Distributed photovoltaic power generation solution

03月31日

The distributed photovoltaic power system mainly uses large scale solar cell array to convert the solar energy into direct current. Through the lightning protection junction box, the multi-channel array is converge into a photovoltaic inverter. The photovoltaic inverters convert the multiple direct current into alternating current, and are allocated to the load by the AC distribution cabinet. Electricity is transported to the power grid; the insufficient part is supplemented by power grids.

Summary

Energy shortage, energy security, the rapid growth of energy prices and environmental pollution have become the primary problems that restrict the social development of many areas. The application and development of global energy are facing a huge crisis. To solve this series of problems, large-scale development and utilization of green energy is one of the important means. On the one hand, the use of green energy can effectively alleviate the problem of energy shortage and the pollution of the traditional ore fuel use to the environment. On the other hand, it can also promote the development of the local economy. Distributed photovoltaic power generation scheme is one of the most important applications of green energy.

  Scheme principle
 
 
 
The distributed photovoltaic power system mainly uses large scale solar cell array to convert the solar energy into direct current. Through the lightning protection junction box, the multi-channel array is converge into a photovoltaic inverter. The photovoltaic inverters convert the multiple direct current into alternating current, and are allocated to the load by the AC distribution cabinet. Electricity is transported to the power grid; the insufficient part is supplemented by power grids.
 
 
 
system composition
 
 
 
Power generation equipment (solar panels and lightning protection confluence boxes).
 
The transformation part (grid connected inverter).
 
Power distribution and metering system (AC distribution cabinet and metering meter system).
 
Energy management system (environment and site detection system, data acquisition and communication unit and background network management system).
 
Scheme bright spo
 
Green, low carbon, pollution-free and noiseless, suitable for construction in industrial parks, office buildings and residential areas.
 
Using high efficiency panel and MPPT inverter system, the solar energy utilization rate is high, and the cost of power generation is reduced.
 
The operation of the grid connected to the public power grid does not require batteries, and the cost of the system is greatly reduced.
 
PV modules are installed on idle roofs, without additional land occupation and low cost of renting roofs.
 
The system adopts hybrid power supply of solar energy and external power grid, namely, the use of power generation and utilization, the high utilization rate of power generation and shortening the investment cycle.
 
Photovoltaic power consumption in situ consumption, reduce 5%-10% transmission and distribution power loss
 
Because solar power is mainly generated during the day, the peak load of industrial parks is also in the daytime, which can effectively reduce the impact of peak load and improve the reliability of electricity consumption.
 
Application scene
 
 
The distributed photovoltaic power generation scheme is mainly for customers in industrial parks or enterprises, business and office buildings with large roofs.
 
 
A distributed photovoltaic power generation system is built on the roof to reduce the power dependence on the grid, while reducing the carbon emissions of the industrial park and creating an eco industrial park. Distributed photovoltaic power generation system will consume the largest amount of electricity locally, and only a small proportion of excess electricity will be transported to the grid. The main reason is that the price of electricity on the Internet is relatively low and the economic efficiency is poor. If all the power generation capacity can be consumed locally, the maximum economic benefits will be achieved. The system can cover 20kW to several megawatts, and can be customized according to the roof area and customer needs.
