Shandong Electric Power Introduces Measures to Promote Strong Smart Grid Construction

On April 15th, the reporter learned from Shandong Electric Power Group Corporation that the company recently issued the “<Comments on Accelerating the Implementation of Shandong Strong Smart Grid Construction Strategic Cooperation Agreement”, focusing on the six key contents of the “Strategic Agreement”. The company dismantled its work tasks, formulated 30 key measures, fully promoted the construction of a strong smart grid with full speed, full speed, and strived to establish a strong smart grid in the State Grid Corporation of China in advance one year ahead of schedule.

On March 8th, State Grid Corporation of China and the People's Government of Shandong Province signed the "Strategic Cooperation Agreement on Accelerating the Construction of a Strong Smart Grid in Shandong Province." Shandong Power Group Corporation attached great importance to it and acted swiftly. It carefully researched and formulated the implementation measures, and specifically issued the "strategic agreement" to implement the opinions and comprehensively promote the construction of a strong smart grid. During the “Twelfth Five-Year Plan” period, Shandong Electric Power Group planned to invest 110 billion yuan, and initially established the national grid company system with UHV as an important support, coordinated development of power grids at all levels, and strong intelligence with the characteristics of information, automation, and interaction. Grid.

To this end, Shandong Power Group will build a strong security system, strengthen the organization of leadership and personnel team building, strengthen scientific and technological support, and actively strive for the wide support of all sectors of the community to advance the work, and fully guarantee the construction of a strong smart grid. The UHV and smart grid construction will be fully integrated into the national “Twelfth Five-Year Plan” outline, and the “Twelfth Five-Year” development plan of Shandong Power Grid will be fully integrated into the Shandong Provincial Energy Development Plan, a new round of overall land use planning and urban and rural development in the province. Planning as an opportunity to complete the planning and interconnection of the 17 provincial power grids in the province, and strive for the extensive support of governments at all levels and all sectors of society to jointly accelerate the construction of UHV grids and smart grids.

During the “Twelfth Five-Year Plan” period, Shandong Electric Power Group will rely on the construction of the main grid of “three vertical and three horizontal” UHV of the country to build Jinan, Weifang UHV substations and Ximeng-Beijing East-Jinan-Xuzhou-Nanjing and northern Shaanxi- From Jinbei to Shijiazhuang-Jinan-Weifang UHV power transmission channel, the construction of ±800 kV Hulun Buir-Shandong, ±660 kV Bin-Shandong DC project will be completed. By 2015, it will receive more than 16 million kilowatts of external power.

At the end of the “Twelfth Five-Year Plan” period, Shandong Power Grid will have two UHV AC substations, three DC converter stations, and 46 500-kV substations. Line lengths of 110 kV and above will exceed 55,000 km, and the capacity will exceed 3 Billion KVA. Shandong Power Grid has two UHV AC landing points as its important support. Three DC drop points have penetrated into the load center. The 500 kV ring network covering all cities in the province is the main grid, and the 220 kV grid is used as the master of the regional power grid. The network rack and distribution network have been fully enhanced, and the power supply capacity and power supply safety and reliability have been fully enhanced.

During the “Twelfth Five-Year Plan” period, Shandong Electric Power Group will comprehensively speed up the construction and transformation of smart substations, build 408 new smart substations and 508 substations in an intelligent way. The proportion of smart substations in the whole network exceeds one-third; it will strive to achieve in 3 years. The distribution automation coverage rate in the core areas of cities in 17 cities across the province has reached 100%; the customer power consumption information collection system has been built to achieve full coverage and full collection, enabling friendly interaction between the power grid and customers; and establishing a complete power communication network and integrated information The platform has formed an integrated smart grid dispatching system; an electric vehicle smart charging and replacement service network has been initially established, and the total number of charging and replacing facilities in the province has exceeded 3,704, creating conditions for the sustainable development of the electric vehicle industry.

This year, Shandong Power Group will ensure that the Ximeng-Jinan-Nanjing UHV project will be approved and commence construction, and strive to be completed and put into operation in 2012. Shandong Power Grid will receive more than 10 million kilowatts of external power. A total of 65 intelligent substations of 35 kV and above and 56 substations will be intelligently reconstructed throughout the year. Newly-built substations of 35 kV and above that can be developed in the future will be built in accordance with the smart stations. All projects that meet the requirements will be based on the smart substation standards. Adjustment. It plans to build 2 new centralized charging stations, 6 power conversion stations and 40 battery distribution stations, expand 5 charging and switching stations, and build an electric vehicle operation management system before the end of the year to realize the smart charging and replacing of electricity service networks and the operating conditions of electric vehicles. real time monitoring.

Speeding up the development of distribution network automation. In April, the company formulated a unified distribution automation technology standard. In September, it established a demonstration area for high-reliability power distribution in Qingdao, and completed the construction of the Jinan distribution automation pilot project during the year. It will strive to complete Zibo, Yantai, and Weifang in the year. Jining, Linfen and other cities in distribution automation. In the whole year, 4.5 million smart meters were used and the coverage rate of low-voltage customer information collection reached 80%. In the next two years, 8.5 million smart watch replacements were installed in the province, and the direct user coverage rate for straight-area users was 100%.
