active frequency drift with positive 主动移频式孤岛检测
According to joining the different disturbance, this method can be divided into active frequency drift with fixed disturbance method and active frequency drift with feedback method.
该方法根据加入扰动的不同,可以分为固定扰动的主动移频式孤岛检测方法和带反馈的主动移频式孤岛检测方法。
The results indicate that non-detection zone of active frequency drift with feedback method is obviously less than non-detection zone of active frequency drift with fixed disturbance method.
结果表明,带反馈的主动移频式孤岛检测的检测盲区明显小于固定扰动的主动移频式孤岛检测的检测盲区。
This paper proposed a novel active frequency drift with feedback based on single-phase single stage PV grid-connected generation system for the complexity of the control in traditional method.
基于单相单级光伏并网发电系统,针对传统主动式频率偏移法控制的复杂性,采用了一种新颖的带反馈的主动式频率偏移法。
