Control system used for railway traction transformer station

Abstract

The invention relates to a control system used for railway traction transformer station. A power supply bus is arranged on the railway traction transformer station and used for providing power for all controlled trains. The system comprises a centralized control device, a distributed control device and a communication device. The centralized control device is connected with the railway traction transformer station and the power supply bus and used for acquiring load states of the power supply bus and sending a control signal to all controlled trains. The distributed control device is connected with the controlled trains and used for receiving control signals sent by the centralized control device and controlling the controlled trains to be subjected to load adjustment. The communication device is connected with the centralized control device and the distributed control device and used for achieving transmission of the control signals. Compared with prior art, the control system is advantageous in that the capacity of a single power adjusting device is low; unified management and coordination of each load of the railway traction transformer station can be achieved; and the control system achieves stable control and is easy to achieve.

Description

technical field [0001] The invention relates to the control field of railway traction substations, in particular to a control system for railway traction substations. Background technique [0002] Since there are usually multiple trains running on the power supply bus of the railway traction substation, there are trains close to the railway traction substation and trains far away, both accelerating trains and decelerating loads. Therefore, the active power, reactive power and harmonic content of the railway traction substation often change, and it needs to be adjusted. Otherwise, if the adjustment is not good, the negative sequence of the railway traction substation will be serious and the power quality will deteriorate. There are two common methods at present. One is centralized control, that is, a single regulating device is added to the railway traction substation for regulation, but the disadvantage of this method is that the capacity and volume of the regulating device...

Problems solved by technology

The disadvantage of this kind of control is that each regulating device is in a separate array, and there is no unified management and coordinated control among them. Once the coordination is out of control, the distributed regulating devices will be disassembled, which will eventually make the overall power quality management of railway traction substations unsatisfactory.
