提出了一种利用谐波电流作为有源信号的孤岛检测方法。特别是，为了有效地注入有功信号，我们提出了一种将DG有功信号产生的谐波电压与负载的谐波电流产生的谐波电压同步的方法。为了验证所提方法的有效性，我们用PSCAD/EMTDC进行了仿真，并用电路理论进行了计算。我们澄清了同步进样可以大大减少孤岛检测时间。
We have proposed an islanding detection method using the harmonic current as an active signal. In particular, in order to inject the active signal efficiently, we have proposed a method to synchronize the harmonic voltage caused by the active signal of DG with the harmonic voltage caused by the harmonic current of the load. To verify the validity of the proposed methods, we performed the simulation by PSCAD/EMTDC and the calculation by circuit theory. We clarified that the synchronous injection can be greatly reduced the islanding detection time.
