Abstract

The invention discloses a photovoltaic floating power station follow-up device and a working method thereof. The photovoltaic floating power station follow-up device comprises a water level monitoring device, a computer, a wireless signal transmitting system, a wireless signal receiving system, a fixing rope, a photovoltaic array, an automatic winding and unwinding device and a traction fixing pile; the signal output end of the water level monitoring device is connected with the computer, and the signal output end of the computer is in communication connection with the automatic winding and unwinding device through the wireless signal transmitting system and the wireless signal receiving system; and the automatic winding and unwinding device is installed on a photovoltaic array, the first end of the fixing rope is connected with the traction fixing pile, and the second end of the fixing rope is connected with the automatic winding and unwinding device. Water level information is obtained through the water level monitoring device, and the automatic winding and unwinding device is controlled according to the information, so that winding and unwinding of the fixing rope are achieved. Therefore, the tension of the fixing rope is consistent under the condition that the water level rises and falls.

Description

technical field [0001] The invention belongs to the field of photovoltaics, and in particular relates to a photovoltaic floating power plant follower and a working method thereof. Background technique [0002] Green development and efficient development will become the future direction of energy system construction. Among the current green power technologies, photovoltaic power generation is one of the most important technologies. It is foreseeable that the construction of photovoltaic power stations will be greatly accelerated. According to the "2019 National Fishery Economic Statistical Bulletin", the national aquaculture area is 7108.50 thousand hectares, of which the freshwater aquaculture area is 5116.32 thousand hectares. Assuming that the available water surface is 1% of it, my country's water photovoltaic can develop more than 38GW. Studies have shown that when the pile length exceeds 8.5m, it is more economical to use floating photovoltaics on water. [0003] Fl...
