摘　　要：研究并制作了一台用于三相四线制配电网的串联混合型滤波器实验样机,采用基波电流控制的策略,可以显著抑制非线性负载产生的谐波电流对电网的影响。实验装置采用以数字信号处理器(DSP)为核心的控制电路实现实时运算与控制。实验结果表明整套装置具有优良的滤波性能与实用价值。A prototype of series hybrid active power filter (SHAPF) applied to three-phase four-wire electric distribution systems is studied and developed. The principle of fundamental current control is adopted and the effect of harmonic currents generated by nonlinear loads on power system is reduced significantly. Experimental equipment controlled by DSP achieves realtime calculation and control. Experimental results show that the equipment provides excellent filtering performance.
