| 摘要: |
| 通过对单相统一电能质量调节器(UPOC)最优稳态功率分析,推导出UPOC最小补偿容量下补偿电压的最优注入角,通过对最优补偿电压注入角度的控制实现统一电能调节器的最优能量控制.在串、并联的控制模块中采用恒频滞环控制来保持开关频率的恒定.在线性及非线性负荷工况下,对电源电压骤变同时伴有谐波的情况进行了仿真.结果表明,该UPOC电路简单、易实现,而且能保证UPQC在最小容量下实现电源和负荷之间的扰动隔离、线路终端功率因数调整,在不增大储能设备容量的前提下延长UPOC的最大可补偿时间,并能较好地克服电源电压引起的负荷节点电压畸变问题. |

| Abstract: |
| The optimal steady-state power of single-phase UPQC(Unified Power Quality Controller) is analyzed,and its optimal injection angle of compensation voltage with the minimum compensation capacity is derived,by which the energy optimal control of UPQC is realized.In the series and parallel control module,the constant-frequency hysteretic control is used to keep the switching frequency constant.Voltage sags of power supply with harmonics are simulated for linear or nonlinear load.Results show that,the UPQC circu... |
