Detailed Description
The following describes in detail a specific implementation process of the starting/generating state switching control method for the open-winding five-phase permanent magnet synchronous motor according to the present invention with reference to fig. 1 to 3.
Fig. 1 and fig. 2 are a block diagram of a starting/power generation integrated system of an open-winding five-phase permanent magnet synchronous motor, and a topological diagram of a main circuit of the open-winding five-phase permanent magnet synchronous motor and a five-phase H-bridge full-control inverter/rectifier, respectively. Fig. 3 is a control flow chart of starting/generating state switching of an open-winding five-phase permanent magnet synchronous motor.
The starting/generating system of the open-winding five-phase permanent magnet synchronous motor mainly comprises the open-winding five-phase permanent magnet synchronous motor, five H-bridge type full-control inverters/rectifiers, a controller, five current sensors, a voltage sensor, a rotary transformer, a filter capacitor, a DC/DC buck converter, a diode, a battery pack and an electric load. The open-winding five-phase permanent magnet synchronous motor is coaxially connected with the liquid oxygen engine, two outlet terminals of each phase winding of the open-winding five-phase permanent magnet synchronous motor are respectively led out, and the two outlet terminals of each phase winding are respectively connected with one bridge arm of an H-bridge type full-control inverter/rectifier. The positive ends of direct current buses of the five H-bridge type full-control inverters/rectifiers are simultaneously connected with the positive end of the filter capacitor, the positive end of the input end of the DC/DC buck converter and the cathode end of the diode; the negative ends of the direct current buses of the five H-bridge type fully-controlled inverters/rectifiers are simultaneously connected with the negative end of the filter capacitor, the negative end of the input end of the DC/DC buck converter, the negative end of the output end of the DC/DC buck converter, the negative end of the battery pack and the negative end of the electric load; the five-phase H-bridge type full-control inverter/rectifier forms a common direct-current bus structure; and the anode end of the diode is simultaneously connected with the positive end of the output end of the DC/DC buck converter, the positive end of the battery pack and the positive end of the electric load.
When the system starts to work, the battery pack supplies power to the five-phase H-bridge full-control inverter/rectifier through the conducted diode, the controller controls the open-winding five-phase permanent magnet synchronous motor to work in a motor running state through the five-phase H-bridge full-control inverter/rectifier, the liquid oxygen engine is dragged to start and accelerate from a standstill state, in the starting process, the controller collects the position of a rotor of the motor through the rotary transformer and calculates the real-time rotating speed n of the motor, and current signals of the five-phase winding are collected through the five current sensors; the controller receives the signals through the acquisition port, and generates PWM pulse signals for driving 5H-bridge full-control inverters/rectifiers connected with the open-winding five-phase permanent magnet synchronous motor to work after calculation by using the signals, so that the open-winding five-phase permanent magnet synchronous motor can drive the engine to start and accelerate.
During the starting and accelerating operation of the engine, the controller also enables the rotating speed n of the motor and the rotating speed n of the liquid oxygen engine to be started in real time1Comparing, once the rotating speed of the motor is higher than the starting rotating speed of the liquid oxygen engine by n1And the controller locks the PWM pulse for driving the 5H-bridge full-control inverters/rectifiers connected with the open-winding five-phase permanent magnet synchronous motor to work, so that the open-winding five-phase permanent magnet synchronous motor is in a free state and does not run as a motor any more. After the liquid oxygen engine is started, the rotating speed is continuously increased under the driving of the liquid oxygen, and the coaxially connected five-phase permanent magnet synchronous motor with the open windings is continuously accelerated under the driving of the liquid oxygen engine.

And then the five-phase permanent magnet synchronous motor with the open winding always works in a power generation state.
When the open-winding five-phase permanent magnet synchronous motor works in a power generation running state, the voltage of a direct-current bus connected with the five-phase H-bridge type full-control inverter/rectifier is higher than that of a battery pack, and the diode is cut off. The open-winding five-phase permanent magnet synchronous motor is charged by the battery pack after the electric energy of which the voltage is higher than the voltage of the battery pack and is generated by the five-phase H-bridge full-control inverter/rectifier is reduced by the DC/DC step-down converter, and simultaneously, the electric energy supplies power for the electric load.
