Generalized Voltage-based State-Space Modelling of Modular Multilevel Converters with Constant Equilibrium in Steady-State [PDF]
, 2017 This paper demonstrates that the sum and difference of the upper and lower arm voltages are suitable variables for deriving a generalized state-space model of an MMC which settles at a constant equilibrium in steady-state operation, while including the ...

High Voltage, Volume 10, Issue 6, Page 1602-1615, December 2025.ABSTRACT Converter transformers are the core components of ultra‐high voltage (UHV) transmission systems. The main cause of faults in converter transformers is irreversible deterioration of oil–pressboard insulation under combined electrical–thermal–mechanical stress over long operating times.

High Voltage, Volume 10, Issue 6, Page 1371-1379, December 2025.ABSTRACT This paper focuses on the energisation of high voltage DC (HVDC) and medium voltage DC (MVDC) insulation systems, referring mainly to cables for both theoretical development and validation testing. Cable system energisation can be frequent during its lifetime, and it can possibly be affected by partial discharges (PD), because of manufacturing,

High Voltage, Volume 10, Issue 6, Page 1437-1450, December 2025.ABSTRACT This study proposes a nondestructive optical imaging‐based three‐dimensional (3D) reconstruction method to analyse electrical tree propagation in polypropylene (PP) cable insulation under mechanical bending. The technique combines focus‐stacked optical imaging with a feature fusion algorithm to segment in‐focus regions across depth layers ...

, 2014 High-voltage direct current (HVDC) is a commonly used technology for long-distance power transmission, due to its low resistive losses and low costs. In this paper, a novel distributed controller for multi-terminal HVDC (MTDC) systems is proposed.

What to expect from a greater geographic dispersion of wind farms? - A risk portfolio approach [PDF]
, 2007 The UK, like many other industrialised countries, is committed to reducing greenhouse gas emissions under the Kyoto Protocol. To achieve this goal the UK is increasingly turning towards wind power as a source of emissions free energy.

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 ...
