TL;DR: In this article, it is pointed out that very fast electromagnetic transients caused by switching operations in gas insulated substations (GIS) cannot be calculated if conventional techniques of modeling and simulation are used, and the selection and adjustment of the most suitable models as well as determinations of their limitations in digital simulations of very fast transients in GIS are investigated.
Abstract: It is pointed out that very fast electromagnetic transients caused by switching operations in gas insulated substations (GIS) cannot be calculated if conventional techniques of modeling and simulation are used. The selection and adjustment of the most suitable models as well as determinations of their limitations in digital simulations of very fast transients in GIS are investigated. Results obtained from very extensive field tests and from digital simulations for different types of GIS have been used for the development of more accurate models for GIS components and GIS as a whole. A comparison between field test and calculation results permits the development of a model which takes into account the most decisive physical phenomena inherent in the very fast transients in the GIS. This is a prerequisite for designing and manufacturing power system components as well as for control and protection of the system. >

TL;DR: To explore and simulate accurately the influence of rain, cloud, gaseous absorption and multipath fading on the air-ground link, the mathematical and simulation models for the rain attenuation, cloud attenuated, gasesous absorption attenuation and Ricean fading were implemented.
Abstract: Development in Near Space Vehicle communication has increased the need for simulation to test and analyze protocols for this emerging technology. Network simulators lack a realistic near space path loss and fading module which would allow having accurate simulation. To explore and simulate accurately the influence of rain, cloud, gaseous absorption and multipath fading on the air-ground link, the mathematical and simulation models for the rain attenuation, cloud attenuation, gaseous absorption attenuation and Ricean fading were implemented. Moreover, modeling and simulation were done within QualNet. Simulation results quantitatively show the effects of rain attenuation, cloud attenuation, gaseous absorption attenuation and Ricean fading on the performance of packet delivery rate of the High Altitude Platform station (HAPs) air-ground link. Thus, simulation of the air-ground link becomes more accurate and reasonable. Simultaneously, the used simulation platform is also improved by integrating new models.
