Changzhou State Grain Reserve photovoltaic grid-connected projects smoothly and network

The project is located in Changzhou National Grain Reserve of Hi-tech Zone, Changzhou, Jiangsu Province with a total investment of 24.4239 million yuan. In October 2013, the project was formally inaugurated to disperse the roofs of 17 buildings in the reservoir area of ​​grain reserves. The total capacity Up to 2.5529MWp, the system uses a centralized step-up 10kV and network.

The pursuit of scientific and rational development of solar energy resources, the use of solar photovoltaic power generation, economic development, easing the pressure of conventional electricity supply, beautify the environment play a positive role in supporting and promoting the progress of solar power technology. The construction of the solar power station on the roof of the grain depot and the integration of solar energy components and buildings into a whole form a complete and unified building appearance, which not only saves energy and reduces pollution emissions, but also plays a very active role in saving energy, reducing emissions and protecting the environment. After the completion of the project, the average annual generating capacity is about 2,679,600 kWh, the annual average replacement of standard coal is about 937.89 tons, the annual replacement of dust and soot is 4.82 tons, the average replacement of carbon dioxide is 2,336.67 tons and the annual replacement of sulfur dioxide is 17.42 tons .

Mao Zhen, head of the grain depot project, pointed out that the project has five major advantages:

First, the project main equipment selection has the international advanced level, based on localization, fully demonstrate our country advanced renewable energy development and utilization of technology, equipment localization rate of more than 98%;

Second, optimize the system design, make effective use of the roof of the building, save related resources, maximize installed capacity, maximize power generation and increase return on investment.

Thirdly, the advanced monitoring system and friendly man-machine interface have realized "five remote" (remote communication, telemetry, remote control, remote adjustment and remote control) and laid the foundation for the establishment of a regional smart grid.

Fourth, careful design of the installation of components, to meet the mechanical strength, load requirements of the circumstances, to reduce deadweight and cost; in the design to take into account the relevant climate limit, taking into account the disastrous climate, snow and disaster protection components also have sufficient Consideration;

Fifth, while ensuring the practicality of the project, it should also take into account the display function of new energy technologies. The layout of solar photovoltaic power generation components should be coordinated with the architectural style and the surrounding landscape to embody the concept of ecological architecture and green building.
