摘要:
设计了一种电力电子变压器,其采用AC/DC/AC型拓扑结构,输入级采用有功和无功的解耦控制,中间级采用开环控制以获得较快的同步响应速度,输出级以配电系统电压控制为目标、采用基于瞬时值反馈的定交流相电压控制。仿真结果表明,该电力电子变压器及其控制方法具备优良的改善电网电能质量的能力,能够显著降低在电网电压跌落、骤升、不平衡、频率变化等工况下电能质量对用电设备造成的不利影响。
Abstract:
It designed a power electronic transformer (PET) with AC/DC/AC topological structure. Decoupling control method for active power and reactive power was adopted in the input stage, and the open-loop control was chosen in the middle stage to achieve fast synchronizing response speed. Constant AC phase voltage control based on the instantaneous value feedback was applied on the output stage with the aim of voltage control in distribution system. Simulation results show that the proposed PET and the control strategy has excellent ability to reduce the negative impact of power quality on electrical equipment significantly such as voltage dip, swell, unbalance and the frequency deviation.
