ABB will supply the complete process control system for units 3 and 4 of the Hui Lai thermal power plant. Located in the Guangdong province of China, the plants are owned by the Guangdong Yudean Group. Each of these units have generating capacity of 1,000 megawatts and are designed to set new efficiency standards in the country.
ABB's scope of supply comprises an integrated control system, including boiler protection, turbine control, flue gas desulfurisation, common auxiliary electrical systems and central control room. ABB is also responsible for engineering, installation and commissioning. The units are scheduled to start production in 2011.
"ABB's latest control platform technology and extensive domain knowledge of power generation processes will go a long way towards ensuring reliable plant operation with minimised maintenance and operating costs," says Franz-Josef Mengede, head of ABB's power generation business.
ABB previously supplied control systems for units 1 and 2 of the plant with a similar scope. These 600-megawatt units have been in successful operation since 2007.
According to ABB, their common control technology for the four units reduces the need for training and the cost of maintenance and spare parts, in addition to improving operator efficiency and plant safety.
