Voltage correction factors for air-insulated transmission lines operating in high-Altitude regions to limit corona activity: a review
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-07-21)
Article
Accés obertNowadays there are several transmission lines projected to be operating in high-altitude regions. It is well known that the installation altitude has an impact on the dielectric behavior of air-insulated systems. As a ... -
Remote power control injection of grid-connected power converters based on virtual flux
(2018-02-26)
Article
Accés obertRenewable Energy Source (RES)-based power plants need to control the active and reactive power at the Point of Common Connection (PCC) with the grid, in order to comply with the requirements of the Transmission System ... -
Enhanced control for improving the operation of grid-connected power converters under faulty and saturated conditions
(2018-02-28)
Article
Accés obertIn renewable energy based systems Grid-Connected Voltage Source Converters (GC-VSC) are used in many applications as grid-feeding converters, which transfer the power coming from the renewable energy sources to the grid. ... -
Impedance modelling and parametric sensitivity of a VSC-HVDC system: New insights on resonances and interactions
(2018-04-01)
Article

Permanent magnet synchronous motor with different rotor structures for traction motor in high speed trains
(2018-06-13)
Article
Accés obertIn this work we proposed to study the use of permanent magnet synchronous motors (PMSM) for railway traction in the high-speed trains (HST) of Renfe Operadora (the Spanish national railway operator). Currently, induction ... -
Development of a behavior maps tool to evaluate drive operational boundaries and optimization assessment of PMa-SynRMs
(Institute of Electrical and Electronics Engineers (IEEE), 2018-04-05)
Article
Accés obertThe trend in traction motor design and optimization is to achieve high torque and power densities, wider speed range and high efficiency within the area defining the most frequent operating points. A fast tool to evaluate ... -
Global sizing optimisation using dual-level response surface method based on mixed-resolution central composite design for permanent magnet synchronous generators
(2018-05-01)
Article
Accés obertThis study presents a global sizing design optimisation of a permanent magnet synchronous generator (PMSG) using the three-dimensional finite-element analysis (3D FEA). To build an optimal parametric model structure, the ... -
Isotopic effects in sub-barrier fusion of Si plus Si systems
(American Physical Society (APS), 2018-04-23)
Article
Accés obertBackground: Recent measurements of fusion cross sections for the 28 Si + 28 Si system revealed a rather unsystematic behavior; i.e., they drop faster near the barrier than at lower energies. This was tentatively ... -
Short circuit analysis of an offshore AC network having multiple grid forming VSC-HVDC links
(2018-11-01)
Article
Accés restringit per política de l'editorialThis article presents the short circuit analysis of an offshore AC network which consists of wind power plants interconnected using HVAC cables. The power generated in the offshore AC network is transmitted to several ... -
Analysis of capacitance to ground formulas for different high-voltage electrodes
(2018-01-01)
Article
Accés obertStray capacitance can seriously affect the behavior of high-voltage devices, including voltage dividers, insulator strings, modular power supplies, or measuring instruments, among others. Therefore its effects must be ...
