Design method of anchoring system for floating photovoltaic power station on water surface

Abstract

The invention discloses a design method for the anchoring system of a floating photovoltaic power station on the water surface. The method includes the steps of: 1) collecting meteorological, hydrological and geological survey data related to the project; 2) initially determining the anchoring unit according to the scale of the photovoltaic power station on the water surface and the meteorological and hydrological data Size and the number of anchor points on each side; 3) Establish a hydrodynamic model, use hydrodynamic software to simulate the mooring force of the anchor rope under the condition of wind, wave and current, and obtain the mooring force and wave force of the anchor unit; 4) According to step 3 ) calculate the mooring force and wave force, check the internal strength of the array, if the strength meets the requirements, then enter step 5), otherwise return to step 2); 5) according to the mooring force calculation results, carry out steel support design , anchor rope design and anchor block design, and check the strength at the same time; 6) According to the limit working conditions, check the limit working conditions of the anchoring array; 7) Combined with the project site conditions, carry out windproof and wave proof design for the anchoring array as a whole .

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to a design method for an anchoring system of a floating photovoltaic power station on water. Background technique [0002] When my country developed photovoltaic power generation in the early days, affected by factors such as sunshine resources and land rent, the large-scale photovoltaic ground power stations built were mainly concentrated in the western regions. However, these regions have insufficient local consumption capacity for photovoltaic power. The phenomenon is serious. However, in the eastern region of my country, where there is a large demand for electricity, there is less idle land and the cost of land use is relatively high, which is not suitable for the development of large-scale ground photovoltaic power plants. In contrast, the eastern region is rich in water resources, with many lakes and reservoirs, and has the advantage of large-scale devel...

Problems solved by technology

At present, most of the anchoring methods commonly used in engineering are the product of experience, and no standardized and systematic design method has been formed; the principle of anchor point arrangement and the basis for the arrangement quantity have not been given; the calculation of the mooring force of anchor ropes under different working conditions is lacking data, unable to verify the effectiveness of the anchoring system

There are no similar patent documents at home and abroad, so it is very important to propose a standardized and systematic design method to guide the anchoring system design of water surface photovoltaic arrays
