[Abstract]:With the development of national economy, electricity demand continues to rise, the development of power network dispatching data communication reliability protection, real-time control and accuracy of information transmission, strengthen the construction of electric power dispatching data network has become the priority among priorities. Electric power dispatching data network is the power production base to maintain safe and stable operation of power grid, plays the core the role of residents in production and social management. From the study of domestic and foreign literatures, combined with the Nanchang company control center daily work, information network of electric power data network were studied. (1) the appearance point of researchers in the United States will power grid development direction is defined as "smart grid", "smart grid" theory support and technical support for the integration of power users and the market, in theory, can be built into the system is intelligent, which has self-healing function and automatic response function, intelligent AC For information, to meet the primary human society to respond to emergencies. Europe also made a similar "assumption and conception of smart grid", but in Europe more comprehensive information integration and all-round monitoring to promote market power trading, power supply, safety coefficient of the maximum possible increase of power grid operation, efficiency and operational efficiency threshold and the minimum impact on the environment, to achieve green and meet the growing demand of industrial life. (2) the research direction in China, national Power Grid Corp has insisted on a digital information, improve the power grid automation level and improve the level of enterprise management. In the transmission, substation and distribution and other aspects of the realization of dynamic statistical data reporting and intelligence summary, grid information in broadband network construction of the main facilities has begun to take shape, the construction of UHV direct transmission The line has adopted the information network monitoring technology. At present, the domestic use of the national power grid dispatching automation system has been in the international advanced level, in the 6 known IEC61850 and IEC61970 standard interoperability test, experimental results show that the electric power dispatching automation integration system in improving the scheduling data, adjust the integrated data platform in the leading level of State Grid. Encourage provincial grid companies to establish digital electric power company, the use of broadband network for distribution, scheduling and marketing management; the use of video surveillance of substation remote control. (3) the application system of the power grid enterprises lack of dragons and fishes jumbled together, can basically meet the business and one to two department daily work between systems not compatible with different data formats, making the company system is unlikely to achieve data internal coordination between information resources, caused by dispersion, shape As an "information island" longitudinal multi-level, multi lateral system, information clutter, incomplete and repetition makes the information can not be shared, not to mention the effective information, efficient processing of electric power dispatching data network is a communication network based on the implementation, routing, switching and improve power dispatching business access. The information, information collection, integration, distribution to their needs in the integrated transmission platform, greatly improve the unified data transmission and exchange between all levels of the dispatch center and the center and the station platform, will expand into a business carrier. In the power grid development today, power dispatching data network has set the scheduling information grid automatic control, and other functions. At the same time as the management operation, basic safety and stability control and automation, to ensure the normal operation of power market, perfect the modern power system, has become indispensable in the system Factors of production management, also benefited from the normal thinking, and strengthen the data network construction is also very necessary. Compared with other domestic industries, the power industry has different properties, grid enterprises often face the operational level, cross a wide range of production conditions and bad characteristics of higher risk, in order to improve the power grid operation efficiency, power grid enterprises often want safe operation of power grid dispatching reasonably, reduce the loss, pressure loss, so rely on communication developed high quality communication effect brings convenience, Nanchang power supply company will use this kind of new technology, new technology to protect the power grid dispatching remote control, making the network more secure, but also highlights the construction of power communication network the economic cost of high value. With the development of power grid construction in Nanchang area, Nanchang power supply company in the operation of 13 220kV power transmission engineering, substation, and at the same time, Nanchang area Power dispatching data network is experiencing a severe test, urgent need to increase the network bandwidth capacity expansion, and improve the network transmission speed, plans to complete the basic optical fiber communication of the city in 3 years, transmission network of two counties, Nanchang county to achieve full coverage. The dispatching system is a digital high level in the platform. Domestic technical level has established a perfect management system of energy and electric energy metering system, but subject to the network transmission in the platform restrictions. In the rapid development of science and technology, the traditional network application system has been unable to meet the demand of electric power development, and even can not adapt to the trend of network technology, the trend of grid data trend has an information transmission system for the organization will change. In order to meet the needs of the business system, meet the basic requirements of real-time, the focus is to be Provide network platform with field data, namely power dispatching data network. The national grid has been committed to the development of UHV power grid and the safe and stable operation of power grid dispatching, meet the safety requirements, reliable transmission, and provide technical support for the stability of the reserve dispatching technical support system, the dispatching data network in the next step development gives direction. The research content of this paper is dispatching data of Nanchang area, analysis of power grid scheduling, scheduling is analyzed in practice what is required, this article mainly launches the research from the following parts: first introduced the electric power communication network, and the shortcomings of the current situation of the development of the electric power dispatching data network, from the business needs. Technology system, routing strategy, network functions, network performance, network security, network management and other aspects of in-depth research and analysis, put forward the construction of an advanced network technology and The high efficient, stable, secure network construction principle and network optimization scheme for the reliable network topology.
