The present invention discloses a high-voltage and high-power motor drive protection system and method. The system comprises a high-voltage and high-power power supply, a high-voltage motor drive module, a drive software and hardware protection circuit, a three-phase current detection circuit and a power supply hardware protection circuit. When a motor is instantaneously locked-rotor or the motoris instantaneously subjected to large load disturbance, the drive software and hardware protection circuit generates different protection signals and sends the protection signals to the high-voltage motor drive module according to the current signals of the three-phase current detection circuit, the motor rotating speed and current signals collected by a high-voltage bus current sampling circuit,and the high-voltage motor drive module outputs power configured to turn off the high-voltage motor drive module itself to protect the high-voltage motor drive module itself and a high-voltage motor.The high-voltage and high-power motor drive protection system and method adapt different protection strategies for different fault states to determine fault states of a high-voltage and high-power motor driver and a high-voltage and high-power motor and ensure the safety and the reliability.
Description
technical field [0001] The invention belongs to the general technical field of aerospace, and in particular relates to a high-voltage and high-power motor drive protection system and method. Background technique [0002] With the development of aerospace technology, the number of on-board mechanism products continues to increase, and the demand for transmission equipment for them continues to increase. The power of the motor responsible for electrical transmission continues to increase, resulting in an increase in the volume of the motor. In order to reduce the volume and weight of the motor, it is necessary to Properly reduce the winding current of the motor. In order to keep the power constant, it is necessary to increase the phase voltage of the motor winding. Safety and security, this protection strategy can be adapted to different high-voltage high-power motor drivers. It not only ensures the reliability and safety of the high-voltage and high-power motor, but also imp...
