I. Centralized photovoltaic power station overview
Concentrated photovoltaic power station is the state use of desert, concentrated proposal of large photovoltaic power station, power generation directly into the public grid, access to high-voltage transmission system to supply long-distance load.
Second, centralized photovoltaic power plant structure
Three, DC converter box
In the solar photovoltaic power generation system will be used to the sink box, also known as solar sink box, solar photovoltaic sink box, photovoltaic array lightning protection sink box, solar power sink box, photovoltaic power generation sink box, photovoltaic lightning protection sink box.
In the solar photovoltaic power generation system, in order to reduce the solar photovoltaic cell array and inverter between the connection line used to the sink box. Combined with years of experience in lightning protection system design, developed a variety of open number sink box. Users can connect a certain number of photovoltaic cells with the same specifications in series to form a photovoltaic array, and then connect several photovoltaic arrays in parallel to the photovoltaic convergence lightning protection box, after convergence in the photovoltaic lightning protection convergence box, through the controller, DC distribution cabinet, photovoltaic inverter, AC distribution cabinet, supporting the use of a complete photovoltaic power generation system to achieve grid connection with the utility. In order to improve the reliability and practicality of the system, the PV lightning protection sink box is configured with a special DC lightning protection module, DC fuse and circuit breaker, etc., to facilitate the user to accurately grasp the working conditions of the PV battery in a timely manner and ensure the effectiveness of the solar PV power generation system.
DC sink box is to reduce the photovoltaic cell array access to the inverter connection, optimize the system structure, improve reliability and maintainability. While providing the sink lightning protection function, it also monitors the photovoltaic cell panel operation status.
