Fu Xin stopped, and the two big guys, Zhou Zhengming and Gao Wenxin, began to think deeply. After a while, Zhou Zhengming asked: "What kind of construction conditions are needed for this smart grid?" "Construction conditions" Fu Xin said thoughtfully: "I didn't think about this construction conditions carefully. After all, we The country's current power grid is not very perfect, and power outages happen frequently" Seeing that Zhou Zhengming and Gao Wenxin's expressions did not change, Fu Xin continued: "So, I only consider one option: UHV The construction conditions of the smart grid model based on the coordinated development of the power grid as the backbone grid and the coordinated development of power grids of all voltage levels are what I call the construction conditions of the strong smart grid. " "Tell me about it," Zhou Zhengming said. Fu Xin nodded and said thoughtfully: "First, in terms of power grid construction, we must continuously strengthen and improve the grid structure, and make the UHV AC test demonstration project and UHV DC demonstration project successfully put into operation and operate stably; It is necessary to fully master the core technology of UHV power transmission and transformation to lay a solid foundation for the development of the power grid. Second, in terms of large power grid operation control, it is necessary to have the institutional advantages of "unified dispatch" and rich operational technical experience, and have a minimum level of dispatching technology and equipment. To lead the world, independently developed dispatching automation systems and relay protection devices must be widely used. Third, in terms of communication information platform construction, a power communication backbone network of "three vertical, three horizontal and one ring networks" should be built to form optical fiber communication. The communication network pattern is mainly based on the coexistence of multiple communication methods such as microwave and carrier; the SG186 project must achieve phased results, and business application systems such as ERP, marketing, and production must complete pilot construction and begin large-scale promotion and application.¡± Seeing that Zhou Zhengming and Gao Wenxin were very confused, Fu Xin immediately realized that he had let something slip, so he explained: Uh I'm a little embarrassed to say it, "I named the 'Three Vertical, Three Horizontal and One Ring Network' and the SG186 project myself. "Three vertical, three horizontal and one ring network" refers to the Mengxi, Simon, Beizhang and Beishan energy bases transmitting power to North China, East China and Central China through three longitudinal UHV AC channels, with northern coal power and southwest hydropower passing through the three. A horizontal UHV AC channel transmits power to North China, Central China and the Yangtze River Delta UHV ring network. Among them, the three vertical lines are: Mengxi to Jinling, Beizhang to Hongcheng, and the three horizontal lines are: Simon-Fang. Three horizontal transmission channels are Wei, Zhongjin-Zhouxu, and Anya-Nanwan. In addition, the Nanhuai-Jinling-Zhoutai-Zhousu-Haihai-Northern Zhejiang-Wannan-Nanhuai Yangtze River Delta UHV double-ring network is also constructed. The project refers to using '1' platform, '8' major applications, and '6' systems to weave a huge information network of "vertical connection and horizontal integration" of our national grid, so I named it SG186 project. The '1' in the SG186 project refers to an integrated enterprise-level information integration platform. After the construction of this platform is completed, it will have a unified data exchange function to achieve 'one entry, multiple uses' to ensure the authenticity of the data. , consistency and integrity are guaranteed. At the same time, the platform is also responsible for smoothing information channels, promoting business integration, integrating existing application systems, avoiding duplication of construction, reducing development costs, eliminating information "islands", and playing a role in production, operation, and A series of functions such as realizing data sharing in management and other aspects, and establishing a global data dictionary for the enterprise. The '8' in 'SG186 Project' refers to the construction of financial management, marketing management, production safety management, collaborative office management, human resources management, and materials. Eight major business applications: management, project management, and comprehensive management. Through integration, improvement, reconstruction, and new construction, data sharing between applications will greatly improve the quality and efficiency of work. It refers to the need to 'establish and improve six information security systems'. These six systems are: information security protection system, standard specification system, management and control system, evaluation and assessment system, technical research system and talent team system. These systems can provide necessary resources, technology, management and talent protection. " Zhou Zhengming and Gao Wenxin, while digesting Fu Xin's advanced ideas, motioned to Fu Xin to continue. Fu Xin continued: "Let me continue to talk about the previous construction conditions of the smart grid! Fourth, in terms of testing and testing methods, it is necessary to establish large-scale wind power grid, solar power generation and electricity technology research and testing centers based on the needs of smart grid technology development. Fifth, in terms of smart grid development practice, pilot work in all aspects must be carried out in an all-round way, and projects such as smart grid dispatching technical support systems, smart substations, power consumption information collection systems, power distribution automation, and power fiber to the home must be implemented. Sixth, in terms of large-scale renewable energy grid connection and energy storage, it is necessary to carry out in-depth research on key technologies such as centralized grid connection and electrochemical energy storage, and establish simulation analysis of wind power integration into the power grid.Platform to formulate relevant technical standards for wind farms to be connected to the power system. Seventh, in terms of the power grid development mechanism, the business scope of my country's power grid department must cover all aspects from power transmission, transformation, distribution to power consumption, and there must be obvious advantages in unified planning, unified standards, and rapid advancement. Oh, by the way, Minister Zhou and Minister Gao, regarding this construction condition, I made a pyramid diagram, which can clearly reflect the construction condition framework of the strong smart grid. " After saying that, Fu Xin took a piece of paper handed over by Secretary He and started drawing on it. After a while, Fu Xin drew a six-story pyramid-shaped framework of construction conditions, and arranged them from high to low on the frame. The six articles and twenty-four words "one goal, two main lines, three stages, four systems, five connotations, and six links" were written. On the side of the framework, Fu Xin also attached some comments on it. A simple explanation of the six articles and twenty-four words is as follows: One goal - to build a unified and strong smart grid with UHV as the backbone grid and coordinated development of power grids at all levels; Two main lines - technically embodying informatization, automation, Interactive, management reflects collectivization, intensification, leanness, and standardization; three stages - planning pilot stage, comprehensive construction stage, and leadership improvement stage; four systems - power grid basic system, technical support system, and intelligent application system , standard specification system; five connotations - strong and reliable, cost-effective, clean and environmentally friendly, transparent and open, friendly interaction; six links - power generation, transmission, transformation, distribution, electricity consumption, and dispatching. "For the three stages. and five connotations, let me give a simple explanation! After Fu Xin finished drawing the picture, he said: "In the planning pilot stage, we will focus on the preparation of smart grid development plans, formulate technical and management standards, carry out key technology research and development and equipment development, and carry out pilot work in all aspects; in the comprehensive construction stage, we will accelerate In the construction of UHV power grids and urban and rural power grids, a smart grid operation control and interactive service system has been initially formed, and major breakthroughs and widespread applications have been achieved in key technologies and equipment; Leading the upgrade stage, we will comprehensively build a unified and strong smart grid to improve the resource allocation capabilities and security of the power grid. level, operating efficiency, and the interaction between the power grid, power sources, and users have been significantly improved. Strong and reliable, that is, having a strong grid structure, strong power transmission capacity and safe and reliable power supply; Economic and efficient, that is, improving power grid operation and transmission efficiency, reducing operating costs, and promoting the efficient use of energy resources and power assets; Clean and environmentally friendly , that is, promoting the development and utilization of renewable energy, reducing energy consumption and pollutant emissions, and increasing the proportion of clean electricity in terminal energy consumption; Transparency and openness, that is, the transparent sharing of information on the power grid, power supply and users, and the non-discriminatory opening of the power grid; Friendly interaction , that is, to realize the flexible adjustment of the power grid operation mode, be friendly and compatible with the access and withdrawal of various types of power sources and users, and promote the active participation of power generation enterprises and users in the regulation of power grid operation. ¡± ¡°Broadly speaking, smart grid includes intelligent dispatching systems that can prioritize the use of clean energy, intelligent metering systems that can dynamically price, and intelligent technology systems that optimize load balance by adjusting the power of power generation and electrical equipment. When a smart grid is built, electric energy can not only flow from centralized power plants to transmission grids, distribution grids and users, but also various forms of new and clean energy are spread throughout the grid: solar energy, wind energy, fuel cells, electric vehicles, etc.; In addition , the high-speed, two-way communication system can realize information interaction between the control center and the power grid equipment, and the advanced analysis tools and decision-making system ensure the safe, stable and optimized operation of the smart grid. The goal of smart grid is to make the grid operation reliable, safe, economical, efficient, environmentally friendly and safe to use. If the grid can achieve these goals, it can be called a smart grid. ??Smart grids must be more reliable - smart grids can provide reliable power supply no matter when and where users are. It provides adequate warning of possible problems in the power grid and can tolerate most grid disturbances without power outage. It can take effective corrective measures before users are affected by power outages to protect grid users from power supply interruptions. Smart grids must be more secure¡ªsmart grids that can withstand physical and cyber attacks without widespread outages or costly restoration costs.
