Swiss technology company ABB has provided its Ability Symphony Plus distributed control system (DCS), an integrated automation solution to control the production of China’s first commercially operated concentrated solar power plant.
ABB’s Ability Symphony Plus DCS acts as the brain of the concentrated solar power plant and combines all the plant’s production processes, which include parabolic troughs, heat transfer system, molten salt tanks and the power block, into a single user-friendly system.
The ABB solution includes unique precision control of the parabolic troughs, which collect and intensify the heat. The control enables each one the parabolic troughs to harness maximum heat as the sun passes overhead.
Located at Delingha in central China, the 50MW concentrated solar power plant is operated by China General Nuclear Power Group.
The plant is part of the government’s initiative to establish concentrated solar power commercially and increase the country’s emission-free power generation capacity. The initiative aims to set up 20 such demonstration plants.
The Delingha concentrated solar power plant is the first to produce power under the Government’s concentrated solar power initiative and has also qualified for the maximum feed-in tariff.
Concentrated solar power uses the sun’s heat to produce steam and generate power. It has the ability to store the heat and use it at night as well.
ABB power generation and water business managing director Kevin Kosisko said: “This is a proud moment for ABB and for China General Nuclear Power Group.
“By completing the project to meet a very challenging deadline, we enabled the plant to maximise revenues and become the first to produce power in the government’s concentrated solar power initiative.”
Built on the sparsely populated region, the demonstration plant is expected to further strengthen China’s efforts to meet the 2030 target of producing 20% of its overall energy from renewable sources.
For this project, ABB’s scope of supply includes products, engineering, testing, installation supervision, commissioning of the solar field.
Its scope also includes providing commissioning support for the power block, and training.
