摘要:

对高压直流输电系统交流侧产生的谐波进行分析,并针对高压直流输电系统交流侧产生的谐波的特点提出了一种并联有源滤波方案,该有源滤波器采用瞬时无功功率理论进行谐波检测,通过PI控制维持电容电压的稳定,采用高频载波PWM脉宽调制技术使实际输出电流信号跟踪指令电流信号.最后对该有源滤波方案进行了动态模拟仿真,仿真结果表明,该有源滤波方案对高压直流输电系统直流侧产生的谐波的滤除是非常有效的,能够得到理想的结果.

Abstract:

The harmonics generated by the AC side of the HVDC transmission system are analyzed, and a parallel active filtering scheme is proposed for the characteristics of the harmonics generated on the AC side of the HVDC transmission system, the active filter adopts the instantaneous reactive power theory for harmonic detection, maintains the stability of the capacitor voltage through PI control, and uses the high-frequency carrier PWM pulse width modulation technology to make the actual output current signal track command current signal. Finally, the dynamic simulation of the active filtering scheme is carried out, and the simulation results show that the active filtering scheme is very effective in filtering out the harmonics generated by the DC side of the HVDC transmission system, and the ideal results can be obtained.
