FIELD: electrical engineering.
SUBSTANCE: invention relates to electrified railway power supply systems. Proposed substation comprises converter transformer (1), rectifier-inverter unit (2), power storage capacitor bank (4) and reactor (5). Aforesaid power storage capacitor bank (4) has its one end connected to positive terminal via primary contactor (7) and stabiliser or limiter (3). Its other end is connected with generic point of reactor (5) and rail (9). Current stabiliser or limiter (3) is connected to shunting contactor (6). One leadout of discharge contactor (8) is connected to generic point of reactor (5) and rail (9), the other one being connected to generic point of current stabiliser or (3) and primary contactor (7). Discharge contactor (8) is interlocked with primary contactor (7).
EFFECT: higher voltage stability, higher reliability, reduced losses.
