How much electricity was used this month? How much is the electricity fee? Don't wait for the power bureau to send the bills, and you will know the receipt message. This is a daily case of application of communication technology for power grid companies.
The rapid development of communications technology has become an important driving force for the transformation and development of power grid companies. Recently, China Southern Power Grid Corporation and China Mobile Corporation renewed the strategic cooperation framework agreement, not only will continue to write a new chapter in the complementary advantages of communications companies and power grid companies, but also bring unlimited expectations for the construction of smart grids with 4G technology.
Plug in communication "Wings", grid response will be more responsive
“The operation and management of modern complex large-scale power grids is inseparable from the support of communication networks. With the support of information technology, the grid response will be more sensitive.†At present, the company has built and operated a power telecommunications network with 138,000 kilometers of optical cables, and various types of cables. There are 46,000 communications equipment, covering 11,000 sites such as power grid dispatching agencies, power plants, substations and business outlets. Xu Jian, the communications department of the company's system operation department, stated that power communication, as an important basis for grid dispatching, network operation, and management modernization, has extremely high requirements for information transmission and reception.
With the expansion of the power grid scale and the refinement of user requirements, the requirements for the intelligentization of power dispatching systems have become higher and higher. In addition, since the “Twelfth Five-Year Plan†period, the company has proposed an integrated dispatching and operation system that requires the “overall fusion†of information communication operations monitoring, troubleshooting, and dispatching and commanding, which puts forward more stringent requirements for power communication technologies. The system operation department has been exploring how to establish a modern power grid with information, automation, and interactive features supported by communication information platforms.
"The "marriage with China Mobile" is to learn its advanced concepts in communications technology and management, and to identify our own positioning." Related personnel of the company's system operation department said that in the next step, the company plans to advance the development of unified communications. Try to establish standards, build a shared platform, and provide business support for production, information, market, safety supervision and other fields.
According to the agreement signed by the two parties, China Mobile will provide informatization solutions and mobile office applications and services such as internal office, dispatch, and management for China Southern Power Grid, and assist in building and improving the communication performance management of remote meter reading system terminals. Fast response and other services.
Integrate the advantages of both sides' network resources and welcome the 4G era
Smart grid is a hot topic in the development of power and energy industry in the world today. In the smart grid construction, communication technology is the foundation.
In the agreement signed by both parties, one of the highlights is that the company will integrate the advantages of both parties' network resources with China Mobile, and cooperate in TD-LTE communications technology, transmission network, voice service and marketing automation, and information technology level. TD-LTE communication technology is the 4G network that China Mobile is currently pushing. Its greatest advantage is its network speed. The arrival of the 4G era will have a profound impact on the smart grid construction.
At present, smart grids use wireless networks to realize data transmission, information processing, and customer perception applications. Smart grids are essentially a combination of power grids and information and communication. The core requirements for communication networks are safe and reliable operation control, and at the same time require a wide range of The user group coverage, efficient wireless network, to help achieve interactive interaction with the majority of users. China Southern Power Grid Corporation is committed to upgrading its existing power grids with advanced computer, communications and control technologies, comprehensively improving the safety, economy, energy conservation and environmental protection level of the power grid, and the level of service to its customers, striving to build an intelligent, efficient and reliable system. a green modern power grid.
At the signing ceremony, Wang Liangyou, deputy general manager of China Southern Power Grid Corporation, stated that the next step would be to further study the application of 4G and IoT technologies in the line of business such as line monitoring, primary equipment condition monitoring, meter collection and copying, emergency security, warehousing logistics, and inspection and inspection. At present, it is important to study technical difficulties such as high-voltage induction power transmission line transmission and standardization of meter communication interfaces.
Sha Yuejia, vice president of China Mobile, said that the smart grid is inseparable from the informational support. China Mobile will provide comprehensive information services for the China Southern Power Grid through the convergence of fixed networks, mobile networks, and the Internet, covering applications ranging from basic communications circuits to power industry applications and efficient collaborative office integration and communications applications, helping China Southern Power Grid create efficient and reliable services. Smart grid.
