摘　　要：为了补偿光伏并网配电系统中谐波电流,采用矢量静态坐标转换和最大功率点跟踪电压控制相结合的方法,引入有源电力滤波器进行谐波电流检测和补偿,并在光伏发电的试验平台上进行试验。试验结果表明,光伏发电系统的配电网中引入有源电力滤波器能够适时、准确地补偿电流,稳定电压,保证电能质量。To compensate harmonic current for photovoltaic（PV） grid-connected power distribution system,a new method of the vector static coordinate transformation and maximum power point tracking（MPPT）-voltage control was used,and the relevant experiment was done on the student platform,introducing active power filter（APF） to realize the harmonic current detection and compensation.The experimental results show that APF introduced in PV can compensate current and stabilize voltage timely,and guarantee the stability of electrical energy quality.
