Abstract
Fluid models including charge generation and transport function of time and space need to be further developed, especially when the object under study is a HVDC cable. In the present paper, we propose an evolution of a 1D fluid bipolar charge transport model, taking into account the cylindrical geometry, and its associated effects, i.e. a non-homogeneity of the field and the temperature within the dielectric. Simulations are performed using this one-dimensional cylindrical model, featuring charge injection, transport, trapping, detrapping and recombination, in order to highlight the effects of the cylindrical geometry, i.e. a temperature and a field gradient, on the space charge profiles. A long term simulation is performed until stationary state, to study the capabilities of the model in describing the behaviour of space charge in a MV cable, and the future improvements that need to be performed.
