Abstract

The invention discloses a system and method for dynamically adjusting distributed photovoltaic data transmission, and relates to the technical field of distributed photovoltaic data transmission. Thesystem comprises a data acquisition device, a wireless private network channel, a wireless access server, an application server, a meteorological information server and the Internet. The system realizes a function that the plant station end data acquisition device carries out data transmission in the daytime stops the data transmission at night, thereby avoiding resource waste, saving the flow charge of a wireless private network card, and thus improving the economic benefit. In addition, the system realizes that the plant station end data acquisition device randomly disperses in a time period(T1+/-t) to initiate communication connection with a main station end server, and avoids high concurrent session impact caused by simultaneous connection of a large number of data acquisition deviceswith the server at the same time, sunrise and sunset time data acquired from the Internet is completely calculated by the trajectory of the earth around the sun and are automatically adjusted along with seasonal changes of four seasons, and the inaccuracy caused by manual time setting is avoided.

Description

technical field [0001] The invention relates to the technical field of distributed photovoltaic data transmission, in particular to a system and method for dynamically adjusting distributed photovoltaic data transmission. Background technique [0002] Distributed photovoltaic power stations refer to the construction near the user's site, and the operation mode is self-use on the user's side, and the excess power is connected to the grid. It is mostly built in rural areas, pastoral areas, mountainous areas, and near developing large, medium, and small cities or commercial areas. To solve the electricity demand of local users, since the distributed photovoltaic power station is to be integrated into the public power grid, it is necessary to collect its relevant power generation data for the dispatching and control of the power supply network. For distributed photovoltaic power stations, due to geographical constraints, the input Low cost, wide coverage, convenient implementati...
