The invention discloses an equivalent modeling method, device and equipment for a ground energy storage device, and a storage medium. The method comprises the steps of obtaining an actual measurementvalue of a ground energy storage device; calling a corresponding relation among a preset equivalent model, equivalent parameters and preset equivalent conditions, wherein the preset equivalent conditions are obtained according to parameter values of the ground energy storage device; and when the actual measurement value conforms to the preset equivalent condition, establishing an equivalent modelof the ground energy storage device according to the corresponding relation, and determining equivalent parameters of the ground energy storage device. According to the method, the device, the equipment and the computer readable storage medium provided by the invention, the equivalent modeling difficulty of the ground energy storage equipment can be reduced on the premise that the calculation precision is not influenced.
Description
technical field [0001] The invention relates to the field of urban rail transit braking systems, in particular to a method, device, equipment and computer-readable storage medium for equivalent modeling of a ground energy storage device. Background technique [0002] The braking system of urban rail transit trains includes electric braking and mechanical braking. When the train starts to brake, electric braking is usually used, and the traction motor is converted from a motor state to a generator state, and the kinetic energy of the vehicle is converted into electric energy to generate braking force. When the speed drops to a certain value, the electric brake is replaced by mechanical brake. Using electric braking, the regenerative energy is fed back to the DC traction network for use by other trains, which is called regenerative braking. However, this part of electric energy generally cannot be completely absorbed by other running vehicles on the line, and this part of ex...
