Problems solved by technology

[0004] The existing energy-saving control methods for rail train operation all adjust the train speed offline, and fail to propose an effective online and real-time method for saving electric energy, nor do they consider the problems of timetable adjustment and train adhesion at the same time

Embodiment

[0110] Assuming that train A will depart for the next stop, train A will receive operation data from the train control center. The train control center determines the running time between train stations A according to the needs of timetable punctuality and system traffic volume, and then plans the running time-speed curve between train stations. The inter-station running time-speed curve of train A can be converted into the arrival time of each mileage distance and the train speed of each mileage, and the marking interval of each mileage is determined according to the system response time and related requirements. After starting, train A will adjust the speed according to the running speed curve, so as to facilitate the control of travel.

[0111] When the train A travels between stations, in addition to adjusting the speed according to the time-speed curve of the train control center, the method proposed by the present invention will use the level of the traction power supply...

Abstract

The present invention relates to the technical field of rail transportation operation control, and discloses a rail train electric energy saving operation control method, which comprises the following steps: S1, predicting a time-speed curve of a train between stations during operation according to train operation data; and S2, adopting the curve to control the train to operate, and adjusting an operation mode, a speed and an acceleration of the train at the next time according to a voltage of the current traction power supply grid / third rail, resistance on the train, and adhesion during the train operation process. According to the present invention, a real-time train electric energy saving operation manner is determined according to the real time voltage of the current traction power supply grid / third rail and the current linear situation; and the real-time train operation adhesion is considered, and it is ensured that train slipping can not be caused during train operation.

Description

technical field [0001] The invention relates to the technical field of rail transit operation control, in particular to an electric energy-saving operation control method for rail trains. Background technique [0002] The cost of rail transit in every city is very high, not only the construction cost is high, but also the annual operation and maintenance cost of the line after the official operation is opened to traffic is very high, especially the power consumption cost of the line is the most serious, resulting in the high operating cost of urban rail transit No less, this has become the most prominent problem of urban rail transit. Therefore, reducing the energy consumption of urban rail transit and reducing the total electricity consumption has become one of the most effective ways to reduce the operating cost of urban rail transit. [0003] The main form of energy consumption in the operation of urban rail transit system is electricity consumption. According to the st...
