Аннотация: Analysis of Pb+Pb data for net-charge fluctuations at LHC energies using the HYDJET++ model ispresented. The strongly intensive quantities D and Σ were used to remove the effects related to system volume fluctuations.We employed two versions of HYDJET++ for the analysis. The first one is the standard or default version,whereas the second one is a modification that takes into account explicit event-by-event conservation of the electricnet-charge of produced particles. The inclusion of the canonical net-charge conservation in the model allows for betterdescription of the experimental data obtained by the ALICE and CMS Collaborations. A comparison with calculationsfrom other models is also presented.
