Embodiment Construction
[0040] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings:
[0041] like figure 1 As shown, a clustering method of the present invention for data transmission of distributed photovoltaic power plants is applicable to the current distributed photovoltaic power plants according to the topology structure of clustered distributed photovoltaic power plants, and clustered distributed photovoltaic power plants. Including multiple solar panel arrays, DC combiner boxes sequentially connected to the solar panel arrays, photovoltaic DC power distribution cabinets, photovoltaic DC inverters, and AC power distribution cabinets, such as figure 2As shown in the figure, the solar panel array is connected to the inverter, and the data collected at the inverter is periodically sent to the intelligent substation in the area, and then the intelligent substation uploads the data to the base station and finally to the cloud. The smar...

The invention discloses a clustering method used in data transmission of a distributed photovoltaic power station, which is applicable to the technical field of wireless communication. Firstly, all inverters are sorted in ascending order according to the distance from the inverter to the intelligent substation, and the inverter at the top of the ranking is selected as a cluster head. For other adjacent inverters within a certain range from the cluster head, calculate and judge if If the energy consumption generated by data transmission to the intelligent substation via the cluster head is less than the energy consumption generated by direct data transmission to the intelligent substation, the adjacent inverter is added to the cluster, and the same is done for the unclustered inverters. The clustering process until all inverters are clustered. It effectively reduces the total energy consumption of data transmission from inverters to intelligent substations in the region, has low data transmission traffic cost, low difficulty in operation and maintenance, and high efficiency.
Description
technical field [0001] The invention relates to a clustering method in data transmission, which is especially suitable for wireless data transmission of distributed photovoltaic power station, and belongs to the technical field of wireless communication. Background technique [0002] As an emerging energy technology, distributed photovoltaic technology can simultaneously meet energy demand, reduce greenhouse effect and improve power supply reliability. It is an important direction for the future development of world energy technology. In recent years, my country has successively issued a series of supporting policies to promote the rapid development of the clean energy industry. It is estimated that by 2020, my country's photovoltaic power generation will reach 110 million kilowatts, of which the installed capacity of distributed photovoltaic power generation will exceed 60 million kilowatts. [0003] The current distributed photovoltaic power stations can be solar panel ar...
