“…Although there have been many studies on the harmonic transmission characteristics of power systems in China and other countries, the main targets are high-voltage transmission circuits and urban low-voltage distribution networks [6][7], and there are few studies on the harmonic transmission characteristics of urban high-voltage power grids. For example, Li et al [2] IOP Publishing doi:10.1088/1742-6596/2399/1/012027 2 harmonic conduction of power grids but only used a simplified transmission circuit model to analyze the influence of line parameters on harmonic conduction without considering the impact of substations, resulting in a large error in the conclusion.…”

With the rapid growth of urban power transmission cable scale, the harmonic pollution in the high-voltage power grid is more transmitted to other power grids of different voltage levels, which makes the harmonic transmission more complicated, increases the harmonic emission level, and makes it difficult to quantitatively analyze and study the allowable value of users’ electrical pollution emission. Therefore, in this paper, by establishing the harmonic conduction model of the urban high-voltage power grid and considering the equivalent circuit of transformer and transmission cable in the urban power grid, the parameters of transmission cable harmonic transfer coefficient and the allowable emission value of power quality pollution of the urban power grid are deduced and quantitatively analyzed. Then the harmonic transmission and mutual influence of urban power network harmonics in power transmission cable are analyzed through examples, which is helpful to determine the allowable value of harmonic pollution emission scientifically and reasonably.
