Method for designing water surface floating type photovoltaic power station anchoring systems

Abstract

The invention discloses a method for designing water surface floating type photovoltaic power station anchoring systems. The method includes steps of 1), collecting meteorological and hydrological data and geological exploration data which are related to projects; 2), preliminarily determining the sizes of anchoring units and the quantity of anchoring points on each side according to the scales ofwater surface photovoltaic power stations and the meteorological and hydrological data; 3), building hydrodynamic models, simulating mooring force conditions of anchor lines under stormy wave and current conditions by the aid of hydrodynamic software and acquiring mooring force of the anchoring units and wave force; 4), checking the internal strength of arrays according to the mooring force and the wave force which are computed at the step 3), carrying out a step 5) if requirements are met by the strength, or carrying out the step 2) if the requirements are not met by the strength; 5), designing steel supports, the anchor lines and anchor blocks according to mooring force computation results and checking the strength; 6), checking extreme working conditions for the anchoring arrays according to extreme working conditions; 7), combining site conditions of the projects with one another and carrying out wind-resistant and wave-proof design for the integral anchoring arrays.

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
