本文介绍了一种单相分布式发电系统与有源电力滤波（APF）的能力，公用事业电流谐波补偿设计。由于DG与电网并联连接，因此其想法是将DG单元功能与并联APF功能集成。利用所提出的方法，DG单元的控制通过向电网中注入具有与电网电压相同的相位和频率的电流来执行，并且其幅度取决于可从可再生源获得的功率。另一方面，负载谐波电流补偿通过向交流系统注入与负载谐波电流相同但相位相反的谐波电流来执行，从而保持线电流几乎为正弦。电网电压的相位检测和负载谐波补偿电流的计算都是由两个结构相同的神经自适应滤波器来完成的，一个是“陷波”结构，另一个是互补的“带”结构。该方法已成功地在数值模拟和实验上进行了测试，适当设计的测试装置
This paper deals with a single-phase distributed generation (DG) system with active power filtering (APF) capability, devised for utility current harmonic compensation. The idea is to integrate the DG unit functions with the shunt APF capabilities, since the DG is connected in parallel to the grid. With the proposed approach, the control of the DG unit is performed by injecting into the grid a current with the same phase and frequency of the grid voltage and with amplitude depending on the power available from the renewable sources. On the other hand, the load harmonic current compensation is performed by injecting into the AC system harmonic currents as those of the load but with opposite phase, thus keeping the line current almost sinusoidal. Both the phase detection of the grid voltage and the computation of the load harmonic compensation current have been performed by two neural adaptive filters with the same structure, one in configuration "notch" and the other complementary in configuration "band". The methodology has been tested successfully both in numerical simulation and experimentally on a suitably devised test setup
