摘要
提出一种基于准比例-谐振控制与陷波器的新型地铁辅助逆变器控制策略,通过理论分析,实现在α-β坐标系下的输出电压谐波消除;并实现在输出电压存在不对称、谐波干扰等情况下的高精度锁相控制。通过软件仿真及硬件试验验证,该控制策略可有效抵抗非线性负载及单相负载对地铁列车中压母线(3N380 V)的干扰,实现逆变器无静差运行,符合我国地铁运营节能、高效的目标。
A new control strategy of subway auxiliary inverter based on quasi-proportional-resonant control and notch filter was proposed.Through theoretical analysis,harmonic elimination of output voltage inα-βsystem was realized.In addition,high-precision phase-locked control was achieved in the case of asymmetric output voltage and harmonic interference.Through software simulation and hardware test,the control strategy can effectively resist the interference of non-linear load and single-phase load to the medium voltage bus of subway train,and realize the static error-free operation of inverters.It conforms to the goal of energy saving and efficient operation of subway in China.
