单相三电平脉冲整流器无差拍预测直接功率控制
Deadbeat Predictive Direct Power Control of Single-phase Three-level Pulse Rectifiers
摘要
Abstract
In order to improve the controller’s dynamic response and precision of single-phase three-level pulse rectifier applied in China railways high-speed 2 (CRH2) electric multiple units, a single-phase three-level pulse rectifier was firstly modeled with mathematical expression. Then the operating principle of direct power control (DPC) based on PI controller with the fixed switching frequency was analyzed. On this basis, a single-phase deadbeat DPC with autoregressive power prediction method was proposed. Compared with the traditional PI DPC method, the proposed DPC method can not only reduce the complexity of hardware design and software programming without the main voltage’s phase detector, such as phase-locked loop (PLL), but also improve dynamic response of the rectifier with load change with active and reactive power autoregressive prediction. Furthermore, a single-phase three-level space vector pulse width modulation (SVPWM) embedded neutral point voltage balance was combined with the proposed deadbeat predictive DPC method as the control system of single-phase three-level pulse rectifier. Finally, The deadbeat predictive DPC and the traditional DPC with PI controller were compared and verified in computer simulation and hardware-in-loop experimental test. A comparison of simulation and experimental results verifies the feasibility and effectiveness of the adopted deadbeat predictive DPC method.关键词
