Selected problems of cooperation between a synchronous machine and a group of asymmetric receivers in a low-voltage network of an industrial plant

The paper presents an analysis of the effect of a group of asymmetric receivers of R, L type on the battery of static capacitors and a synchronous machine connected to a common low-voltage network of an industrial plant, supplied from an own transformer. In result of the analysis a proposal of a limit of the degree of the receiver asymmetry is formulated with a view to prevent harmful effect on the synchronous machine and the battery of capacitors. The analysis considers the influence of the asymmetry on the currents flowing in the transformer, the synchronous machine, and the capacitor.
