Mechanism of Quasi‐Power‐Frequency Resonant Overvoltage Triggered by Multiple Lightning Strikes in High‐Voltage Alternating Current Systems Equipped With Shunt Reactor

High Voltage, EarlyView.
ABSTRACT This paper investigates the generation mechanism of quasi‐power‐frequency resonant overvoltage triggered by multiple lightning strikes in high‐voltage alternating current (HVAC) systems equipped with shunt reactors. Based on field measurements from a 500 kV AC system, equivalent and simplified circuit models have been established to analyse ...

Goniothalamin as a Styryl‐Lactone Toxicophore in Cancer Models: Electrophile‐Driven DNA Damage, Reactive Oxygen Species–Endoplasmic Reticulum Stress Signaling and Detoxification‐Relevant Safety Considerations

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
Goniothalamin (GTN) exerts anticancer effects by promoting reactive oxygen species (ROS) generation, glutathione (GSH) depletion, DNA damage, endoplasmic reticulum (ER) stress, and mitochondrial dysfunction. These interconnected events trigger apoptosis, necroptosis, anoikis, and autophagy, while modulating mitogen‐activated protein kinase (MAPK ...

Defense Algorithm Based on Reinforcement Learning and Digital Twin for Distribution Protection Devices Adversarial Samples

Engineering Reports, Volume 8, Issue 6, June 2026.
Power system protection devices are vulnerable to adversarial samples. We propose a digital twin and reinforcement learning framework. It trains a virtual model within safe operational boundaries, reducing the false operation rate to below 3.5%. The model's inference delay is under 10 ms, meeting real‐time protection requirements.

Busbar Fault Direction Identification Using Sequences of Displacement Vectors

Engineering Reports, Volume 8, Issue 2, February 2026.
In this paper, a novel busbar fault direction identification scheme is presented. The proposed scheme is based on sequences of displacement vectors. The proposed algorithm is fast and simple enough to be embedded in a differential relay to assist the percentage‐restraint differential algorithm.

基于ATP-EMTP仿真软件的输电线路雷击跳闸率多因素对比分析研究

Dianci bileiqi, 2019
通过电磁暂态仿真程序ATP-EMTP,建立了110 kV输电线路的雷击分析模型,主要包括:雷电流模型、杆塔模型、绝缘子串闪络模型等,该模型可以真实地反映雷电流在杆塔上的传播过程。然后分别利用规程法和ATP仿真法进行了计算与分析,得到线路在不同条件下的跳闸率;分析了杆塔高度、冲击接地电阻以及线路绝缘水平等因素对雷击跳闸率的影响。结果表明:在同等情况下,ATP-EMTP仿真计算的反击跳闸率略高于规程法的计算值;随着杆塔高度的降低、杆塔冲击接地电阻的减小、绝缘强度的增强,反击跳闸率减小。

Lightning Performance Evaluation of Italian 150 kV Sub-Transmission Lines

Energies, 2020
A significant majority of overhead transmission lines’ (OHLs) outages is due to backflashovers caused by direct lightning strikes: the realistic assessment of the lightning performance is thus an important task.
