Abstract

The invention discloses an electric excitation double-salient pole motor loss-of-magnetic fault fault-tolerant power generation system and a control method thereof. The system is characterized in that two capacitors are introduced based on an original three-phase full-bridge topology to form a split capacitor type topology, moreover, the two capacitors further act as storage capacitors, before an excitation fault occurs, the power is generated in a traditional uncontrolled rectifier power generation mode through the three-phase full-bridge topology, after the excitation fault occurs, switching to a fault-tolerant power generation mode is performed to achieve fault-tolerant power generation through the split capacitor type topology. The system is advantaged in that the system realizes fault-tolerant power generation after the loss-of-magnetic fault of the electric excitation double-salient pole motor, improves the fault-tolerant capability of the system and is suitable for aerospace and other fields with high reliability requirements.

Description

technical field [0001] The invention belongs to the technical field of motor control, and in particular relates to an electric excitation double salient pole motor loss-of-excitation fault fault-tolerant power generation system and a control method thereof. Background technique [0002] Electric excitation doubly salient pole motor is a new type of brushless DC motor developed on the basis of switched reluctance motor. Its stator is wound with armature winding, and there is no winding on the rotor. It has a simple and reliable structure and flexible control. The main difference between it and the switched reluctance motor is that the excitation winding is embedded on the stator. Due to the existence of the excitation magnetic field, when the electric excitation double salient pole motor is used for power generation, it only needs to connect an uncontrolled rectifier bridge to generate power, so it has good fault tolerance performance and is suitable for Due to the advantages...
