| 摘要: |
| 研制了满足各种微电网规模并离网切换控制的微电网模式控制器。该装置安装于微电网控制中心，实时采集微电网并网点、分布式发电单元、储能单元及其负荷单元的三遥信息。在接收到调度主站的并离网切换指令或者检测到外网故障后协调控制微电网保护测控设备、储能逆变器、风机逆变器等智能设备，最终实现微电网并离网切换控制。该装置成功应用于鹿西岛微电网示范工程，有着广泛的应用前景。 |

| Abstract: |
| The connect & off-grid device which meets all sizes of microgrid is developed. This device, which is installed on control center of microgrid, real time collects the three remote information of point of common coupling, distributed generation, and energy storage and load. When receiving the scheduling of master station connect & off-grid command or fault detect, the device coordinates smart devices such as micro electrical protection measurement and control equipment, energy storage inverter and fan inverter, realizing micro grid connect & off-grid switch control. This device has been successfully applied in Luxi island micro power grid demonstration project, which has wide range of application in the future. |
