摘　　要：根据近年来我国光伏发电产业的发展现状以及光伏电站并网标准的相关规定,针对开展防孤岛能力试验需要考虑的逆变器容量、并网点电压等级、负荷加载、地理环境等实际问题,开发了一套具有380 V/10 k V/35 k V多电压等级接入、最大容量为1.5 MW的移动式光伏电站防孤岛能力检测平台。该平台能够满足不同类型光伏电源防孤岛能力试验的需要。选定曲阳县某光伏电站开展现场防孤岛能力检测试验。试验结果证明该检测平台能快速、准确地检测到并网逆变器是否具有防孤岛能力。According to the current development of photovoltaic industry and the relevant provisions of the standards for PV power station connected to power grid in recent years, a testing platform to detect the ability of anti-islanding is developed and designed. The mobile an-islanding detection platform can be accessed to a set of multi-voltage, such as 380 V, 10 k V, 35 k V, with the maximum capacity of PV power station being 1.5 MW, considering the capacity of the inverter, power grid＇s voltage level, load loaded, geographical environment and so on. Field tests have been conducted successfully on a PV power station in Quyang. The results show that whether the inverter connected to power grid owes the ability of an-islanding can be detected quickly and accurately by the test platform.
