Abstract

The invention provides a photovoltaic string azimuth angle determination method and device and electronic equipment, and the method comprises the steps: obtaining a power generation performance data sequence of a photovoltaic string and sun angles at different moments, and the power generation performance data sequence comprises power generation performance data of the photovoltaic string at different moments; determining a maximum data moment corresponding to maximum power generation performance data in the power generation performance data sequence, and establishing an objective function according to the sun angle and the power generation performance data at each moment; and determining the string azimuth angle of the photovoltaic string according to the maximum data moment and the objective function. According to the technical scheme, the workload and labor cost for determining the azimuth angle of the photovoltaic string are reduced.

Description

technical field [0001] The present invention relates to the technical field of photovoltaic power generation, in particular to a method, device and electronic equipment for determining the azimuth angle of a photovoltaic string. Background technique [0002] In a photovoltaic power station, the azimuth angle of the photovoltaic string has a crucial impact on the power generation of the photovoltaic power station. The azimuth refers to the angle between the vertical plane of the PV string and the south, north, east, or west directions. Due to the influence of terrain and construction reasons, the azimuth angles of different PV strings may be different. However, if photovoltaic strings with different azimuths are connected in parallel, there will be a parallel mismatch, which will affect the power generation of the entire inverter. Therefore, if the azimuth angle of the photovoltaic string can be detected in time, and when the azimuth angle of the photovoltaic string is incon...
