In 2012 China’s future prospects of smart grid

In today’s economic development trend, the traditional power grid has been nearly can not meet the demand for electric power industry, become the development direction of smart grid. But for now, power grid has become industrialized, informatization and social development of the basic and important component part. It can be said that China’s smart grid with a good development prospects.

With the development of the market reform, the smart grid has become a modern power system technology development the route one must take. China ‘s smart grid is to strong grid as the foundation, take information communication platform, intelligent control means, including power generation systems, transmission, substation, power distribution, electricity and scheduling of each link, covering all the voltage level, to achieve ” power flow, information flow, business flow and highly integration “, is strong and reliable, efficient, clean, transparent and open, friendly interactive modern grid. Smart grid by establishing a digitized information network system of energy resources from the development to the terminal user all kinds of electrical equipment and other energy-consuming facilities combined, through the intelligent control for the precise, correspondence, mutual and complementary, and comprehensively improve the efficiency of energy utilization and energy supply security level, the pollution and greenhouse gas emissions to the environment can undergo the procedure, the user cost and investment benefit to reach a rational state.

Smart grid concept and characteristics

The smart grid is that information technology, communication technology, computer technology and the original transmission, distribution infrastructure highly integrated and the formation of a new type of power grid, it can improve energy efficiency, reducing the impact on the environment, improve power supply security and reliability, reduce the transmission power loss and many other advantages.

The intelligence is mainly reflected in: observable — measurement, sensing technology; control — observations on state control; embedded self processing technology; real-time analysis — from data to information enhancement; adaptive; self-healing.

With the problem of energy tension, power system is facing great challenges and opportunities. On one hand, the grid to deal with increasingly serious resource and environmental pressure, not only needs to realize large range of optimal allocation of resources, but also adapt to the reform of electric power system; on the other hand, informationization, digitalization, intelligent technology to solve a series of problems to provide a solid technical support.

In 2020, China will build a strong unified smart grid, the establishment of high-speed, two-way, real-time, integrated communication system is the realization of the smart grid infrastructure, no such communication system, any smart grid features can not be achieved, power communication system is electric power automation is an important part of. Communication system of many kinds, such as the RS485 bus technology, fiber optic transceivers fiber covering technology, series / parallel port and serial port communication technology, Ethernet network server ( Ethernet ) network communication technology. The optical fiber technology for smart grid construction offers a full range of communication services. Information intelligence make a spurt of progress, Ethernet Broadband access way is therefore referred to a more and more important position. At the same time, optical fiber communication with its large information capacity, confidentiality good, light weight, small volume, no relay, long distance of transmission has been widely applied, fiber optic transceivers is the use of optical fiber the high-speed transmission medium well solves the problems in the transmission of ethernet. Especially in some of the requirements for a high degree of information, the data flow of large government agencies and enterprises, network construction needs to directly connected to the optical fiber as the transmission medium of the backbone network, while the internal local area network transmission medium for copper wire, ensure that the data packets between different network smooth transmission medium conversion equipment necessary.

Smart grid is the new trend of the development of modern city

Today’s era of global informatization, network technology rapid progress of the times, the building of intelligent city world city development is a common target. In the smart city many construction projects, the smart grid is one of the key projects.

As the world economy and the rapid development of science and technology, society, economy, clean, efficient energy security energy demand increasing.

The smart grid can realize the clean energy of large-scale flexible access, improving the security and stability of power system and other advantages, the development of intelligent electric energy in twenty-first Century to become the world’s countries agreed direction. Some experts have described the smart grid, ” simply put, is to make the power grid more ‘ smart ‘, the public electricity more ‘ wisdom ‘. It can be the shortest time, isolating the fault recovery of power supply, when the distributed clean electricity surplus, use electric door also can put electric sold … … ” This is to the smart grid in the future life of the application of the image description.

State Grid Energy Research Institute of smart grid research institute director Zhang Yibin to think, the smart grid as a modern city is an important part of the development, smart grid, can be from a number of aspects to promote the city’s intelligent. ” First, the smart grid itself is the information channel and multiple integration of information carrier, therefore the development of smart grid can improve the city network communication capacity; second, to promote the rapid development of related industries, the smart grid and state just forward of the ” strategic emerging industry development planning ” in the six industries are related; third in the implementation, the transformation of economic development mode in the background, a smart grid is visible work ‘ gripper ‘; fourth, the smart grid can promote renewable energy, new energy development, promote energy-saving emission reduction, promote energy efficiency improvement, and these are closely related to the development of the green city. “
