Abstract

In parallel operation of high-voltage power lines of automatic block system in the areas of splicing electric traction systems AC and DC there are failures in the auto-lock devices, caused by failure to conditions of parallel operation of transformers. Inconsistency of their work caused by various schemes of traction substations connecting AC and DC lines to the external power supply, a different number of transformation steps, as well as various schemes and groups of windings connection of automatic block system of transformers. The article analyzes the conditions of parallel transformers auto-lock on the adjacent traction substations different electric traction systems and solved the problem of providing their coordinated work.
