提出了一种光伏并网发电系统功率因数控制和孤岛检测方法。通过指定的控制电路,可以观察到逆变器输出端的偏差。再加上开发的算法,这种偏差作为一个有用的援助,以更有效地检测孤岛。所提出的方法已经过测试,通过不同的情况下,包括电网的损失和并行操作。仿真研究和硬件电路验证了该方法的有效性。通过测试结果,它们有助于巩固所考虑的应用程序的方法的可行性和实用性。
An approach to power-factor control and islanding detection of a grid-connected photovoltaic system is proposed. With the designated control circuit, deviation at the output of the inverter can be observed. Coupled with the algorithm developed, this deviation serves as a useful aid to detect islanding more effectively. The proposed method has been tested through different scenarios, including the loss of grid and operation in parallel. Simulation studies and hardware circuits were both made to validate the effectiveness of the method. With the test results they help consolidate the feasibility and practicality of the approach for the applications considered.
