At present, the control system of electric traction motors is widely used in four-regulators collected on thyristors in a bridge rectifier circuit. The feature switching processes in them are needed to introduce an artificial delay of the thyristors opening angle, which reduces the average value of the power factor up to 0.8. The article assesses the effectiveness of the combination of the rectified voltage from the point of view of increasing the energy performance of the band rectifiers for controlling the traction motor freight locomotives operating on alternating current. With this regulation the greatest effect is achieved in the first control zone, under normal conditions when the power factor is particularly low (0.2 ... 0.6). The expected improvement of the average power factor of the first zone will be about 22%, and taking into account the duration of the performance in all working areas, it should be about 5-10% |
