Zhou Zhengming and Gao Wenxin both lit cigarettes and carefully digested what Fu Xin had just said.

After a while, Zhou Zhengming raised his head, put his hand holding the cigarette under the chair, and asked Fu Xin seriously: "Comrade Fu Xin, can you tell me what are the benefits of this triple play integration?" ”

"That's a lot of benefits!" Fu Xinmei replied: "First of all, the integration of the three networks will make the information service from a single business to a comprehensive multimedia service such as text, voice, data, image, and video.

Second, the integration of the three networks is conducive to greatly reducing infrastructure investment, simplifying network management, and reducing maintenance costs.

Third, the integration of the three networks will transform the network from an independent professional network to a comprehensive network, improve network performance, and further improve the level of resource utilization.

Fourth, the future world is the network world, and the integration of the three networks is the integration of services, which not only inherits the original voice, data and video services, but also derives more abundant value-added service types through the integration of the network, such as graphic television, VOIP, video email, etc., which greatly expands the scope of business provision.

Fifth, the integration of the three networks has broken the long-term vicious competition between telecom operators and radio and television operators in the field of video transmission, and the major operators will grab food in a pot, and the tariffs for watching TV, surfing the Internet, and making calls may be packaged and lowered, which is also a gospel for the people! ”

"I noticed that you are integrating the three networks of telecommunications network, radio and television network, and Internet, and I am wondering, can we also add the power grid to save costs?" Gao Wenxin asked thoughtfully.

Fu Xin glanced at Gao Wenxin unexpectedly, and couldn't help but admire in his heart. The leaders who can achieve this high position are not simple people, and he suddenly has the prototype of the integration of the four networks in his mind! That's amazing!

Fu Xin thought about it and replied, "Yes." That requires a higher level of technology, though. I call that a smart grid. ”

"The integration of the three networks you said is not a moment and a half can be built, according to the existing situation of our country, there is no more than ten or twenty years, it will definitely not be done, so, you don't have to worry about technical problems, there is such a long time, technical problems can be slowly solved, you first talk about this smart grid." Zhou Zhengming had no intention of snatching the question raised by Gao Wenxin. So this is still Gao Wenxin is saying.

"Smart grid is the intelligence of the power grid, also known as "power grid 2.0", it is built on the basis of an integrated, high-speed two-way communication network, through advanced sensing and measurement technology, advanced equipment technology, advanced control methods and the application of advanced decision support system technology, to achieve the goal of reliable, safe, economical, efficient, environmentally friendly and safe use of the power grid, its main features include self-healing, motivating and including users, resisting attacks, providing power quality that meets the needs of users, Allows access to a wide range of different forms of power generation, activation of the electricity market, and optimal and efficient operation of assets.

The smart grid is composed of many parts, which can be divided into: smart substation, smart distribution grid, and smart energy meter. Intelligent interactive terminals, intelligent scheduling, intelligent home appliances, intelligent electricity buildings. Smart city power grids, smart power generation systems, new energy storage systems.

The development of smart grids is still in its infancy all over the world. There is no one precise definition in common, and I also read it in foreign magazines. Its technology can be broadly divided into four areas: advanced measurement system, advanced distribution operation, advanced transmission operation and advanced asset management.

The main function of the advanced measurement system is to authorize the user, so that the system can establish a connection with the load. enable users to support the operation of the power grid;

The core of advanced power distribution operation is online real-time decision-making and command, and the goal is disaster prevention and control, and the prevention of large-scale cascading faults is realized.

The main role of advanced transmission operation is to emphasize congestion management and reduce the risk of large-scale outages;

Advanced asset management is the installation of a large number of advanced sensors in the system that can provide the "health" status of system parameters and equipment (assets), and the integration of the collected real-time information with processes such as resource management, simulation and simulation to improve the operation and efficiency of the power grid.

Compared with the existing power grid, the smart grid reflects the significant characteristics of a high degree of integration of power flow, information flow and business flow, and its advancement and advantages are mainly manifested in:

First, the smart grid has a strong power grid infrastructure and technical support system, which can resist all kinds of external interference and attacks, and can adapt to large-scale clean energy and renewable energy access, and the strength of the power grid has been consolidated and improved.

Second, information technology, sensor technology, automatic control technology and power grid infrastructure are organically integrated, which can obtain panoramic information of the power grid and timely discover and foresee possible faults. When a fault occurs, the power grid can quickly isolate the fault and achieve self-recovery, thus avoiding the occurrence of large-scale power outages.

Third, the wide application of flexible AC or DC transmission, grid-plant coordination, intelligent scheduling, power energy storage, distribution automation and other technologies makes the power grid operation control more flexible and economical, and can adapt to the access of a large number of distributed power sources, microgrids and electric vehicle charging and discharging facilities.

Fourth, the comprehensive application of communication, information and modern management technology will greatly improve the efficiency of power equipment, reduce power loss, and make the operation of the power grid more economical and efficient.

Fifth, to achieve a high degree of integration, sharing and utilization of real-time and non-real-time information, to display a comprehensive, complete and fine power grid operation status map for operation management, and to provide corresponding auxiliary decision support, control implementation plans and response plans.

Sixth, establish a two-way interactive service model, users can understand the power supply capacity, power quality, electricity price status and power outage information in real time, and reasonably arrange the use of electrical appliances; Electric power companies can obtain detailed information on users' electricity consumption and provide them with more value-added services. ”

Speaking of this, Fu Xin was already smoking in his nostrils, drank most of the glass of water, and took a breath, Fu Xincai continued: "I think smart grid is an inevitable trend in the development of power grid technology.

With the development of the times, communications, computers, automation and other technologies will inevitably be widely and deeply applied in the power grid, and the organic integration of these technologies with traditional power technology will greatly enhance the intelligent level of the power grid.

The application of sensor technology and information technology in the power grid provides technical support for system state analysis and auxiliary decision-making, making it possible for the power grid to heal itself.

The mature development of dispatching technology, automation technology and flexible transmission technology provides a basic guarantee for the development and utilization of renewable energy and distributed power generation.

The improvement of the communication network and the popularization and application of user information collection technology have promoted the two-way interaction between the power grid and users. With the further development of various new technologies, applications and high integration with the physical grid, smart grids will inevitably come into being. (To be continued......)
