摘要
通过对谐波抑制和无功功率补偿理论分析,提出了由一个串联型APF和一并联型APF构成电能质量综合补偿器的设计方案,阐述了基于DSP的数字化控制方法,该设计方案能充分发挥串联型APF能滤去市电中谐波电压、补偿基波电压的作用和并联型APF起消除非线性负载产生的电流的无功分量和高次谐波,使功率因数接近1的作用.
Through the analysis of theory of restraining harmonic and compensating reactive current, We proposes a design of Custom Power, which is composed of a series APF and a parallel APF, and describes the control mode. The scheme can take full advantage of the series APF, which can hold back the harmonic voltage in utility power and compensate fundamental harmonic voltage, and the parallel APF, which is design to eliminate harmonic current and reactive current produced by the nonlinear loads, make the power factor be close to 1.
