Data collection and connection of grid-connected power generation, electricity meters and inverters in new energy photovoltaic power stations to the cloud platform

A grid-connected photovoltaic power generation system refers to a system where the direct current generated by solar cells using solar radiant energy (i.e., the "photovoltaic effect" of solar cells) is converted into alternating current through a grid-connected photovoltaic inverter and transmitted to the power grid. In essence, it is a power station that generates electricity using solar energy. Compared with power station systems that generate electricity through traditional energy sources such as coal, oil, and natural gas, grid-connected photovoltaic power generation systems have the advantages of being renewable and non-polluting. Photovoltaic modules generate current through the photovoltaic effect, which is then inverted by an inverter to convert direct current into alternating current. After that, the alternating current is boosted to 10kV through a photovoltaic booster and connected to the 10kV busbar of the grid-connected cabinet in the electrical room for grid connection. The electricity meter protocol supports DLT645-1997/2007 and DLT698.45 protocols. The acquisition gateway supports intelligent lightning protection combiner boxes, DC lightning protection distribution cabinets, inverter systems, AC lightning protection distribution cabinets, transformers, system power distribution, and box-type transformers. Relying on rich experience and resources in electrical system scheme integration and supply chain integration, the product supports the electric power E-file standard, supports the IEC61850 protocol, is compatible with inverter components and horizontal isolation equipment from various manufacturers as well as high and low voltage distribution cabinets, and can be connected to various power monitoring systems and power dispatching systems, enabling the rapid implementation of photovoltaic power station projects.
