Distributed generation connected controller

The utility model discloses a distributed generation connected controller comprising a power grid common connection point voltage detection unit, three phase voltage transformers, connecting electric reactors, a series connection current transformer, bus capacitors, a bus voltage detection unit, a parallel connection current transformer, a distributed power source voltage current detection unit, a touch screen display unit, and a system controller. The series connection current transformer and the parallel connection current transformer are connected with the bus capacitors through a combined busbar and the bus capacitors, and an output end of the series connection current transformer is connected with the three phase voltage transformers after being connected with the connecting electric reactors. A DSP signal processor is adopted as the system controller. Through the distributed generation connected controller, distributed generation can be improved in electric energy quality, and an electric power system can be improved in security and economic operation level.
