Micro-rail transit power supply system, balancing device and control method thereof

Abstract

Microrail transit power supply system, balance device and control method thereof, the balance device includes: a phase commutator, an inductance group, a capacitor group and a controller, the first end of the phase commutator is used to connect each phase of the transformer, the second end Connected with the inductance group or the capacitor group, the controller is respectively connected with the inductance group, the capacitor group, and the commutator; the phase commutator is used to change the phase connected to the inductance group or the capacitor group; the controller is used for The current signal of each phase of the transformer is received, and the inductance group or the capacitance group is controlled to change the inductance value or the capacitance value according to the current signal, and the commutation of the phase is controlled. This application does not need to commutate loads, does not need distributed installation, and does not need too many current transformers, phase commutators and other equipment, and can still achieve three-phase power supply balance in the case of a small number of loads.

Description

technical field [0001] The present application relates to the technical field of rail transit, and in particular to a microrail transit power supply system, a balancing device and a control method thereof. Background technique [0002] The micro-rail transportation system adopts columns and elevated track beams, two-person suspended trolleys are automatically driven, and lines are automatically dispatched and commanded. It is a door-to-door intelligent transportation system. As a light, low-speed, medium-to-low-volume new type of public transportation, the micro-rail intelligent transportation system is a necessary part of an integrated, multi-mode, and three-dimensional public transportation system. Complementary to each other, it is a beneficial supplement and perfection of other public transportation methods. [0003] The trolleys in this system are powered by trolley lines and batteries in the track. There is no trolley line in the turnout, and the battery power is used...

AI Technical Summary

Problems solved by technology

[0003] The trolley of this system is powered by the trolley line in the track and the battery. There is no trolley line in the turnout, and it is powered by the battery when passing the turnout. The trolley line in the track adopts low-voltage single-phase power supply, which will easily cause the three-phase imbalance of the grid power supply.

At present, the existing low-voltage single-phase load balance power supply scheme is not suitable for the micro-rail transportation system, and a new power supply scheme needs to be designed for the micro-rail transportation system
