The so-called smart grid is the future direction of the grid incisive summary. That is, in generation, transmission, distribution, electricity and other aspects of application of a large number of new technologies, and ultimately the optimal allocation of electricity use and energy conservation. Currently, in addition to China,glue stick the United States, Japan and other countries have also introduced similar plans. United States April 16, 2010 $ 4,000,000,000 announced investment plans smart grid technologies.
The definition of the U.S. smart grid has seven characteristics: self-healing, interactive, safe and provide the needs of the 21st century power quality, adapt to all types of power and energy storage methods can be market-oriented transactions, optimize network assets to improve operational efficiency.
America is promoting the smart grid, directly aimed at stimulating the U.S. economy, out of contributing to the current financial crisis. Many U.S. power companies, power grid stable, mature and have sufficient supply capacity of power transmission and distribution, equipment obsolescence, strong secondary equipment weak grid have been part of the distributed power. Therefore, the smart grid planning focus on regional coordination,glue gun the electricity market and power networks, upgrading infrastructure update, distributed power access, the user part of two-way interaction, while maximizing the use of information technology, an alternative system of artificial intelligence.
China's smart grid is defined as a strong intelligence network, covering power generation, scheduling, transmission, distribution and all aspects of the user, is a closed-loop system. State Grid Corporation is building a strong, smart grid, that is building for special high voltage power grid as the backbone frame, strong and coordinated development of all levels of power grid and power network of information, digitization, automation, interactive, in the power supply security, on the basis of reliable and high quality, and further to achieve clean, efficient and interactive goals.
First Smart Grid in China should be a strong power grid, enabling a wide range of energy resources, optimal allocation, security safe and reliable supply of electricity. Based on the grid in a strong network of information technology, digitization, automation, interactive is a strong and smart grid "smart" means.
Intelligent power grid construction in China has actually already in progress, but not in "smart grid" of the fashionable name of it, China's digital smart grid power grid construction can be regarded as the prototype. Digital China Power Grid covers the construction of power generation, scheduling, transmission, distribution and all aspects of the user, components include: information technology platform, automation system, stability control systems, flexible AC transmission, substation automation systems, microcomputer relay protection , distribution network automation system, power management collection system.
Strong and smart grid intelligence aspects of the investment will reach 660-680 billion per year. In China, the process of building the smart grid, advanced automation system, flexible transmission, digital switching, digital transformers, distribution automation, power management collection system will be a huge growth market space.
Digital Substation enormous impact on the electrical equipment industry, will lead to secondary equipment industry, transformer industry, and even the shuffle switch industry and as a link to IEC61850 will promote the primary equipment and secondary equipment, and infiltration of mutual cooperation of enterprises, the new M & A opportunities will be generated.
State Grid Corporation of a strong intelligence network in three steps: ① 2009 ~ 2010 plan year pilot phase, a strong focus on smart grid development planning, development of technical and management standards, in the critical technology research and development, equipment development and all aspects of the pilot. Listed companies have benefited significantly from TBEA, high level of electrical, Tianwei change, State Power NARI, Siyuan Electric, Hidenobu shares Clou Electronics. ② 2011 ~ 2015 full-year construction phase, accelerate the construction of north, east and central "three Chinese" special high-voltage synchronous network, formed to run the smart grid control and interactive service system, key technology and equipment to achieve major breakthroughs and widely used. Listed companies have benefited significantly from TBEA, high level of electrical, Tianwei change, State Power NARI, Siyuan Electric, Hidenobu shares Clou Electronics, XJ Electric, the National Power South, Long Park Group, Dongfang Electronics. ③ 2016 ~ 2020 years to lead the upgrade stage, full completion of the unified strong and smart grid technology and equipment fully reach the international advanced level.
