Abstract

The present invention provides a distributed power generation traction network train operating state identification method, comprising: obtaining the voltage and current phasors of the head end of the traction network segment; power flow) to obtain the train power of this segment, based on the different determination conditions of the active power of the segment, identify the running state of the train in the segment of the traction network, and by calculating the active power of the entire line, identify the combined operation of the trains in the traction network of the entire line state. The train running state identification method of a distributed power generation traction network provided by the present invention is to identify the train running state through its power flow distribution. The principle is correct, the algorithm is simple and reliable, and it can be directly applied to the traction network system of distributed power generation. Energy intelligence management of power generation system provides the basis.

Description

technical field [0001] The invention relates to the technical field of AC electrified railway power supply. Background technique [0002] The existing traction power supply system train running state identification is only applicable to the traction power supply mode with no other power generation devices connected to the traction network, and for the new distributed multi-source power generation traction power supply system, due to the ) distribution and composition changes, it is impossible to identify the train running status of the entire traction network at the feeder of the traction substation, and it is also impossible to make further decisions for the control of the power generation device. Therefore, it is necessary to propose a new method to realize the control of the entire traction network Train running status identification, this new identification method is not only suitable for train running status identification in distributed multi-source power generation tr...
