"The self-check of the energy storage device is passed, and the grid connection procedure is started".
"The first switch is switched successfully, and the grid connection is successfully completed!" With the issuance of instructions, the data on the large screen in the control room of Weizhou Terminal Energy Storage Power Station moved up, and the continuous current was transmitted to the offshore oil field group power grid through the energy storage device
.
On September 20, the full capacity of China's first energy storage power station applied to the offshore oilfield group power grid was integrated into the southwest oilfield group power grid. The energy storage power station is located in the terminal treatment plant of Weizhou Island, Beihai City, Guangxi, CNOOC, covering an area of about 500 square meters.
The power station consists of two sets of 2.5 MW air-cooled energy storage systems with a total of 11200 batteries, a single container weight of about 56 tons, and a total energy storage capacity of 10000 kilowatt-hour . After the energy
storage power station is put into operation, the power grid of Southwest Oilfield Group will consist of five gas-fired power stations, one waste heat power station, one photovoltaic power station and one energy storage power station. The total installed capacity is 112 MW, which shoulders the important task of supplying power for oil and gas production in Southwest Oilfield Group and people's livelihood and tourism in Weizhou Island. The energy storage power station
put into operation this time consists of two sets of 2.5 MW-2 hours air-cooled energy storage systems in parallel. From the outside, they are four white container-like cubes, each consisting of a battery container and a converter booster system. Gao Chuanlian, the
project leader, said that the battery of the energy storage power station uses the current mainstream lithium iron phosphate single battery, and the battery container is similar to a "power bank", which is responsible for power storage. Each battery can store 5000 kWh of electricity; The direct current released by the battery is converted into 35 kilovolt alternating current matched with the power grid through the converter and booster integrated machine, which is integrated into the power grid.
