scientific support for new power systems.

In order to improve the power supply reliability of the distribution network and build a digital distribution network, power supply companies in most provinces have carried out the construction of distribution automation system. The feeder terminal unit(FTU) has relay protection function. The incorrect operation of breaker sometimes caused by the wrong configuration of FTU parameters. The paper analyzes a distribution network failure involving the incorrect operation of the FTU relay protection. Firstly, the process of distribution network fault is introduced. Then, the paper analyzes the results of the accuracy test, protection value analysis, SOE analysis, and device disassembly analysis of the FTU. Finally, the paper provides a detailed analysis of the fault result and proposes rectification suggestions. Through the fault analysis, the paper aims to optimize the parameter configuration of FTU relay protection and improves the reliability of distribution network. © 2024 SPIE.

The growing adoption of renewable energy primary plants has been seen globally. South Africa has seen a significant development in utility-scale photovoltaic (PV) farms in recent years due to the alleviated regulations stipulated in the latest Electricity Regulation Amendment Act. Connecting the PV plants to the power grid has also undergone a technical evolution by incorporating modern embedded computers known as Intelligent Electronic Devices (IEDs). The International Electrotechnical Committee (IEC) 61850 standard defines a suite of protocols used in modern power systems. This study compares the IEC 61850 Manufacturing Messaging Specification (MMS) with the well-known MODBUS protocol. The comparison is achieved by simulating a solar farm's power Plant Controller (PPC). © 2025 IEEE.

In this paper, the trajectory tracking problem for underactuated Autonomous underwater vehicles (AUVs) is investigated. First, a nonlinear 4-DOF AUV model is adopted, considering the unknown parameters and external distances. Two control objectives and corresponding error dynamics are established according to different tracking errors. To achieve accurate AUV tracking control, an adaptive robust control strategy is proposed, combining the backstepping control ideology. This controller could adaptively estimate uncertain model parameters and disturbances recursively and compensate for the estimation errors robustly. Theoretical analysis demonstrates that the proposed control scheme can ensure system stability, enhance the transient response, and give great trajectory tracking performance, which is validated again by the numerical simulations.

Developments in microprocessors based digital relaying have led to the digitalization of power substations. In the following years, continuous advances in digitalization and use of IEC61850 based communications technologies in the digital protection systems have led to the developments of Intelligent Electronic Devices (IED) and their widespread use. IEC61850 protocol has enabled IEDs produced by different vendors to work together. This interoperability provides interaction among to protection systems and control systems, and the necessary data communications during the performance of these systems. After all these developments, the idea of full automation of power networks, instead of digital substation, has emerged. This paper includes the advances in IEC61850 based substation automation, centralized protection and control based substation automation, and also discusses possible future developments in the related area. © 2024 IEEE.
