摘要:
孤岛检测是基于逆变器并网的分布式发电系统的必备功能。传统的滑膜频率偏移孤岛检测法,检测快速性随负载品质因数的增大而降低。反正切滑膜频率偏移法,它具有传统SMS法的优点,但其检测性能同样受负载品质因数的影响。首先对反正切滑膜频移法的工作原理、断网后分布式系统并网点电压频率的变化轨迹进行了分析,得出该算法在不同参数下的盲区分布,其次通过合理设置算法参数,以减小孤岛检测盲区,提高检测速度。最后,应用仿真验证所提方法的有效性。
Abstract:
Islanding detection is an essential function of the distributed generation system based on the grid connected inverter. In the traditional method of Slide-Mode Frequency Shift, the detection speed decreases with the increase of load quality factor. Arctangent Slide-Mode Frequency Shift method(arctan_SMS) has the advantages of traditional SMS method, but its detection performance is also affected by the load quality factor. Firstly, the working principle of arctangent sliding film frequency shift method and the change track of voltage frequency of the distributed system after grid disconnection are analyzed, and the non-detection zone(NDZ) of distribution of the algorithm under different parameters is obtained. Secondly, the NDZ is reduced and the detection speed is improved by setting the algorithm parameters rea-sonably. Finally, the effectiveness of the proposed method is verified by simulation.
