The invention provides a data synchronization method and device. The method comprises the following steps: coding the data volume of power station equipment under a centralized control sub-station; establishing a corresponding relationship between a centralized control master station and the centralized control sub-station according to the coding; creating a power grid equipment model for the power station equipment under the centralized control sub-station according to the coding, acquiring data information of the power station equipment, and storing the data information and the power grid equipment model into a historical library of the centralized control sub-station; periodically synchronizing the data information under the centralized control sub-station and the power grid equipment model to a historical database of the centralized control master station according to the coding; and synchronizing real-time data and real-time alarm information of the centralized control sub-station to a real-time library of the centralized control master station according to the coding. Thereby, the problem of long data information recording time and low deployment efficiency caused by manually achieving the corresponding relationships currently established between the centralized control master station and the centralized control sub-station can be solved.
Description
technical field [0001] The present application relates to communication technology, in particular to a data synchronization method and device. Background technique [0002] The photovoltaic power generation centralized control system can realize unified remote centralized monitoring of the owner's scattered photovoltaic power plants. Through the photovoltaic power generation centralized control system, the operation of the photovoltaic power plant can be effectively grasped in real time to ensure the reliability and stability of the solar photovoltaic power generation system. run. [0003] The centralized control system of photovoltaic power generation includes centralized control master station and centralized control substation. At present, the traditional centralized control system uses telecontrol protocol communication protocol to access the data of centralized control substation. The uploaded data information provided is manually entered into the configuration library...
