Ground photovoltaic power plants refer to solar photovoltaic power plants that are connected to the public grid and share power supply tasks. It is an important development direction for solar photovoltaic power generation to enter the stage of large-scale commercial power generation and become an integral part of the power industry. It is the mainstream trend of the development of solar photovoltaic power generation technology in the world today.

      Ground-based photovoltaic power plants are generally large in scale, lower unit cost, large power generation, and full access to the grid without local consumption, which has a greater impact on the operation of the grid. Therefore, it requires careful management, planned output, and active and reactive output. It needs to cooperate with the power grid, otherwise it will cause the instability of the power grid and ultimately affect the user's use. Therefore, it is necessary to design the boost voltage according to the scale of the power grid. Ground photovoltaic power plants generally include barren mountains, wastelands, deserts, and tidal flats.

      The ground photovoltaic power station is composed of three parts: photovoltaic power generation system, inverter system and grid connection system. The power station basically includes photovoltaic battery packs, photovoltaic square array brackets, DC combiner boxes, DC power distribution cabinets, grid-connected inverters, AC power distribution cabinets, step-up transformers and other equipment, as well as power station monitoring devices and environmental monitoring devices.
