Modelado y estudio del líder descendente negarivo en una descarga eléctrica atmosférica y su influencia en la localización del punto de impacto del rayo
(Universitat Politècnica de Catalunya, 2012-07-17)
Tesi
Accés obertIn lightning protection techniques a basic aspect is the identification of the impact point possible, which is determined by the evolution of the initial phase of the lightning, known as the stepped leader, the ground ... -
Multiple second order generalized integrators for harmonic synchronization of power converters
(2009)
Text en actes de congrés
Accés obertThis paper presents a new frequency-adaptive synchronization method for grid-connected power converters which allows estimating not only the positive- and negativesequence components of the power signal at the ... -
Phase stability enhancement in big power networks using renewable generation units controlled by SPC
(2017)
Text en actes de congrés
Accés restringit per política de l'editorialHigh penetration of Renewable Generation Units (RGU), has led to that the interaction of this newfound participators in power network with conventional units be more critical challenges for network operators. Effect on the ... -
Registration of X-rays at 2500 m altitude in association with lightning flashes and thunderstorms
(2014)
Article
Accés obertElectric fields and high-energy radiation of natural lightning measured at close range from a mountaintop tower are discussed. In none of the 12 negative cloud-to-ground upward flashes were X-rays observed. Also no energetic ... -
