Operating conditions of electric energy storage system in DC traction power supply for single-track sections of railways

Considered are the issues of using electric energy storage system in traction power supply direct current a single-track section. An overview main directions domestic and foreign research field these systems to increase capacity efficiency is given. Modeling operation based on calculation load graphs within boundaries inter-substation zones, formed depending conditions for passage trains railway The provisions method choosing locations determining parameters considered. On example one zones Sverdlovsk railway, influence active sectioning station minimum voltage level at pantograph rolling stock shown. degree charge corresponding frequency distributions given, which make it possible evaluate operating formation load, as well charging characteristics post. section under consideration, dependence discharge depth nominal intensity Based results calculations, an evaluation was made options passing train batches even odd direction comparison with schedule performed operation. range variation values obtained. Comparison accumulation single- double-track sections railways, including those predominance passenger traffic, carried out.
