According to incomplete statistics, since April, with the commissioning of the Huaibei 110-kilovolt Tan Substation and the Ningbo 110-kilovolt Yunlin Substation, the number of smart substations built in China has reached 10. From the Beichuan 110 kV smart substation to the 220 kV Xiqiao smart substation, the 500 kV Lanxi substation to the world's highest voltage level substation, the 750 kV Yanan substation, was put into operation. The pilot project of the smart substation in China continues to make progress. This will open the prelude to the large-scale construction of smart substations in China, and it will also have important significance for building a strong smart grid in China.
Smart substation pilots continue to make new progress
Beichuan 110 kV smart substation is one of the second batch of smart grid pilot projects of the State Grid, and it is also the first intelligent substation to be put into operation in the northeast corner of Beichuan New County. On April 21, the reporter went to the Beichuan 110 kV smart substation to conduct an on-site interview. Intelligent elements such as high-definition cameras, solar panels, and environmental sensors have come into view. On the display screen of the control room on the second floor, all the data is collected here. The control room controls the entire 100,000-kilowatt power supply load in the new county of Beichuan, just like a “smart heartâ€. Moreover, with this as the starting point, 5000 remote fee control tables and 7400 single-phase smart meters will form a smart circle, which will include the entire Beichuan county into the intelligent management category.
"Northern Sichuan Substation takes the digital information of the entire station, the network of communication platforms, and the standardization of information sharing as its basic requirements. It automatically completes basic functions such as information collection, measurement, control, protection, measurement, and detection, and realizes unattended operation, automatic control, and status detection. Advanced features such as smart regulation, cooperative interaction, etc.†Yang Zitao, leader of maintenance operation team of Beichuan Power Supply Company of Mianyang Electric Power Bureau, introduced, “Compared with conventional substations, it has the characteristics of resource conservation, environmental protection, smart equipment, and advanced technology, making Beichuan Grid Resilience, transmission and distribution capabilities, and intelligence have increased significantly."
Beichuan Smart Substation is of great significance to the development of smart substations in China. Subsequently, China has successively constructed the first 220 kV Xiqiao smart substation in China, the first 500 kV Lanxi substation, and the world’s highest voltage class smart substation— the 750 kV Yan’an substation... China’s smart substation has become a leading global substation technology The backbone of development. In addition, as of now, the State Grid has formulated 15 smart substation standards, forming the world's first series of technical standards for smart substations. Applied for 126 patents, and the overall technical level leads the world.
Realize the breakthrough from digital substations to smart substations
So what are the characteristics of smart substations? Shu Yinhao, deputy general manager of the State Grid Corporation of China, said: “Smart substations can significantly increase the level of equipment intelligence and equipment operation reliability, automate unattended operation and equipment operation, improve resource use and production management efficiency, and make operations more economical and energy-efficient. "Environmental protection." Take the Qingdao No. 1 220-kilovolt transformer station as an example. Comparing with the ordinary substations, the cost savings of 22.4 million yuan can be achieved in terms of 15 years of equipment life.
Intelligent substations are the upgrade and development of digital substations. Based on the digital substation, combined with the needs of the smart grid, the substation automation technology is enriched to realize the intelligent function of the substation. The design and construction of intelligent substations must be carried out in the context of smart grids. They must meet the requirements of China's smart grid construction and development, and reflect the characteristics of China's smart grid informatization, digitization, automation, and interaction.
Facts have proved that in the process of building a smart substation, China has continuously made breakthroughs in its "intelligence". For example, the Xiqiao Substation's related equipment is the first implementation of a large-scale, multi-parameter on-line monitoring system for on-line integration and remote application in the country. The first use of the Internet of Things technology to establish a sensor monitoring and control network; 750 kV intelligent substations in Yan'an intelligent station ultra-high voltage electronic transformers, circuit breakers and transformers and other smart devices for the world's first set; set up a unified state monitoring platform, to achieve a super Large-scale, multi-parameter on-line monitoring back-end system integration and remote application of high-voltage smart substations.
Smart substation construction will usher in explosive growth
The first 220 kV new smart substation in Southern Hebei Power Grid started construction. Rizhao Power Company formally started the construction of a 110 kV smart substation. Gansu Provincial Electric Power Company's “Twelfth Five-Year†substation intelligent transformation planning work started, and Zhongwei Zhongwei’s first smart substation settled in Zhongning. , Hubei test water smart substation ... These are just a microcosm of the construction of smart substations throughout China.
At present, the State Grid has made smart substations one of its promotion efforts. According to the relevant plans of the State Grid, smart substations will become the mainstream of newly-built substations and usher in explosive growth: 46 new smart substations will be built in the first phase, 28 will be intelligently transformed in the substations, and 8,000 new smart substations will be built in the second phase. 50 substations were intelligently reconstructed, and 48 UHV AC substations were reconstructed. In the third phase, 7,700 smart substations were newly built, 44 substations were intelligently transformed, and 60 UHV AC substations were reconstructed.
Statistics show that in the next 10 years, the scale of intelligent investment in the substation will reach 74.8 billion yuan, accounting for 19.5% of the total intellectual investment. Substation equipment mainly includes transformers, circuit breakers, transformers, busbars and other primary equipment and secondary equipment such as substation automation systems, auxiliary systems, and intelligent components. In response, Jiang Kezheng, director of the Energy System Analysis and Market Analysis Research Center of the Energy Research Institute of the National Development and Reform Commission, said: "The grid companies are open to suppliers of smart grid related equipment and can purchase according to local conditions, not just Chinese companies. â€
