The invention belongs to the field of motor simulation modeling, particularly relates to a real-time simulation modeling method, system and equipment for a segmented power supply linear induction motor, and aims to solve the problem that the real-time simulation modeling of the segmented power supply linear induction motor cannot be realized in the prior art. The method comprises the following steps: acquiring a mathematical model of the linear induction motor in a bidirectional thyristor switching process through a linear speed v of a rotor, a ratio ax of covering a stator by the rotor and a power supply voltage Uss by a mathematical model in a normal power-on state of the segmented power supply linear induction motor, obtaining the current and the on-off signal Ks of the bidirectional thyristor when no mover covers, and obtaining the actual on-off state Fs of the bidirectional thyristor; and calculating to obtain the current and thrust in the thyristor switching process, and judging the final current and thrust output by the stator according to the ax value. Real-time simulation modeling of the segmented power supply multi-phase linear induction motor is realized quickly and effectively.
Description
technical field [0001] The invention belongs to the field of motor simulation modeling, and in particular relates to a real-time simulation modeling method, system and equipment of a segmented power supply linear induction motor. Background technique [0002] The multi-phase long stator linear induction motor has the characteristics of high power, low thrust fluctuation, strong fault tolerance and simple mover structure. It is suitable for short-term, high-thrust and high-speed electromagnetic propulsion systems, and can be used in the fields of industry, transportation and national defense. The 6-phase long stator linear induction motor can be divided into 6-phase symmetrical windings and double Y phase-shifted 30° windings. The double Y phase-shifted 30° windings are an asymmetrical six-phase system, but its magnetic circuit can be equivalent to a symmetrical twelve phase system. The double Y-phase-shifted 30° winding structure can eliminate the 5th and 7th harmonic magne...
