Operation control method for train

Abstract

The invention provides an operation control method for a train. The operation control method comprises the following steps of: obtaining relation between the energy loss and the highest operation speed of the train according to the traction characteristic of the train, the brake characteristic of the train and the air-resistance characteristic; obtaining highest operation speed when the energy loss of the train is minimum according to the relation between the energy loss and the highest operation speed of the train; obtaining the constant-speed operation time and the speed when the maximum braking is started according to the highest operation speed; obtaining an energy-saving train operation curve according to the highest operation speed, the constant-speed operation time and the speed when the maximum braking is started; controlling the operation of the train according to the energy-saving train operation curve. By the train operation control method provided by the embodiment of the invention, the train operation curve under the condition of minimum energy consumption of the train can be obtained according to the traction characteristic of the train, the braking characteristic of the train and the air resistance characteristic, and the obtained energy-saving train operation curve is more accurate, so that the energy-saving efficiency for operation of the train is higher.

Description

technical field [0001] The invention relates to the field of train control, in particular to a train energy-saving operation control method. Background technique [0002] Numerous research data at home and abroad show that the most energy-saving control principle of train operation is composed of four operating conditions: maximum traction, constant speed operation, coasting and maximum braking. In order to realize the energy-saving operation of the train, it is necessary to draw the train operation curve and control the operation of the train according to the train operation curve. Under the four operating conditions of maximum traction, constant speed running, coasting and maximum braking, the train operating curve can be determined as long as the transition points of each train condition are determined. To determine each conversion point, it is necessary to determine the maximum running speed, the time of running at a constant speed, and the speed at which the maximum br...
