AUTOMATIC VOLTAGE CONTROL DEVICE AT TRACTION SUB-STATION AND IN OVERHEAD SYSTEM Russian patent published in 2011 - IPC B60M3/02 H02M5/257 

FIELD: transport.

SUBSTANCE: invention refers to automatic voltage control devices in overhead system on electrified railway transport. Device includes two speed control units of moving object, speed detecting unit of moving object, setting device of limit speed value of moving unit, formation unit of maximum voltage stabilising level, OR element, and transformer commands shaping unit. Output of each speed control unit is connected to the first input of the appropriate speed detecting unit. The second input of each of speed detecting units is connected to output of setting device of limit speed value. Output of each detecting unit of limit speed value is connected to input of shaping unit of maximum voltage stabilisation level at the sub-station by means of OR element. Output of shaping unit of maximum voltage stabilisation level at substation is connected to the third input of shaping unit of transformer commands.

EFFECT: higher reliability.
