Power grid has a very important position and value in the modern information age. However, it is necessary to continuously improve the economy and reliability of power grid operation, give full play to the advantages of power grid, and fully adapt to the current information development era.

1. Electric power needs highly safe and stable control system, automatic monitoring system and highly modern communication system.

(1) Overview of power communication. As a member of the world power communication family, China power communication has also experienced unprecedented rapid development and great changes. On the whole, we are working hard in the direction of reflecting the characteristics of China and being isolated from the world trend. Entering the new century, we are full of hope and confidence, and look forward to the bright future of China electric power communication.

(2) The development status of power communication technology. The development of China electric power communication system is very rapid. In just a few decades, it has experienced the development process from open wire and coaxial cable to optical fiber transmission, from fixed-point communication to mobile communication. Power communication is an important part of China's power grid and a highly professional communication network. Now, the network communication technology is also developing by leaps and bounds, and the power communication network is also growing, which requires that power communication needs to be improved and perfected in many aspects.

2. The main structure and service types of power communication system.

(1) The power communication system consists of three parts, namely, communication institutions, communication equipment and communication services. The three are indispensable, and the backwardness of any link will lead to the lag of power communication development. Therefore, the research on the development direction of electric power communication in the new era should focus on the reform of system, the improvement of communication equipment technology and the development and expansion of business market.

(2) Types of communication services in power system. (1) production control, such as telephone adjustment, remote protection, sports, etc. (2) Administrative management, such as administrative telephone, fax, 0A data, etc. (3) Market operation, such as e-commerce between power enterprises such as B2G and power customers. Because the power system has its special requirements for communication services, some key services are difficult to meet in the general public communication network.

Three. Basic tasks of electric power communication in the new era

(a) continue to improve and perfect the power dedicated communication, to provide a more reliable guarantee for the safe, stable and economic operation of the power system.

(2) We should make full use of power facilities and power communication facilities, form and expand new value growth points, and create a good foundation for maintaining the development potential of power communication and improving the competitiveness of power enterprises. (1) System reform of electric power enterprises. (2) develop special exchanges. (3) explore external markets. (4) Supporting reform.

4. Application of power communication in power system

(a) the construction of electric power communication synchronization network.

(2) Power communication system in power generation field.

(3) Power communication system in the field of power consumption.

(4) Power communication system in the field of power consumption.

(5) Power communication system in smart grid.

Verb (abbreviation of verb) shows the problems in power communication.

(A) The lack of strong unified planning and management. First, the power system master, as a subsidiary system of the power system, determines that it cannot formulate a reasonable unified planning according to the law of the development of power system communication itself. Second, the investment in power system communication comes from power plant and substation construction projects, which also affects the implementation of unified planning to some extent. Third, during the late Eighth Five-Year Plan and the Ninth Five-Year Plan, the diversification of investors and the imbalance in the development of power construction projects further reduced the guidance of unified planning.

(2) Pay more attention to construction than operation. Because it is a national investment, the power communication project does not separately distribute the tiger income, so it is necessary to compete for the project during the project establishment period, "eat" the investment during the construction period, and try not to invest during the operation period. This will affect the safe, stable and reliable operation of power system communication and restrict the full play of its communication ability.

(3) Production management is basically orderly and management is seriously lacking. Due to the lack of operation demand, the power system communication lacks the concepts of telecom management and operation management and the corresponding talents in the network, and even lacks the market and talent concept of developing the communication market. Poor management is the main reason for the serious waste of communication investment in power system.

(D) the lack of professional and technical personnel, technical research atmosphere is not strong, academic leaders and technical experts are few.

(5) Lack of consciousness and ability of self-improvement and development. Long-term passive dependence on supporting project investment in substation construction of power plants, long-term free communication service of power enterprises and long-term lack of funds for technical transformation of power communication have seriously restricted the self-improvement and development ability of power system communication.

(6) Communication technology revolution. The communication network structure is weak. At present, the national power communication system, the communication network structure is basically a tree structure or a star structure or a combination of the two, and the style interconnection is relatively poor, so it is difficult to form a circuitous circuit, let alone self-healing.

(7) The network management system is not perfect. At present, the network management system of power system communication network has not really been realized, and it can only be PCM, ADM and channel machine, so it is difficult to form an overall communication network management.

(eight) trunk equipment aging, backward standards. Due to the aging and unstable operation of communication equipment components, it is difficult to guarantee the quality of equipment operation. At the same time, due to the aging of standards, communication circuits lack flexible application, which makes it difficult to adapt to the development of new communication technologies.

Measures taken by intransitive verbs

(1) Power information infrastructure is a comprehensive high-speed information transmission platform including transmission, exchange and various supporting networks, in which transmission is the foundation, exchange is the core, and supporting networks are the guarantee, which constitutes the main body of communication information infrastructure. Therefore, we should take corresponding measures from the following aspects. (1) Conduct market research. In the process of gradually opening up the telecommunications market, power communication should be based on the power system and provide society for the society. (2) Guarantee technical support. The arrival of IP era also puts forward new requirements for access network, including: fast real-time, broadband multimedia, integration, two-way asymmetry, mobility and scalability. Its biggest feature is broadband, that is, using fiber-to-the-home or XDSL technology, using existing copper cable resources or HFC technology, and actively developing broadband access technology for users.

(2) improve the quality of personnel. Science and technology are the primary productive forces and the driving force for enterprises to keep moving forward. Now the key to enterprise competition is talent competition. In order to make the enterprise in an invincible position, it is necessary to increase the training of professional and management talents, recruit talents through various channels, build a power communication team that understands technology, is good at management and can operate, and improve the service quality of the whole power communication to meet the needs of modern communication development and telecom market development.

Concluding remarks

To do a good job in the development of electric power communication industry, we must rely on solid power grid structure, advanced communication network and perfect financial and legal system as support. At present, power communication technology is in a period of steady development in China, and its development prospects and vitality are very strong. Therefore, the investment of power communication technology and capital is an important aspect.
