Abstract

The invention discloses a double-armature-winding double-salient-pole motor power generation system. Two armature windings are arranged on each stator tooth of a double-salient-pole motor, the armature windings on the corresponding stator tooth are connected mutually in series to form a phase armature winding, the positive ends of one phase armature windings in the two phase armature windings formed by the two armature windings of the corresponding teeth are connected together, are led out through lead wires and serve as the negative electrodes of a double-salient-pole power generation system, and the negative ends of the one phase armature windings in the two phase armature windings formed by the two armature windings of the corresponding teeth are connected with anodes of rectifier tubes. The negative ends of the other phase armature windings are connected together, are lead out through lead wires, and serve as the negative electrodes of the double-salient-pole power generation system, the positive ends of the other phase armature windings are connected with the anodes of the rectifier tubes, cathodes of the rectifier tubes are connected to one point, are led out through lead wires and serve as the positive electrode of the double-salient-pole power generation system to be connected into a load, and thus the novel double-salient-pole motor power generation system is formed. The double-armature-winding double-salient-pole motor power generation system increases the power density of the double-salient-pole motor, and improves the fault-tolerant capability of the system.

Problems solved by technology

[0003] The existing doubly salient pole motors mainly include the following four power generation methods during power generation and operation: (1), switched reluctance generator circuit (SRG): the switched reluctance generator circuit is connected with the phase winding of the motor and the half-wave rectifier circuit, and the rotor of the motor When the phase winding that slides away from the stator poles supplies power to the load through the diode, the armature reaction is magnetization. This method is the simplest, but it only generates electricity when the rotor slides out of the stator, so the output power of the generator is low; (2). Salient pole power generation mode 1 (DSG1): The diode in this power generation mode is opposite to that in the switched reluctance power generation circuit. This connection only generates power in the armature winding phase where the rotor pole slides into the stator pole, and the armature reaction is to go (3) Double salient pole power generation mode 2 (DSG2): In this power generation mode, the phase windings are connected to the three-phase bridge rectifier circuit, and the rotor poles leave and slide The phase windings entering the stator poles all generate electricity, but because the number of rectifier tubes is twice that of the switched reluctance power generation circuit and double salient pole power generation mode 1, and the current flowing through the rectifier tubes is relatively large, the loss is relatively large; ( 4) Doubly salient pole power generation mode 3 (DSG3): In this power generation mode, the windings of each phase are respectively connected to the single-phase rectifier bridge, and the output terminals of the rectifier bridge can be connected in parallel or in series, but there is also the problem of large rectifier tube loss question

[0004] The above-mentioned methods can realize the output of rectified electric energy when the doubly salient motor is generating electricity. However, these methods generally have problems such as low output power or excessive loss.
