Description

Channel main floating body and supporting floating body coupled water surface photovoltaic power generation system and method

technical field

The invention relates to the field of photovoltaic power generation, in particular to a water surface photovoltaic power generation system and method coupled with a channel main floating body and a supporting floating body.

Background technique

As an ideal clean energy for human beings, solar energy has made important contributions to building a low-carbon society. With the continuous maturity of photovoltaic technology, photovoltaic power generation has gradually become the main force of new energy power generation. However, due to the large area occupied by photovoltaic power stations, land resources cannot be rationally allocated. Therefore, the use of water surface space to build floating photovoltaics is an optimal use of resources. It can not only make rational use of land resources, increase power generation, but also protect the water environment and reduce floating dust.

The surface floating photovoltaic power station uses floating tubes, floating tanks, etc. as floating bodies, and uses itself as a support or builds a support on the floating body to support the photovoltaic modules at a certain angle to achieve power generation. Since the surface floating photovoltaic power station is built to float on the water all year round, the waterproof and anti-corrosion requirements for the floating body and support materials are relatively high. Development costs are high. This has become a bottleneck to curb the promotion and development of floating photovoltaic power plants. In addition, most of the floating photovoltaic power stations that have been built so far are located in still water areas such as inland lakes, reservoirs, and fish ponds. For floating photovoltaic power stations in rivers, seas and other areas, how to ensure the safety of photovoltaic power stations under the condition of flowing water? Stability and security are also very critical issues.

At present, there are already many patents on the floating body of the floating photovoltaic power station on the water surface, but most of them have not solved the above-mentioned problems. For example, CN103516298A discloses a floating body photovoltaic system for calm water surface, which uses a floating box and a bracket to support the photovoltaic module on the water surface. However, this patent only provides the conceptual design of the floating body, and does not describe in detail important features such as the connection mode, stability, and maintainability of the floating body; CN105119558A discloses a modular floating photovoltaic array, which uses a connection mechanism installed on the floating body to support components, but this patent does not consider the maintenance channel of photovoltaic modules, which is not conducive to the later maintenance of the power station; CN105790682A, CN204886790, CN204947966U, CN204947983U, CN105162399A, CN205105144U, CN204836054U and other patents disclose similar water surface photovoltaic power generation systems, all of which combine floating bodies and supports to form a whole The supporting structure of photovoltaic modules is optimized, and pedestrian passages are designed for easy maintenance. However, in these patents, each photovoltaic module occupies an average of 3 or more floating structures, which increases the cost of photovoltaic power plants and is not conducive to the commercialization of floating photovoltaic power plants. popularization and application; the Chinese invention patent with application number 2016103175562 discloses a floating body of an L-shaped water surface photovoltaic power generation system. overall stability of the system. However, the position of the steel in this patent is near the water surface, which is easy to cause corrosion damage to the steel structure, and the aisle of the floating body structure is thin and the interval is large, which is not easy to construct and maintain; The component supporting floating body and the second component supporting floating body are connected to each other to form the floating body and channel of the surface photovoltaic power station, and the photovoltaic modules are fixed on the first component supporting floating body by rail-type clamps. However, the first component of this kind of photovoltaic floating body supports the floating body with a large volume and high manufacturing cost; in the connection method of the connecting ear, the connecting ear is used as a stress concentration point, which bears all the stress between the floating bodies and is easy to be damaged; the designed inclination angle of the floating body is low, Difficult to apply to high-dimensional areas; an average of 16 components need to be installed for each photovoltaic module, the installation process is complicated, and the labor cost is high; The components occupy about 20.8kg of the total weight of the floating body, and the cost is relatively high.

At present, the construction cost of photovoltaic power stations on water surfaces is relatively high, and installation on water is more difficult than on the ground. Therefore, how to simplify the floating body structure, reduce the cost of floating bodies, components and installation, improve the maintainability of photovoltaic power stations, and reasonably set up cable channels is the current floating photovoltaic system on water. Issues that need to be considered and resolved in the sustainable development of power stations.

Buoyancy calculation:

In this example, a polysilicon module with a power of 260Wp and a size of 992mm×1650mm is used, and its carrying capacity is calculated as follows with 88 photovoltaic modules as a unit:

The total load of the surface photovoltaic power generation system:

Photovoltaic module: 20Kg/block × 88 = 1760kg;

Floating body weight: main floating body: 7.86Kg/block × 117 blocks = 919.62kg; component support floating body: 6.77kg/block × 104 blocks = 704.08kg; walkway board: 10kg/block × 16 blocks = 160kg;

Installation and maintenance personnel: 8 persons × 75Kg/person = 600Kg.

Considering the safety factor of 2.0, the total load is about 8287.4kg.

The total buoyancy of the surface photovoltaic power generation system:

According to the buoyancy formula, the main floating body can provide buoyancy of 147kg/block, and the component support floating body can provide buoyancy of 68kg/block, then the total buoyancy is: 147kg/block×117 blocks+68kg/block×104 blocks=24271kg.

Therefore, this embodiment can fully guarantee the buoyancy requirement of the water surface photovoltaic power generation system.

Workload calculation for installation parts:

In this embodiment, 88 photovoltaic modules are used as a unit to calculate the number of installation parts as follows:

Main floating body connecting bolts: 9 rows×24/row=216

The connecting bolts between the main floating body and the component supporting floating body: 9 rows×52/row=468

Component limit bolts: 88 pieces x 2 pieces/piece = 176 pieces

The total number of installation parts is 860 pieces, and the average workload of floating body and module installation parts is about 9.77 pieces per photovoltaic module.

Compared with the patent US2014224165A1, the workload per installation of photovoltaic modules has decreased by about 6 pieces. Therefore, this embodiment can reduce the workload of the installation parts and save labor costs.

Float cost calculation:

In this embodiment, 88 photovoltaic modules are used as a unit to calculate the floating body material required for a single photovoltaic module. The values of the wall thickness of the floating body and the height of the main floating body are similar to those of patents US2014224165A1 and CN105186968A, respectively:

Wall thickness of floating body: 5mm on the upper surface and 3mm on the rest

Float height: 200mm

Materials required for a single float:

Main floating body: 8.67kg/piece, component supporting floating body: 6.77kg/piece

The floating body material required for each photovoltaic unit is: 117 x 8.67kg/pc + 104 x 6.77kg/pc = 1718.47kg

The average material required for a single photovoltaic module is: 1718.47kg/88＝19.5kg

Compared with patents US2014224165A1 and CN105186968A, a single photovoltaic module saves about 1.3kg of materials. Therefore, this embodiment can reduce the consumption of materials and save costs.
