Abstract
The utility model discloses a multifunctional string type energy storage inverter PCS and an energy storage power generation system, a local controller LCU module, a battery control unit BCU module and a PCS control unit are integrated in the energy storage inverter PCS, the PCS control unit and the BCU module are electrically connected with an internal communication interface of the LCU module based on internal communication interfaces, and the PCS control unit and the BCU module are electrically connected with an external communication interface of the LCU module based on internal communication interfaces. And information mutual transmission is realized based on the LCU module. The PCS control unit sends running state information of a unit to the LCU module, the BCU module sends collected battery monomer information to the LCU module, and the LCU module converts the received information into a corresponding communication protocol and transmits the communication protocol outwards through an external communication interface of the LCU module; external information is received through an external communication interface of the LCU module, is converted into a corresponding communication protocol, and is transmitted to the PCS control unit and the BCU module. According to the utility model, the LCU and the BCU are integrated in the PCS, the integration density is high, the wiring complexity in the energy storage cabinet is greatly reduced, and the occupation of the control assembly on the space of the cabinet body is reduced.
