reporter learned from Yunao Co., Ltd. that part of the electricity used in the aluminum smelting and production in Yunao Yang Zonghai plant is from solar energy.
At 10:40 am on September 28, with the electrolytic aluminum busbar DC output circuit breaker closed, the 300-kilowatt DC access equipment test project of the second phase of the green smart energy project of Yunao Yang Zonghai Green Aluminum Industrial Park Green Aluminum Industrial Park Green Smart Energy Project was successfully put into operation. This is the first test project in the country to directly supply aluminum smelting and production of photovoltaic DC power to date, marking a major breakthrough in photovoltaic power generation DC connection to electrolytic aluminum production, and will provide experience and demonstration for domestic green electricity conversion and new power systems.
Most electrolytic aluminum enterprises in my country use large power grids to supply power to electrolytic cells, and the power conversion process is numerous and complex, and the power loss is serious. Previously, Yun Aluminum Co., Ltd. and Yunnan International and other professional units continued to carry out green energy project cooperation, and discussed the implementation path of the DC busbar of the photovoltaic DC direct supply cloud aluminum electrolytic production line many times. After repeated tests and verification, many scientific research problems such as unstable photovoltaic power generation efficiency and inability to ensure that the DC current constant current output is connected to the DC busbar of the cloud aluminum electrolytic production line are successfully overcome and solved.
According to the plan, the green smart energy project of Yunaoyang Zonghai Green Aluminum Industrial Park can utilize the roof area of the industrial park with a total installed capacity of 37.85 megawatts. After the second phase of the project is completed, the installed capacity of photovoltaic green power in the park will reach 51.6 megawatts, providing about 63.98 million kilowatt-hours of green clean electricity every year, saving 19,500 tons of standard coal per year, reducing emissions of 258,200 tons of carbon dioxide per year, and reducing emissions of 17.25 tons of sulfur dioxide, nitrogen oxide and smoke.
Yun Aluminum Yang Zonghai Green Aluminum Industrial Park Photovoltaic power generation DC connection to electrolytic aluminum production electricity. The relevant person in charge of
Yun Aluminum Co., Ltd. introduced that at present, the project has achieved electrolytic series and photovoltaic DC interconnection power supply and distributed photovoltaic on-site absorption, improving the renewable energy utilization and energy efficiency level of the electrolytic aluminum industry, providing technical support for direct green supply, and is a case of providing significant innovative application value for the green development of electrolytic aluminum. Next, Yunao Co., Ltd. will base itself on the new development stage, implement the new development concept of , deepen cooperation with Yunnan International and related parties, and continue to promote the research and implementation of key technologies for distributed photovoltaic DC access in the green smart energy demonstration project of Yunao Yang Zonghai Green Aluminum Industrial Park, and create an innovative model of green energy integration.
