[Abstract]:Switched reluctance motor (SRM) has the advantages of simple structure, good reliability, high torque, high power density and suitable for high-speed applications. It has a broad application prospect in the field of new energy. In this paper, the closed loop control system of switched reluctance motor is taken as the research object, the application of switched reluctance motor system based on new energy supply is studied, and the reusing of motor windings and switching of different working modes under the same system are studied. The application of switched reluctance motor in the field of new energy has been explored and tried. Firstly, the research status in the field of new energy is reviewed, the photovoltaic pump and the new energy vehicle are selected for literature review, and the working principle and research progress are introduced. At the same time, several main research directions of switched reluctance motor are read and analyzed. The structure, principle and operation characteristics of switched reluctance motor (SRM) are introduced. The principle of speed regulation under angle position control (APC) and current chopper control (CCC) is analyzed in detail. The advantages and disadvantages and applicable conditions of different power converters are compared. The experimental platform of switched reluctance motor is built, the closed-loop control system is designed, the principle of closed-loop speed regulation under PI control strategy is studied, and the components and parameters of the hardware and software platform are introduced. In order to verify the performance of the system, motor speed regulation experiments were carried out under different control modes and operating conditions. According to the application of switched reluctance motor system in photovoltaic pump, a new structure of switched reluctance motor system is proposed, which can realize the new energy battery with only one set of power converters. The energy conversion between the energy storage and the switched reluctance motor (SRM) and the function of maximum power point tracking. Through the research of circuit working mode, control principle, simulation and experiment, the validity of the system in photovoltaic array single power supply mode, battery charging mode and hybrid mode is verified. Aiming at the application of switched reluctance motor system in charging without charging piles, a new on-board charging circuit structure based on inductance reuse of motor windings is proposed, which can work in both Buck mode and Boost mode. At the same time, the constant current charging can be realized by means of PI control strategy, which can meet the charging requirements of different voltage levels and improve the charging efficiency. Simulation and experimental research show that the system has flexible use characteristics. Switched reluctance motor (SRM) has more application space and direction in the new energy field besides photovoltaic pump and charging without charging pile. The circuit structure, control mode and research ideas presented in this paper are helpful to the further application of switched reluctance motor in the field of new energy.
