Description

Photovoltaic component new energy power data transmission method based on blockchain Technical Field

[0001] The present invention relates to the field of power data technology, and in particular to a method for transmitting new energy power data of photovoltaic components based on blockchain. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at semiconductor interfaces to directly convert sunlight into electricity. It primarily consists of three main components: solar panels (modules), controllers, and inverters, with the majority of these components being electronic components. Solar cells are connected in series and then encapsulated and protected to form large-area solar modules, which, when combined with components such as power controllers, form photovoltaic power generation devices. To meet grid access requirements for photovoltaic power generation, real-time monitoring and information collection are required to ensure system stability. Real-time monitoring data for photovoltaic power generation includes: system operating environment meteorological parameters, primarily temperature, solar radiation intensity (light intensity), wind speed, and severe weather forecasts; and solar panel operating voltage and current. All of this information is collected, processed, transmitted, and stored by the power station monitoring system via communication channels, enabling intelligent monitoring of the entire power station. Patent application number 2021114072397, named "A photovoltaic power generation data acquisition device for power load forecasting", discloses a collection device body, a plurality of heat dissipation holes are opened on the side of the collection device body, and a dust filter is also installed on the side of the collection device body, and the dust filter is arranged opposite the plurality of heat dissipation holes. This invention replaces the heat dissipation mechanism of the traditional collection device to prevent the electronic components inside the device from working in a high temperature environment for a long time, thereby ensuring the stability of the collection device, facilitating the collection of photovoltaic power generation data, and can also clean and dredge the dust filter, ensuring the patency of the dust filter, so that the air inside the collection device body can smoothly pass through the dust filter to convect with the air in the external environment, thereby ensuring the heat dissipation performance of the collection device body. However, this invention does not perform safe processing on the collected photovoltaic data, which is likely to cause data security risks.
