中文摘要:

有源电力滤波器的直流侧电压值对其补偿效果有很大的影响,主要针对有源电力滤波器直流侧电压的取值与控制进行研究。设计了有源电力滤波器实验系统,在此基础上,理论分析了直流侧电压与补偿电流之间的数学关系；通过不同条件下的实验深入分析了直流侧电压值与补偿特性之间的关系；根据有源电力滤波器的启动特性,设计了相应的PI算法,消除了启动阶段电容电压超调大的不利因素。实现了直流侧电压的合理选择与有效控制。

英文摘要:

Because the dc side voltage value filter has a great influence on the compensation effect of active power filter,the article mainly studies the value selection and the control of dc side voltage for active power filter. It designs the experiment system of active power filter, and on this basis, the theoretical analysis of the mathematical relationship between the dc side voltage and offset current is done;Through experiments under different conditions the relationship between the compensation characteristic and dc side voltage is analyzed;According to the startup characteristic of the active power filter, It designs the corresponding PI algorithm and eliminates the unfavorable factor such as large overshoot of capacitance voltage at the startup phase. Finally it realizes the reasonable choice and effective control of dc side voltage.
