Solar power station power supply system and power supply method

Abstract

The invention relates to a solar power station power supply system and a power supply method, the system realizes that a solar power station supplies power to a power user, the system comprises a photovoltaic panel, a solar panel controller and energy storage batteries, and under the control of the solar panel controller, the photovoltaic panel outputs electric energy to charge the energy storage batteries; the system further comprises a remote monitoring center arranged at the background, monitoring modules arranged on the energy storage batteries and satellite communication modules, the remote monitoring center communicates with the monitoring modules through a satellite communication system, the monitoring modules monitor the energy storage batteries and upload data to the remote monitoring center, and the remote monitoring center generates a control signal and downloads the control signal to the monitoring modules so as to monitor the energy storage batteries. According to the method, under the monitoring of the background remote monitoring center, charged energy storage batteries are transmitted to users in all corners of the world through logistics, and battery discharging is monitored. A power transmission and transformation network is omitted from the power station to the users, the construction cost of the power station and the power utilization cost of the users are greatly reduced, the construction period of the power station is greatly shortened, and meanwhile the defects of an existing solar power station power supply system are overcome.

Description

technical field [0001] The invention relates to a solar power station power supply system and a power supply method. Background technique [0002] As a new type of green energy, solar power plants have been valued by various countries, and many solar power plants have been built in various places. At present, solar power plants mainly have two forms: traditional centralized photovoltaic power station system and traditional distributed photovoltaic power station system. [0003] Among them, the traditional centralized photovoltaic power station system such as figure 1 As shown, its characteristic is that the direct current of the solar panel is boosted by inversion, merged into the power grid, and then stepped down to form the mains to supply power to users. In the power supply process of photovoltaic power stations (solar power stations), it needs to be transmitted through the transmission network, which inevitably causes a lot of losses. In addition, the transmission netw...

Problems solved by technology

The overall construction, use, and maintenance costs of the power station are high; the complexity of operation is relatively high; especially for areas where there is no mature power grid

[0007] Solar photovoltaic power station, power generation is unstable, and the power grid is difficult to absorb

[0008] Distributed solar power plants, due to decentralization, need to establish power plants at specific user terminals, and the management efficiency is not high; the power plants are not large-scale, and the commercial value is relatively low, and relatively speaking, it is difficult to popularize

[0009] Whether it is traditional centralized or traditional decentralized, for backward areas that have not been powered on, wireless communication signals are often not well covered, and it is difficult to achieve intelligent management
