Inverter modelling techniques for protection studies [PDF]
2012 3rd IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2012 Traditional fault calculation techniques are not capable of accurately modelling the short-circuit behaviour of inverter interfaced distributed generation (IIDG). As the share of IIDG continues to rise, more accurate fault simulations are required. This paper gives an overview of fault calculation techniques described in literature.

Inverted hierarchy models of neutrino masses [PDF]
Nuclear Physics B, 2001 We study models of neutrino masses which naturally give rise to an inverted mass hierarchy and bi-maximal mixing. The models are based on the see-saw mechanism with three right-handed neutrinos, which generates a single mass term of the form $ _e( _ + _ )$ corresponding to two degenerate neutrinos $ _e$ and $ _ + _ $, and one massless ...
