摘　　要：提出了不依赖光伏并网结构的基于以太网通信的反孤岛策略,分析了局部反孤岛策略的优缺点。采用低端单片机控制以太网网卡进行数据传输,实现与以太网进行通信。分析表明,这种反孤岛策略能够有效克服局部反孤岛策略存在的非检测区和影响电能质量的缺点,且检测迅速可靠。This paper puts forward the anti island strategy based on communication, analyzes the advantages and disadvantages of local anti - islanding strategy. Low end single chip microcomputer is applied to transmit data by controlling Ethernet card so as to realize Ethernet communication. The analysis shows that the proposed anti - islanding strategy is able to effectively overcome the non - detection zone and the shortcomings of local anti islanding strategies affecting power quality with fast and reliable detection.
