摘要
针对在航空起动发电系统中发电运行状态下,六相永磁同步发电机在发动机转速变化的情况下如何保证输出端直流电压在270 V恒定不变,研究了一种基于SVPWM的最大四矢量的整流控制技术,通过对发电机发出的六相电流进行解耦,得出参与机电能量转换的α-β子空间和x-y谐波子空间,对两个子空间分别进行控制,有效地保证了输出的直流电压恒定不变。通过在Simulink上建立六相永磁同步发电机发电整流系统的仿真模型,得出的仿真结果证明了采用方法的可行性。
For the state of the electric operation of the air starting power generation system,when the condition of the engine speed changes,how the six-phase permanent magnet synchronous generator ensures the output dc voltage 270 V constantly.This paper researches a maximum four vector based on SVPWM rectifier control technology.Through decoupling the six-phase current of generator port,conversion of α-β subspace and x-y harmonic subspace which participate the electrical and mechanical energy conversion is achieved.To control the two subspaces respectively,it guarantees the output of the dc voltage constant effectively.It builds six-phase by the Simulink simulation model of permanent magnet synchronous generator rectification system.It is concluded that the simulation results prove the feasibility of the method.
