MMC HVDC Controls for Damping Subsynchronous Interactions With LCC HVDC and Thermal Generator
International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.This paper develops a subsynchronous damping controller (SSDC) on modular multilevel converter (MMC) HVDC with the aim of mitigating three‐way torsional interactions between a line commutated converter (LCC) HVDC, MMC HVDC and a nuclear generator. The test case is based on the French IFA2000 2 GW LCC HVDC and the new 1 GW MMC Eleclink, interacting with

An Efficient Hybrid Islanding Detection Method for Microgrids Using Kalman Filter
Engineering Reports, Volume 7, Issue 12, December 2025.Islanding condition gives rise to several problems in distributed generation networks, including power quality disturbances, equipment damage, interference with grid protection, and danger to the utility crews. To avoid islanding detection failure of the passive section in case of a close matching between islanded generation units and loads, the active

Lightning‐Induced Overvoltage on Overhead Distribution Line via Hybrid MTL‐PEEC Method
High Voltage, Volume 10, Issue 6, Page 1464-1473, December 2025.ABSTRACT Transient simulation are more economical and adaptable means of studying lightning overvoltage for overhead distribution line system compared to experiments. A hybrid multi‐transmission‐line (MTL)‐partial element equivalent circuit (PEEC) method proposed for lightning‐induced electromagnetic pulse (LEMP) simulation is verified using the rocket‐

Development of an Electromagnetic‐Thermal Circuit Model for Single‐Phase Three‐Limb Transformers
High Voltage, Volume 10, Issue 6, Page 1545-1557, December 2025.ABSTRACT Analysing the heat states of transformers under DC bias requires careful consideration of their own structural and material characteristics. Although the 3D finite element method (FEM) is a reliable way of simulating all the details of transformers, it may be time‐consuming or have encountered convergence difficulties due to the complex ...

基于FDTD和EMTP的特高压大跨越线路雷击暂态过程对比分析
Gaoya dianqi, 2019 大跨越线路的杆塔高、档距长,反击闪络风险高,准确分析其雷击暂态过程,对于保证特高压线路的安全运行具有重要意义。文中针对淮南—上海特高压工程南通—苏州段的大跨越输电线路,分别建立了该线路雷击暂态过程的FDTD和EMTP模型,得到了大跨越线路的杆塔横担与塔顶电压、导线电压和绝缘子串过电压,并开展了对比分析,结果表明:采用Hara提出的杆塔多波阻抗模型,EMTP计算得到的横担和塔顶电压远大于FDTD计算结果;若不考虑感应分量,EMTP计算得到的导线电压大于FDTD计算结果 ...
