The scale of Shanghai Power Grid will increase by 50% over the next five years

According to the development plan of the State Grid, the “Twelfth Five-Year Plan” of Shanghai Power Grid has been initially completed and the main conclusions are being incorporated into the East China Power Grid Plan and the Outline of the Shanghai National Economic and Social Development Plan. In the next five years, the scale and throughput capacity of the Shanghai Power Grid will increase by 50%, and a first-rate urban power grid that is compatible with international metropolises will be built.

It is understood that in the next five years, the Shanghai Electric Power Company will implement the scientific concept of development in an in-depth manner to meet the power needs of sustainable economic and social development. It will strengthen the construction of ultra-high voltage as the backbone grid, coordinated development of power grids at all levels, DC strong backup, with information, automation, interactive features, strong and reliable, cost-effective, clean and environmentally friendly, transparent and open, friendly and interactive, reflecting the characteristics of Shanghai's leading international strong smart grid.

During the “Twelfth Five-Year Plan” period, Shanghai Power Grid will build two new 1000-kilovolt UHV substations with newly added capacity of 9 to 12 million kVA. By 2015, Shanghai Power Grid will have 15 500-kV substations, with 500-kV transformers reaching 40 and total substation capacity of 40.4-million kVA. The 220-kilovolt substation will reach 140, with a total capacity of 63.46 million kVA. Shanghai Power Grid will form a backbone network with two 1000-kV UHV substations and an existing 500-kilovolt double-ring network and an expanded south-and-a-half ring network. Through the optimization of the network structure and the improvement of the power throughput capacity, Improve the power capacity, transmission capacity, liaison ability and power supply capacity of the 500 kV main network in Shanghai, and achieve smooth connection and coordinated development between the 500 kV power grid and the UHV power grid.

In order to achieve safe, reliable, quality, clean, efficient, and interactive power supply, the Shanghai Power Company will gradually carry out the construction of smart substations from 2011 to 2015, and further promote the transformation and intelligent upgrading of substation integrated automation systems, and construct transmission lines and cables. State monitoring center, full implementation of transmission lines, cable condition maintenance. In terms of electricity use, it can basically build a smart electricity system, use electricity information collection system to achieve full coverage of electricity users, full information collection, comprehensive support for cost control, promote the construction of intelligent buildings and smart communities, and gradually increase virtual business services, self-service The proportion of applications in customer service is initially built into a strong smart grid that meets the city's electricity demand and reflects Shanghai's characteristics.

It is reported that during the “Eleventh Five-Year Plan” period, Shanghai Power Grid built five 500 kV substations including the Jing'an (Expo) substation and the Ting Wei (漕泾) substation, forming a double-loop (double ring network plus enlarged outer semi-ring) six-channel support 500 The KV main grid and 382 substations of 220 kilovolts and below have effectively safeguarded the economic and social development of Shanghai.
