    • The invention relates to decentralized energy production. In particular, the invention concerns a system for coupling a monophase power source (25,26) to an internal multiphase power network (25A,25B,25C) of a household, company, or other property. The internal network is further connected to an external power distribution grid (L1,L2,L3). The system comprises an interface unit (22) comprising a first connection point (22A) for said monophase power source and a second connection point (28A,28B,28C) for said multiphase power network, the interface unit allowing for monophase power from the monophase power source to be fed to the multiphase network, and means (23A,23B,23C) functionally connected to the interface unit for monitoring the loading states of individual phases of the multiphase power network. The interface (22) has coupling means (27) to couple monophase power to selectively one of the phases of the multiphase power network based on the loading states of the individual phases of the multiphase power network. The invention improves cost-efficient usage of locally produced power and saves transmission losses.
    • 本发明涉及分散的能源生产。 特别地,本发明涉及将单相电源(25,26)耦合到家庭,公司或其他财产的内部多相电力网络(25A,25B,25C)的系统。 内部网络进一步连接到外部配电网(L1,L2,L3)。 该系统包括接口单元(22),其包括用于所述单相电源的第一连接点(22A)和用于所述多相电力网络的第二连接点(28A,28B,28​​C),所述接口单元允许来自所述单相电源的单相功率 供给多相网络的电源以及功能上连接到接口单元的装置(23A,23B,23C),用于监视多相电力网络各个相的负载状态。 接口(22)具有耦合装置(27),用于基于多相电力网络的各个相位的负载状态,将单相功率选择性地耦合到多相电力网络的选择性的一相。 本发明提高了本地生产的功率的成本效益,节省了传输损耗。
