摘　　要：由于微电网中含有大量非线性器件,运行过程中会产生大量谐波。为治理孤岛微电网中的谐波问题,在微网逆变器P-f下垂控制方法的基础上提出一种带有源电力滤波器(APF)谐波抑制功能的统一控制器,并在谐波电流检测过程中采用一种改进型d-q算法。搭建了系统仿真模型和实验平台,仿真和实验结果表明采用提出的统一控制器能够实现APF功能,有效地抑制谐波电流。Due to the large number of nonlinear loads in the microgrid, a large number of harmonies are generated in the process.In order to suppression the harmonic problem in the island microgrid, on the basis of the P-f droop con- trol method of the microgrid inverter, a kind of unified controller with active power filter（APF） harmonic suppression function is proposed and an improved d-q algorithm is adopted in the detection of harmonic current.System simula- tion model and experimental platform are built, using the proposed unified controller to realize the function of APF and the harmonic current can be suppressed effectively.
