Investigation of the process of transformers switching on through the longitudinal compensation unit

Abstract

The installation of longitudinal compensation (LCC) of voltage losses in the distribution network of the mining site was first tested in production conditions at one of the sites of the Kirov mine of the Slantsy Combine in 1964. In the experimental operation of the CPC proved the feasibility and efficiency of automatic voltage regulation by series capacitors in the network of the site. Inclusion of the longitudinal compensation unit allows to get voltage increase at the longwall face distribution point by 20-25% at engine starts and by 10-15% at nominal load ...
