Title:
POWER GENERATION SYSTEM AND COMMUNICATION APPARATUS FOR POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/022835
Kind Code:
A1
Abstract:
The present application relates to an inverter in a power generation system, the inverter being used for converting a direct current (DC) inputted from a DC side device into an alternating current (AC) used to supply power. The inverter comprises a control apparatus and a communication apparatus. The control device is used to control the inverter to convert a DC inputted from the DC side device into an AC used to supply power. The communication device is coupled with the control device and uses a DC power line to send a networking information request signal used for requesting networking information to the DC side device in the power generation system, the frequency of the networking information request signal being within a first frequency band, receiving the networking information from the DC side device, and sending a control signal to the DC side device, the frequency of the control signal being within a second frequency band and being used to control working parameters of the DC side device; the first frequency band is lower than the second frequency band. The present application can effectively prevent crosstalk during networking by an inverter and a DC side device. In addition, the present application also relates to a communication apparatus, a DC side device and a power generation system.
