Photovoltaic power station refers to a photovoltaic power generation system that uses solar energy and special materials such as crystalline silicon panels, inverters and other electronic components to form a power generation system that is connected to the power grid and transmits electricity to the power grid. Photovoltaic power stations are the green power development energy projects that the country encourages the most.
Photovoltaic power generation generally includes centralized photovoltaics, distributed photovoltaics, etc.
What is a centralized photovoltaic power station
A centralized large-scale grid-connected photovoltaic power station refers to a large-scale photovoltaic power station that is built in areas with large areas of unused land such as deserts, Gobi, water, deserts, mountainous areas, and relatively stable solar energy resources. The power generation is directly connected to the public power grid and connected to the high-voltage transmission system. The power grid is uniformly allocated to supply power to users. The grid-connected voltage is generally 35 kV or 110 kV.
The land nature requirements for centralized photovoltaic power stations are relatively high. At present, common centralized power stations usually use deserts, mineral wastelands, Gobi, saline-alkali land, wasteland, tidal flats, etc. The power station investment cost is high, the construction period is long, and the land area is large.
Advantages of centralized photovoltaic power stations
1. More flexible site selection and operation mode;
2. Low operating cost, easy to centrally manage;
3. The stability of photovoltaic output has increased, and the positive peak-shaving characteristics of solar radiation and power load are fully utilized to play a role in peak reduction.
Installation process and precautions
Preliminary preparation: including site selection, design, and capital preparation. When selecting a site, factors such as lighting conditions and land use should be considered.
Installation and construction: including bracket installation, panel installation, cable laying, etc. Safety and quality should be paid attention to during construction.
Post-commissioning: After the installation is completed, the system is debugged to ensure the normal operation of the photovoltaic power station.
The importance of operation and maintenance management
Daily maintenance: Regularly check the status of the equipment and deal with minor problems in a timely manner.
Troubleshooting: When a problem occurs in the system, it can be quickly located and resolved.
System optimization: Adjust system settings according to operating data to improve power generation efficiency
