China's first smart grid integrated demonstration project completed in Tianjin

China's first smart grid integrated demonstration project was successfully put into operation in the China-Singapore Tianjin Eco-City on the 19th.

The demonstration project with a coverage area of ​​31 square kilometers and 12 sub-projects covering 6 major links is currently the world's most extensive and most fully-functional smart grid system. The implementation of intelligent systems will not only enable renewable energy utilization ratios such as wind power and photovoltaic power generation to reach more than 20%, but also the integration of power grids with cable television, IP telephony and the Internet, and the intelligentization of remote control, telemetry and information feedback can be covered. Resident life, public facilities and industrial production.

Wang Yimin, director of the Smart Grid Department of the State Grid Corporation of China, introduced that the smart grid project of China-Singapore Tianjin Eco-City involves six major stages of power generation, transmission, substation, power distribution, electricity use, and dispatch. During the implementation of the project, Tianjin Electric Power Company cooperated with more than 20 research institutes at home and abroad, exchanged views with hundreds of experts and scholars from nearly 30 countries and regions, and completed 4 original systems and 8 technical support systems such as electric integration. Developed and formulated 39 management specifications and technical standards for micro-grid dispatching operations.

According to reports, compared with traditional substations, smart substations reduce the area occupied by 10.9% of 110kV smart substations, reduce the building area by 11.2%, and reduce the use of secondary cables by 41.4%.

Sino-Singapore Eco-City is a major cooperation project between the governments of China and Singapore to cope with global climate change, conserve resources and energy, and build a harmonious society. It was groundbreaking in September 2008 and is expected to be completed in 10 to 15 years. Sino-Singapore Eco-city learns from the successful experiences of Singapore and other advanced countries and regions, and has determined 22 control indicators and 4 guiding indicators, of which green buildings reach 100%, green travel ratio is not less than 30%, and renewable energy use rate is not Less than 20%.
