Water surface floating type photovoltaic power station overall stability control system

Abstract

The invention discloses a water surface floating type photovoltaic power station overall stability control system. The water surface floating type photovoltaic power station overall stability controlsystem acts on stable units of a photovoltaic array in the water surface photovoltaic power station, and a shore fixing device and an underwater anchoring device are arranged aiming at each stable unit; the shore fixing devices are arranged on the sides, close to a shore, of the stable units, and each stable unit comprises a stable unit connecting point, a mooring rope and a shore fixed point; theunit connecting points which are fixed to the stable units are connected with the shore fixed points which are fixed on the shore through the mooring ropes; and the underwater anchoring devices are arranged on the side, away from the shore, of the stable units; and each underwater anchoring device comprises a stable unit anchoring point, an anchoring rope and an anchoring block, and the stable unit anchoring points which are fixed to the stable units are connected with the anchoring blocks which are arranged in seawater through the anchoring ropes. According to the water surface floating typephotovoltaic power station overall stability control system, overall stability is good, the effect of the wind wave load can be resisted, deflection of the photovoltaic array is prevented, a floatingbody is uniformly stressed, stress concentration of the connecting points is avoided, and normal and efficient operation of a photovoltaic power generation system are ensured.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to an overall stability control system for a floating photovoltaic power station on the water surface. Background technique [0002] In recent years, the number of water surface photovoltaic power plants at home and abroad has increased significantly. Floating water surface photovoltaic power plants have become the most popular form of water surface photovoltaic power plants in the market due to their advantages such as wide application range, strong hydrophilicity, and high power generation efficiency. [0003] The surface floating photovoltaic power station is suitable for deep waters, but because there is no guarantee of a fixed foundation, it is easily affected by complex environmental factors and prone to large deviations. Therefore, in order to ensure that the floating photovoltaic power station on the water surface can withstand a certain degree of wind ...

AI Technical Summary

Problems solved by technology

In the existing stabilization system, the anchor ropes are generally directly connected to the lugs of the supporting buoys of the photovoltaic power station. The stress is too concentrated, which may easily lead to the breakage of the lugs and the failure of the buoys; it is difficult to ensure the same length for the construction of multiple anchor ropes. When playing a stabilizing role, there is often a phenomenon of uneven force on each anchor rope, resulting in excessive stress and stress concentration on individual anchor ropes; it is difficult to adapt to the large water level changes between the dry season and the wet season in the water area, and the operation of floating photovoltaic power plants on the water surface Vulnerable; piling is expensive to stabilize the array
