The method comprises the following steps: carrying out block division on a photovoltaic array of a water surface photovoltaic power station to generate blocks; selecting a sample component in each block, and obtaining a sample azimuth angle and a sample inclination angle of the sample component; obtaining a block azimuth angle and a block inclination angle of a block where the sample assembly is located according to the sample azimuth angle and the sample inclination angle, taking the block azimuth angle and the block inclination angle as characteristic parameters, clustering all blocks to generate a sub-array, and determining the capacity of the sub-array, the sub-array azimuth angle and the sub-array inclination angle; and inputting the sub-array capacity, the sub-array azimuth angle and the sub-array inclination angle into a photovoltaic power generation capacity simulation model for simulation. The influence factors of hydrological and meteorological parameters changing along with seasons are considered, so that the accuracy of simulation input parameters is higher, and the accuracy of a simulation result is improved; and the similar blocks are combined into a subarray for simulation, so that the simulation efficiency can be improved, and accurate and efficient simulation of the water surface photovoltaic power station is realized.

Description

technical field [0001] The present invention relates to the field of photovoltaic technology, in particular, to a simulation method, device and system for a water surface photovoltaic power station. Background technique [0002] Two important parameters for power generation capability simulation are the azimuth and inclination of the PV modules, which determine the amount of solar radiation received by the PV modules. For the water surface photovoltaic power station, due to the influence of the changing water flow and wind, the azimuth and inclination of the photovoltaic modules are also constantly changing, which is quite different from the ground photovoltaic power station. Therefore, the water surface photovoltaic power station cannot be the same as the ground photovoltaic power station. The simulation is performed according to the preset azimuth and inclination. SUMMARY OF THE INVENTION [0003] The problem solved by the present invention is how to obtain the azimuth ...
