Photothermal power generation or will become the dominant domestic energy in the future

In mid-July, China's first solar thermal power station was built on the grid in Qinghai, indicating that China's self-developed solar thermal power generation technology has entered the stage of primary commercial operation. The reporter learned from the website of the National Energy Administration that this is the first large-scale tower solar thermal power plant in Delingha, Qaidam Basin, with a total installed capacity of 50 megawatts. It is invested and built by Qinghai Zhongkong Solar Power Co., Ltd. The unit to be integrated into the Qinghai Power Grid is a 10-MW project. The second-phase 40 MW CSP project will be fully completed in 2014. It is expected that the annual power generation will reach 112.5 million kWh with a peak efficiency of 24%. Save 39,400 tons of standard coal. In October this year, another demonstration project of solar thermal power generation will also be completed and put into operation in Ningxia Hui Autonomous Region. The total scale is expected to reach 92.5 MW.

In fact, people are not unfamiliar with solar thermal energy. The most intuitive example is solar water heaters. The principle of solar thermal power generation is that solar light is collected by a reflector into a solar energy collecting device, solar energy is used to heat the medium in the collecting device, and the heated medium forms a steam belt to motivate the generation of electricity. The start-up of solar thermal power generation projects dates back to 2011. In the year, China’s first photovoltaic power generation project was tendered for Inner Mongolia 50 megawatt trough solar thermal power station. Datang New Energy Co., Ltd. had a cost of 0.9399 yuan/kWh. Lowest bid.

Through the innovation of solar energy technology and the application of system integration of multiple technologies, solar thermal energy has moved from a single energy source to a multi-energy composite application form. This is also the strategic deployment of the solar energy industry in the outline of the Twelfth Five-Year Plan. People in the industry are unanimously optimistic about the prospects of solar photovoltaic power generation and solar thermal power generation. Experts even believe that in the global low-carbon economy and the new energy revolution, solar thermal power generation may become China’s largest share of the dominant energy in the future. .

Gao Gushi Qu Xueji of the Chinese Academy of Space Science and Technology made a report on the development and prospects of solar thermal power generation and the solar thermal power conversion technology at the Agrion 2013 Energy and Sustainable Development Summit at the end of June. According to Qu Xueji, Although solar-powered photovoltaics have previously been used in the aerospace field, as well as in the photovoltaic and solar cell fields, and before the government has never introduced any policies on solar thermal power generation, but in the last year, the National Energy Administration was based on the 12th Five-Year Plan for Renewable Energy. 》Organized the preparation of the “12th Five-Year Plan for Solar Power Generation”, which clarified the government’s determination to vigorously develop CSP technology. This “Planning” mentions that: In the next 5 to 10 years, the solar power industry will enter a rapid growth period... ...

According to the Energy Outlook report released by the International Energy Agency (IEA) in the next five years, renewable energy sources in the world will grow rapidly, especially in developing countries led by China. The proportion of renewable energy power generation will account for the proportion of global growth. Two-thirds; more than a quarter of electricity will come from renewable sources by 2018.

High Speed Door Motor And Control Box

Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.

About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes.

About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
