Difficulty: Power bottleneck transmission

From the introduction Battelle, although wind energy in Inner Mongolia is rich in resources, but wind power accounts in Inner Mongolia for the overall proportion of electrical energy does not exceed 15%, mainly because of technical limitations of current grid, to take “Wind & Fire bundled” approach to art, resulted in the wind farm can not be at full capacity.

Lack of capacity of the transportation system is currently the province is facing many choices of wind development. Li Jianhua, secretary of the city of Jiuquan in Gansu province in the chain the China Securities newspaper reporter to wind farms in Gansu, for example, according to the plan in 2010, the base of installed wind power capacity reach 5.16 million kilowatts in 2015 will reach 12.71 million kilowatts. However, as the site of the construction of power grid wind energy are far behind in energy development, the provision of other peak power is also behind the construction of the development of wind energy, which leads directly to the idling of the wind turbine can not access the network game.

The solution: the development of thermal power peaking Support hp Pavilion dv4 battery  hp Pavilion dv6 battery

Li Jianhua proposal to develop wind energy in areas that require integration of the energy reaches a peak, and now the most reliable power is also a peak thermal energy. “In densely populated areas of the development of thermal energy, wind energy in the development of thermal energy. The biggest advantage is to reduce the transport of coal in situ digestion and transportation of coal it itself is energy intensive and exclusive carbon construction in in situ is a relatively low carbon The. “Jianhua Li said that the resolution of wind power key to the problem of instability in the regulation of the power reaches its maximum.

Tao Jianhua further suggested that because the earth winds rich in mineral resources, so it may be to consider the development of certain sectors of high energy, thereby reducing the external power, reducing power losses in Sinotrans. “This relates to the industrial plan, taking into account the rationality of the industrial distribution and local economic development, but also be useful to provide comprehensive industrial countries and reduce carbon emissions.

Nuclear Power: the inner penetration of breakthrough

As photovoltaics, wind energy peaked bottlenecks are subject to restrictions, which also makes nuclear power as a new energy domain of a heavy head. In the current power structure, the proportion of coal in 75% of long-term, nuclear energy accounted for only 1.1%, with the global nuclear power generation capacity by 16% of the total proportion by far.

Demonstration Area: Jiangxi led by transfer of nuclear energy

China Securities Journal Reporter interviewed during two sessions, development director of the Jiangxi Province and Reform Commission Yao Mu-gen, “he said, the state planned to build two nuclear power plants in Jiangxi province, may be seen in the inland province of Jiangxi is no doubt that the development of nuclear power in key provinces and in the nuclear Pengze are likely to become a pioneer in the nuclear path. TravelMate 290 battery BATBL50L6

“Nuclear Development Plan long-term (2005-2020)” shows that by 2020, nuclear power and run to reach 40 million kilowatts of installed capacity of fighting in the construction of nuclear power capacity should be maintained at approximately 18 million kilowatts. In fact, this planning is obviously too conservative. The industry generally agreed that by 2020, China’s operating installed capacity of nuclear power will reach 60 million kilowatts while in the construction of nuclear capacity in more than 1000 million kilowatts.

Consequently, the debate is who will become China’s first nuclear power route has quietly begun the competition. Jiangxi Nuclear Power Investment Co., Ltd. February 23, said the fight for the first channel of the province Peng nuclear power projects in China began to build nuclear plants and the projects approved during the year, and construction. In this regard, Yao Mu-Gen, said, Jiangxi is in fact central to the development paths of nuclear energy, primarily in the location decisions of Jiangxi. As the distance between the Yangtze River Delta, the Pearl River Delta near the development of nuclear energy in the province of Jiangxi, the power supply to the surrounding areas have played a role in the protection and regulation is Jiangxi to protect electricity supply but also Guangzhou, VGP-BPS9A/B VGP-BPS13/S VGP-BPS10 Shanghai, Xiamen and other coastal cities of the east, coupled with resource constraints in Jiangxi clean coal, 70% coal must rely on outsourcing.

Yao Mu-gen introduction Road, Jiangxi Province, over 80% of the current supply of electricity is based on thermal power, only 300 million kilowatts of installed hydroelectric power, due to the distribution of the scattered energy efficiency to play is not high. Under the plans, after 2025, nuclear power will replace the conventional thermal current, which becomes the main source of energy supply in the province of Jiangxi.

Difficulty: the object level of technological research and development

“The fate of the great problems of nuclear development is the lack of technical reserves.” Member of National Committee of CPPCC and former former general manager of Datang Power Group Zhairuo Yu told the China Securities Journal that he thought China currently has six nuclear power plants 11 units of production, 5 types of reactor types, affecting the level of R & D and manufacturing capacity of equipment, increased cost of operation and management. Compared with China has also begun to develop nuclear energy in South Korea, began to take nuclear energy construction projects abroad, China’s nuclear technology level of over-reliance on foreign technology.

The solution: competition and balance

Interestingly, the same technology for domestic nuclear power, concern about excessive external dependence, different people have given suggestions. Zhai Ruoyu that investors are too few to monopolize the service, leading to the slow progress of technology of nuclear energy in China, the cost remains high. “The lack of competition will result in the closure of nuclear plant construction, operating system, the degree of market oriented low specialization. Zhai Ruoyu proposed liberalization of Nuclear Energy Generation Group power investment Important operating nuclear power controlling owners to achieve diversity. At the same time to break the closed system, nuclear energy, to promote the market sector of nuclear energy directed towards specialization and achieve nuclear design, engineering and R & D and exploitation of nuclear separation as soon as possible, two, three neutral, not affiliated with any group of power generation and focused on the design of ‘Nuclear Energy Nuclear Engineering R & technology development and general contracting business for companies operating nuclear benefits of professional design engineering and other services.

Member of National Committee of the CPPCC Guangdong Nuclear Power Group, Qian Zhimin, Chairman believes that to address the nuclear technology is the key behind the country’s nuclear industry is not enough to constitute a joint force. He suggested those developing countries’ energy and new energy development plan “must be accompanied by a parallel development” of energy and a new plan for energy innovation, and creating energy R National & D institutions, and better use of institutions for R & D exist. He presented Road, domestic R & D projects in the energy sector, 11 million people engaged in research and development of nuclear reactors with more than 20, lack of communication between each other and do not form a coherent line of research is lagging behind technology of nuclear energy in China is. He also said that because China is now the largest market for new energy and new energy fields in the world is not yet a recognized power, so in the next 10-15 years will be China to become the new power in the history of energy innovation and opportunity.

In recent years, grid-connected photovoltaic capacity installed primarily in three countries: Japan, Germany and the United States, mainly for PV in these countries are more favorable policies, but in recent years, d other countries like Spain, Korea, Portugal and other countries have successively published a series of policies to encourage solar photovoltaic applications. PA3396U-1ACA PA3467U-1ACA PA3282U-1ACA

In recent years, with solar photovoltaic power generation, the pace of development accelerates, the developed countries to emerging trends and network capacity growth of more and more apparent. With the cost reduction of PV power generation costs and increase energy, one day, the cost of the cost of photovoltaic electricity will be fairly traditional. At that time, the photovoltaic enter the stage of commercial demand.

The EU has become a global network of solar photovoltaics connected dominant region, the future of the world’s leading grid solar photovoltaics connected to development. Can be predicted, the European Union production of photovoltaic solar energy will have a large scale in 2010-2020 and gradually the energy market dominance, .2020-2030 years, close to the price of peak electricity market In the years 2020-2040 the average price close to the electricity market.

2 systems connected to the principle of power generation and composition ofPA3083U-1ACA PA3282U-2ACA

Through solar cells (also known as photovoltaic cells) to solar radiation is converted to electrical energy production known as the cell system for solar energy (also known as solar photovoltaic systems ). Solar energy is solar energy directly into the methods of conversion of electrical energy, including photovoltaic, photochemical production, detection optical output power. Solar photovoltaic system to produce energy using photovoltaic solar cells convert sunlight directly into an electric energy radiation is a new generation system. Solar photovoltaic ground modes of operation of power generation system can be divided into off-network operation and networking to run two major categories.

Energy conversion devices for solar photovoltaic cells, also called photovoltaic cells. Photovoltaic cells on the base unit system, which is a unique string of solar cells, and packaged in components, as required by the system, solar cells, then the series and in parallel and installed in the portion of constitute a solar generator (PV Array). In photovoltaic cells on both sides leads to electrodes, and connected to the load, then outside the circuit, current flows through the brilliance of Health to obtain the output power, so as to cells Solar convert solar energy directly into electrical energy. PV system energy production is the use of photovoltaic cells that convert sunlight into electrical energy and the matrix stored on the F3172A PB995A 338794-001 battery system or used directly for the cost of renewable energy installations. The operating principle is: the day, consisting of photovoltaic cells to receive the sunlight is converted into electrical energy, part of the supply or alternating current workload, another part of the electricity excess can be anti-anti-LED battery charge at night or on rainy days, components of photovoltaic cells can not operate, battery or AC to DC load of work.

Systems photovoltaic power generation, including photovoltaic panels is generally devices DC-DC conversion, storage devices, device output power conversion, the controller 5 majority, shown in Figure 1.

(1) solar panels: Photovoltaic solar panels are the basic unit of the system, when all the lights when the battery, the battery absorbs light energy and produce the photovoltaic solar energy into DC may be.

(2) Solar Controller: Due to an array of photovoltaic cells have a strong nonlinear characteristic in order to ensure the array of photovoltaic cells in the light of day and the temperature is always the maximum power output corresponding generally the introduction of point photovoltaic maximum power tracking (MPPT-Maximum Power Point Tracking) control. Inspiron 1420 battery Inspiron 5100 battery

(3) Devices for DC-DC conversion: through the circuit devices power control in hand and turn up, will the network output of photovoltaic cells in a hollow high voltage direct current, DC voltage step – up for the DC-AC inverter to create the preconditions to be able to ensure that a wide range of variation of voltage DC input, output stability under high voltage direct current, while the point maximum power tracking control functions.

(4) Inverter: The inverter is part of photovoltaic panels and batteries to provide a low voltage DC into 220 volts AC reverse supply AC load to use.

(5) devices for energy storage: batteries are generally provided by a number of lead-acid batteries throughout the series and in parallel with his ability should be chosen with photovoltaic cells to match the capacity of the table . The main role of this part of the array of photovoltaic cells is sent directly to the shop in DC for charging to use. Inspiron 5150 battery Inspiron 700m battery

At present the system of solar photovoltaic power generation can be divided into three categories, off-grid photovoltaic power systems, storage systems connected to PV, and the first two hybrid systems. Solar cell’s electrical system and energy production is the use of the theory of the photovoltaic effect is made, it is the direct conversion of solar energy into electrical energy system generating electricity. It is the main square by the solar cells and inverters from both sides.

The solar system of energy production through solar energy into electricity without energy storage battery, inverter grid-connected directly into the grid provided. Home grid-connected PV system, the principle illustrated in Figure 2, it is sunny during the day when the sun solar panels resulting from the dc / ac inverter for the equipment after use. The generation of electricity consumption of electricity than facilities, the remaining energy will be against the current commercial network feeding power companies to buy (not yet implemented this system in China). Even in cloudy or rainy days, depending on how much sunlight can also generate electricity. However, the hair does not meet the power consumption of the installation, the absence of partially purchased from the utility. Unable to generate electricity at night, when facilities for electricity utilities to buy. Inspiron 8500 battery Inspiron 8600 battery

1. Solar cell module

The solar cell is a single device that can generate electricity, equivalent to about a 0.5 V battery voltage and battery components are the equivalent of a number of cells per series / shape parallel battery. The number of components of the composition of the solar cell is usually the system voltage (battery voltage) to decide, usually voltage component is 1.4-1.5 times the battery voltage. For example: battery voltage is 12V, the components of operating voltage is generally between 16.8-18V, while the number of cells 18v/0.5v number was 36. Therefore, the number of 36 or 40 commonly used components of high power 72.

After the combination may be encapsulated in a separate power supply for use as components of the solar cell with a certain amount of corrosion, wind, hail, rain capacity, widely used in various areas and systems. When applications require a higher voltage and current while the individual components can not meet the requirements, may consist of several components in solar cells up to get the required voltage and current.

2. Solar Inverter

Solar inverter is a power electronic circuit, solar panels can convert direct current into alternating current to operate appliances, lighting and power tools, the burden of communication throughout the solar system, a critical. Variable depending on mode of operation can be divided into stand-alone inverter and grid-connected inverter. Stand-alone inverter for stand-alone system of solar energy as a load independent. Grid-connected inverter for grid-run system, solar electricity will be injected in the network issued. Inverter waveform output can be divided by the square wave inverter and sine wave inverter.

Inverter has two functions: one is to complete the DC / AC power converter connected to the grid, the other is to identify the best operating point to optimize the efficiency of solar photovoltaic systems. For a given solar radiation, temperature and type of Sony VGP-BPS8 Sony VGP-BPS8A battery, solar photovoltaic systems have a voltage corresponding unique optimal and current, so that the largest photovoltaic system to generate energy.
