Integrated Communication Technology for Supervisory Control and Data Acquisition System of PV Power Station

Large-scale grid-connected PV power station and customer-premise grid-connected PV power station are currently the main types of PV power station in China. Because of various scale of construction, operation environments, installation locations and applications, the SCADA (supervisory control and data acquisition) system of PV power station is flexible and complex. This paper studies and proposes an integrated communication platform solution which integrates optical fiber communication, power line carrier communication and wireless communication. The solution has characteristics of uniform network management, flexible configuration and strong adaptability, which can fulfill the requirements of the SCADA system of multiform PV power station.
