The advantages of my country's development of floating photovoltaic power stations
In 2014, the cumulative installed capacity of photovoltaic power generation in my country was 28.05 million kilowatts, and the cumulative power generation was 25 billion kWh. Among them, the photovoltaic power plant is 23.38 million kilowatts, the distributed is 4.67 million kilowatts, and the new installation capacity is 10.6 million kilowatts, accounting for about one -fifth of the world's new installed capacity. Uniformly increases by 10 million kilowatts annual.(Lithium - Ion Battery Equipment)
The new installation capacity in the central and eastern regions reached 5.6 million kilowatts, accounting for 53%of the country, of which 1.52 million kilowatts were added, second only to the Inner Mongolia Autonomous Region; Inner Mongolia, Qinghai, Gansu and Ningxia are large.
The newly added panel power station takes a large -scale photovoltaic power station as an important upward driving force. In the future, with the continuous innovation of photovoltaic power generation models, the distributed scale is expected to rise steadily. According to the National Energy Administration plan, the 2015 National Photovoltaic Annual Plan was added by 15 Gaval, of which 8 Gaval was gathered, and 7 Gava was distributed (of which the roof distributed distribution was not less than 3.15 Gava). , Tianjin, Shanghai, Chongqing and Tibet, without discarding light, there is no upper limit of development.
1. There are more people in my country, and the development of the water plants can save the use of land. One of the disadvantages of photovoltaic power stations is that the energy is scattered and covers a large area. The photovoltaic power plant is permanently occupied, and the large -scale photovoltaic power plant needs to occupy a large land area. According to the book "Construction Design and Maintenance of the Solar Photovoltaic Power Generation System", theoretically, it covers an area of 100 square meters per 10 kWh photovoltaic power generation system, which is equivalent to the unit. A kilowatt is 10 square meters.
However, in order to reduce the shadow effect and reduce the loss of power generation, there should be a certain interval between the battery plates, thereby further increasing the area occupied. The entire photovoltaic power station covers an area of 30 square meters. 30 square meters.
2. The evaporation volume of northern my country is greater than the rainfall. Development of the surface photovoltaic power plant can reduce the amount of evaporation of the water surface. In the past 40 years, the amount of precipitation and evaporation in the arid and semi -arid areas in my country has decreased, but the reduction rate of precipitation is greater than the evaporation volume. The imbalance of water revenue and expenditure causes the dryness of the climate. The surface photovoltaic power plant can reduce water evaporation due to covering a large amount of water surface.
3. There are 32,000 kilometers of long coastline in my country, and it has greatly developed the topographic advantages of the photovoltaic power plant. my country has nearly 3 million square kilometers of sea areas. The coastline is divided into the mainland coastline and the island shoreline, of which 18,000 kilometers of the mainland coastline. The starting point of its north is the Yalu River Estuary, and the end of the south is the Beilun River. The development of the surface photovoltaic power plant along the line not only has low operating difficulty coefficients, but also provides power support for developed economic areas along the route.
4. There are 86,000 reservoirs in my country (as of the end of 2012), the total reservoir is 6924*108 cubic meters, and the total area of the nation's reservoir surface is 25619,000 hectares, which is 38.429 million mu. Develop a prerequisite for the surface photovoltaic power plant. The surface of the reservoir is important for water storage, power generation, irrigation, breeding, landscape travel and ecological protection.
There are more than 90%of the existing reservoir surfaces for breeding. The actual breeding area accounts for only 78%of the total area of total area, and the unit area output is generally low, but the surface photovoltaic power plant will not affect the development of the breeding industry.
5. There are many lakes in my country, with a total area of 91,000 km2 and more than 2,700 with an area of more than 1,000 square meters.
6. The surface photovoltaic power plant is very friendly to the environment. The equipment such as the float stand can be recovered 100%, and the solar power generation efficiency is high.
In summary, my country should vigorously develop the surface photovoltaic power plant, while improving economic benefits, maintaining the healthy and harmonious development of the environment.
