摘要
在基波磁通补偿有源电力滤波器系统中,补偿变压器参数的设计对滤波效果起关键作用。该文通过理论推导、仿真等手段,研究了补偿变压器的励磁电感、漏感对系统电压、电流幅值及谐波的影响。结果表明,补偿变压器的参数对系统影响复杂,但可通过实验仿真手段优化有源电力滤波器的设计,从而为工程设计提供基础。最后搭建了基于RT-LAB的半实物实时实验平台,经实验证明了基波补偿有源滤波器方案的可行性及补偿变压器参数对系统的影响。
The design of compensation transformer parameters plays a key role in the filtering effects of the system of active power filter based on fundamental magnetic flux compensation. The influence on system voltage, current amplitude and harmonic caused by compensation transformer＇s magnetizing inductance and leakage inductance is studied through theoretical derivation and simulation, and the result shows that the parameters of compensation transformer have complex effects on the system. However, the design of active power filter can be optimized through simulation and experiment, which provides a theoretical basis for the engineering design. Finally, a semi physical real-time experiment platform based on RT-LAB is built to verify the feasibility of fundamental magnetic flux compensation filter and the effects of compensation transformer, parameters on the system.
