Abstract

The invention provides a method for calculating the maximum power of a linear generator for a high-speed maglev train, comprising: establishing a coordinate system relationship model of the linear generator according to the linear generator for a high-speed maglev train; according to the coordinate system model, Calculate the magnetic induction of the superconducting coil; calculate the induced current of the levitation coil according to the magnetic induction of the superconducting coil; calculate the magnetic induction of the levitation coil according to the induced current of the levitation coil; The magnetic induction intensity is used to calculate the open circuit voltage of the collector coil, and then the maximum power of the collector coil is obtained, that is, the maximum power of the linear generator. The method can accurately and concisely calculate the maximum power of the linear generator for the high-speed maglev train.

Description

technical field [0001] The invention relates to the technical field of rail transit power supply, in particular to a method for calculating the maximum power of a linear generator for a high-speed maglev train. Background technique [0002] Today, among many modern scientific and technological achievements that have attracted worldwide attention, maglev trains have won people's favor for their unique advantages such as suspended non-contact operation, low noise, no air pollution, energy saving, speed and comfort. Maglev train is a high-speed train using non-contact electromagnetic levitation, guidance and propulsion systems, which realizes no mechanical contact between the train and the ground track, thus fundamentally overcoming the limitations of traditional train wheel-rail adhesion, mechanical noise and wear, etc. series of questions. The maglev train can quickly "fly" at a height of 10mm or 100mm from the track, so that the speed of the train can exceed 500km / h. [00...
