Can gas become electric?Chengdu Gas Pilot "Distributed Energy" helps to protect power supply

Since this summer, Sichuan has encountered extreme high temperature and drought weather, and the superimposed by many factors has led to the contradiction between power supply and demand. In order to win the tough battle of power supply, the whole society is working hard to deal with them together. On August 24th, the reporter learned from Chengdu Gas Group that in order to further allow the mall and other places to "let electricity in the people", Chengdu Gas Gas The natural gas distributed energy project piloted in Vientiane City, Chengdu Chenghua District, can use technical advantages to realize gas and electricity. The "conversion" effectively meets the power and cold demand of the mall under the independent power generation.

According to reports, in the distributed energy machine room on the first floor of the mall, there are 4 neatly arranged 1.5MW gas internal combustion hair motors in the mall. The natural gas cooling electricity connection system composed of Taiwan Fonil -type lithium bromide air conditioner and a CCHP intelligent control system converts the remaining energy to the cold energy supply.

In addition, the station has recently arranged personnel to keep the operating status 24 hours a day, and adjust the energy supply efficiency in a timely manner according to the changes in outdoor meteorological parameters. It is adopted at 7 am to 10 pm. The two generators were kept steadily at 10:00 to 7:00 the next day to ensure that the electrical and cold demand during the peak of the mall can be fully guaranteed.

It is reported that the system is the first large -scale commercial complex distributed energy project in Sichuan Province. It began energy supply in December 2020. The annual power supply can reach 25.4 million kWh and the comprehensive energy utilization rate of 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.
