In this paper a model that allows to self-consistently calculate the potential distribution and plasma space charge distribution near an infinite one-dimensional chain consisting of highly charged dust particles, which is influenced by an external electric field, is presented. The results show that with a gradual increase of the external field amplitude, unlike in the case of an isolated dust particle, there is no anisotropy in the distribution of the space charge; however, with a further increase of the electric field power, zones of local potential maxima appear between the dust grains.
