Problems solved by technology
[0003] The photovoltaic array requires clean operation and maintenance. For immobile photovoltaic arrays, operation and maintenance robots are often used for operation and maintenance, which is more efficient; It can only operate on a plane with a certain angle range, so it cannot be operated and maintained during the tracking process of the sun-tracking photovoltaic array. If the entire photovoltaic array stops tracking the sun for operation and maintenance, the power generation efficiency will be greatly reduced

The invention provides an operation and maintenance system of a sun-tracking photovoltaic array, which includes a photovoltaic array composed of a plurality of independently operable photovoltaic modules, a control module, a communication module, an operation and maintenance robot, and a computer background; the motors of all photovoltaic modules, The communication modules are all electrically connected to the control module, and the communication modules and the operation and maintenance robot are all connected to the computer background by communication. An operation and maintenance method, comprising the following steps: A. tracking the sun of each photovoltaic module; B. starting the operation and maintenance program; C. returning the current photovoltaic module and the next photovoltaic module to zero; D. operation and maintenance robots on the current photovoltaic module ; E. If the operation and maintenance robot enters the next photovoltaic module, execute step F, otherwise continue to step D; F. The photovoltaic module that has been operated and maintained resumes tracking; G. If all operation and maintenance work is completed, stop the operation and maintenance program, Otherwise, follow steps C to F to carry out the operation and maintenance of the next photovoltaic module. The operation and maintenance system and method can perform normal operation and maintenance work while having little impact on the power generation efficiency of the photovoltaic array.
Description
technical field [0001] The invention relates to the technical field of operation and maintenance of photovoltaic arrays, in particular to an operation and maintenance method for an operation and maintenance system of a sun-tracking photovoltaic array. Background technique [0002] The photovoltaic arrays of photovoltaic power plants mainly include stationary photovoltaic arrays and sun-tracking photovoltaic arrays. The sun-tracking photovoltaic array makes the solar energy directly shine on the photovoltaic array in real time by tracking the maximum movement of solar radiation, thereby increasing the overall power generation efficiency of the photovoltaic array and improving solar power generation. The total power output of the system. [0003] The photovoltaic array requires clean operation and maintenance. For immobile photovoltaic arrays, operation and maintenance robots are often used for operation and maintenance, which is more efficient; It can only operate on a plane...
