Chengdu gas distributed energy autonomous power generation reduction power supply power supply pressure

A few days ago, the people in Chengdu were brushed by a news: This summer, every time in Sichuan was not easy! Since August, under the three "most" influence of the highest extreme high temperature in the same period, the minimum precipitation of the same period, and the highest power load in the same period, the pressure of the operation of Sichuan Power Grid was approaching the limit. In this case, Chengdu Gas Group Co., Ltd. ’s natural gas distributed energy projects invested and operated by Vientiane City, China Resources Chengdu make full use of special technical advantages such as“ integrated optimization ”to effectively meet Vientiane City under independent power generation. Electricity and cold demand.

In the underground distributed energy machine room of Vientiane City, four neatly arranged 1.5MW gas internal combustion hair motors are rotating smoothly and efficiently. While using natural gas combustion for power generation, it also connects 4 flue gas -type lithium bromide air conditioners. A natural gas cooling power connection system composed of a CCHP intelligent control system converts the remaining energy into cold energy supply. In addition, Chengdu Gas Maintenance Limit During the high temperature period, the personnel at the distributed energy stations are on duty to run the operating status for 24 hours, and adjust the energy supply efficiency in a timely manner according to the changes in outdoor meteorological parameters. All air -conditioning was put into operation, and the two generators were kept steadily at 10pm to 7 o'clock the next day, and they made every effort to ensure the demand for electricity and cold during the peak of Vientiane City.

Chengdu Gas Distributed Energy Project not only plays a peak -to -peak -to -valley role in power grids, reduce the power supply pressure of the grid, but also fully highlights the significance of energy complementarity and diversification of energy.

Under the country's multi -energy complementary policy policy, Chengdu Gas has actively promoted and implemented the distributed energy project of Vientiane City, and has declared the Chengdu distributed energy demonstration project. This project is a pilot project of distributed energy in Sichuan Province. The total investment of the project is 53.92 million yuan. It is the first large -scale commercial complex distributed energy project in Sichuan Province. The energy supply began in December 2020. The annual power supply can reach 25.4 million KWH. Comprehensive energy utilization rate is more than 80%. At the same time, the project uses a number of national patents such as flue gas heat deepening recycling technology, unit structure compact technology, adaptive control technology, self -heating constant temperature control technology, and intelligent control system technology. The energy utilization model of production, that is, uses natural gas as the main fuel to drive the operation of the power generation equipment, the power supply households generated, and the remaining heat excreted after the power generation can heated and cool the user through the residual heat recovery equipment , Realize the use of energy steps.

According to statistics, Vientiane City's electricity load after limited to 30%is about 4300kW, and distributed energy projects can be powered by 6000kW, which can reach 72%of the power load during the normal operation period. Cold energy supply; most of Vientiane City's power demand can be met, and the central air conditioner continues to run.

According to the "Implementation Opinions of the National Energy Administration of the National Development and Reform Commission on Promoting Multi -Energy Complement and Integration Optimization Projects", Chengdu Gas Accelerating the implementation of distributed energy, comprehensive energy and other projects, improve terminal station management, and actively explore "double carbon" In the context, the distributed energy project business continues to help the city's long -term efficient and stable development. At the end of April 2019, the distributed energy stations of the Haida Rubber were put into operation; in early December 2020, the Duanxiang City distributed energy stations were debugged and put into use; in mid -June 2022, Tianfu International Health Service Center Energy Station was launched normally ...

Compared with traditional energy supply methods (municipal electricity+gas boilers+electro -refrigeration machines), three distributed energy systems such as Haida Rubber, Vientiane City, and Tianfu International Health Service Center are obvious. The standard coal is about 17,562 tons, and the annual CO2 emission reduction is about 34433 tons.
