| 摘要: |
| 根据220 kV琴韵3C绿色变电站光伏发电系统的建设实例，基于对分布式光伏发电孤岛现象的发生和传统防孤岛效应保护的缺陷分析，研究了基于网络和IEC61850标准的站域孤岛保护的工作原理、抗干扰措施及整定原则。依托站内高速通信网，通过采集变电站区域内与并网光伏发电系统相关部分的实时运行信息，进行集中判断、运算，实现基于站级的防孤岛保护功能。站域孤岛保护解决了传统防孤岛保护存在不可检测区、整定困难和对电网产生电能质量影响的缺点。 |

| Abstract: |
| With the construction of a grid-connected photovoltaic system in 220 kV Qinyun 3C green substation as an example，the occurrence of islanding phenomenon in distributed photovoltaic system is explained and the deficiency of traditional anti-islanding protection is analyzed. The working principle，anti-interference measures and setting rules of a station-domain islanding protection are studied，which is based on the network and IEC61850 standard. To realize the functions of station-domain anti-islanding protection，the real-time substation operating information relating to the grid-connected photovoltaic system is acquired via the high-speed communication network of substation，which is then processed and evaluated centrally. The station-domain islanding protection avoids the defects of traditional anti-islanding protection：undetectable zone，setting difficulty and influence on power quality. |
