Аннотация: The problem of reducing the quality of electricity is increasingly arising in the process of increasing energy capacities. The decrease in the quality of electricity can be caused by many different factors that manifest themselves under certain circumstances, and therefore have different solutions for their elimination. The most acute problem is the impact of the electricity quality on the energy parameters of electrical equipment and power receivers in the metallurgical industry and on the railway. The article discusses the features of calculating the asymmetry of currents in a traction AC network. The main moments of calculating the settings of balancing devices are determined. The initial calculation data for balancing devices were taken from the dynamic parameters of one of the operating modes of a power transformer TDTNZh 40 MVA, to which two single-phase loads with a capacity of 17 MVA are connected to terminals AB and 10 MVA to terminals BC. The current of the negative sequence and the coefficient of the negative sequence are calculated, and the filter compensating device is also calculated using the parameters of the balancing device. Based on the calculations, the magnitude of the negative sequence current asymmetry was established and the calculation procedure for the balancing device connected to the traction winding of the transformer with the connection group Y/Δ-11 was implemented. © Published under licence by IOP Publishing Ltd.
