FIELD: electric engineering, on railroad train of one-phased alternating current with zone-phased adjustment, acting as means for increasing power coefficient. ^ SUBSTANCE: reactive power compensator is connected in turns to one of several sections of secondary winding of traction transformer, powering appropriate shoulders of rectification-inversion transformer. Depending on value of reactive power of circuit, sections of reactive power source are connected to power source. Device for realization of proposed method for controlling reactive power compensator, additionally contains keys, which through reactive power compensator are connected to sections of secondary winding of traction transformer, keys control block, operation mode set-point device, indicators of voltage and current, calculating-measuring block. ^ EFFECT: compensation of reactive power, consumed by electric locomotive, and decreased electric energy consumption. ^ 4 dwg |
