As we all know, the photovoltaic power generation has always occupied an
important share of the solar power generation market, although part of
the solar panel
thermal power generation projects always stick with the technical
route, but it is undeniable, its position and scale photovoltaic power
generation is quite different. The high cost and lack of core
technology, resulting in solar thermal power generation in the country
to promote with the relatively slow pace of industrialization, solar
thermal power projects in the country and far between.
At present, the situation will change.
Solar thermal power generation in the country by virtue of a good match
with the existing power grid, continuous and stable power generation
and peaking power generation capacity advantage, "day and night
continuous power generation, thermal storage, controllable power"
started fast, becoming more heartburn.
Related statistics show
that global grid by the end of 2010 the total installed capacity of
solar thermal power 1.27GW, which occupy a proportion of 35%, Spain 59%;
in the construction of the installed capacity of 1.93GW installed
capacity reached 17.53GW planning , North America accounted for 56%,
Europe accounted for 27%, accounting for 6% of the share in the Middle
East.
In fact, the international market for the layout of the
field of solar thermal power has already started. In 2008, Spain only a
10MW solar thermal power plant to run power generation, but by the end
of 2010, this figure was quickly refreshed to 531.5MW. 2008-2010, the
two years, the Spanish solar thermal power generation total 15.4GWH rise
to 691.5GWH, the growth rate reached 44 times the income of the sale of
electricity has increased significantly, the contribution rate of the
GDP of Spain more than doubled. China in solar thermal power generation
in this area have not yet been realized "zero" breakthrough.
At
present, China has to speed up the planning of the solar thermal power
generation. National Energy Board recently released the "solar power"
12th Five-Year Plan "(hereinafter referred to as the" Plan ") in 2011,
the scale can be almost negligible solar thermal power generation
capacity target of one million kilowatts in 2015, the need to achieve.
Then, the solar thermal power generation will not only achieve a leap
from scratch, future domestic solar power projects three important form
of one, and photovoltaic power generation, distributed photovoltaic
power generation is also subject to state support, its status and
economic benefits is gradually emerging.
At the same time,
China also significantly accelerate the speed of solar thermal power
project approval. June 25 this year, the China Guangdong Nuclear Qinghai
Delingha solar thermal power technology experimental base officially
allowed to start its 50MW trough solar cell
thermal power project is planned to be completed by October 2014, with a
total investment of 20 billion yuan; 15MW tower solar thermal power
projects (863 major scientific and technological demonstration
projects), the planned 2013 start, completed in 2014, an investment of
600 million yuan. Following the July 19, the Institute of Electrical
Engineering, Chinese Academy of Sciences, Beijing Yanqing of 1.5MW tower
thermal power projects successful operation to generate superheated
steam entering the turbine first red run, began to accelerate the pace
of domestic solar thermal power. Tibetan branch, State Power to get the
Shannan Prefecture projects "Lutiao"; 64MW trough solar thermal power
project in Zhangjiakou City, Hebei Province, officially signed the
agreement. The solar thermal power industry in the explosive moment.
Solar thermal industry needs to be started, attracts businesses eager. A
year ago, the solar thermal power generation show was only two trough
vacuum tube products on display, but to the show in March of this year,
has been increased to eight, annual production capacity has reached
400-500MW glass mirror capacity this year bottom up to the equipment the
1200MW trough power plant.
"For now, the global solar thermal
power technology can support the commercialization of demand to meet the
needs of some parts, such as glass mirrors, the transmission system,
the tracker condenser bracket and turbine and other." The Ministry of
Science and Technology of solar thermal industry technology innovation
strategic alliance chairman Wang Zhifeng said in an interview.
Beijing University of strengthening and Energy Conservation, Ministry of
Education Key Laboratory Director Ma Chongfang appeal, in a period of
rapid industrial development, to avoid a warning for a repetition of the
photovoltaic industry overcapacity. MA Chong-fang said: "From the whole
industry chain perspective to support the application of scientific
research, should encourage more enterprises to enter the light and heat
power generation industry, to promote the rapid development of the
industry but Chinese energy layout of the top-level design needs to have
a more in-depth strategic thinking. to discuss what is the energy
mainstream technology, its development prospects how, the direction of
investment and other issues. if not seriously discuss these issues, the
domestic market likely will be putting the cart before the horse. "Ma
Chongfang said," At present, the domestic solar thermal power generation
industry has not yet mastered the core technology, presence of
industrial blind expansion, industry vicious competition, and other
issues. "
Hanqing Hao, general manager of China Guangdong
Nuclear Solar, solar thermal power generation industry is indeed facing
four major problems. The first is the lack of core equipment and key
accessories actual project run test; followed by systems integration
experience with the development, design, construction, commissioning,
operations technical capacity of the whole process extremely scarce
talent; Third, the lack of detection platform and standard system. In
addition, the lack of the whole process of design, construction,
commissioning and operation of the standard system; climate and
environmental conditions are relatively more complex and poor, the lower
the average temperature of the light resource-rich regions, dust,
altitude, high winds, water resources are relatively scarce.
As
of 2011, the past 20 years has been built around the world of light and
heat only 1.35GW, developed solar energy in our country, "the 12th
Five-Year Plan", 1GW in 2015 to complete the construction of the size of
the light and heat, with a time of more than three years to catch up
with sum of about 20 years around the world, the size of the market
should not be overlooked. Wang Zhifeng, said: "The parties to force the solar charge controller
thermal power industry comes as normal, but also need to have a
guarantee of quality supervision system and product, in order to avoid
the chaotic state of the industry into the disorderly competition."
