Ambarli A consists of three, 450-MW power blocks, each in a 2x2x1 configuration, with a total generating capacity of 1,350 MW. Under the contract, Emerson will replace existing controls with its Ovation™ system, which will control more than 20,000 I/O points in all. Ovation technology will directly control and provide overspeed protection for the plant’s six Siemens V94.2 gas turbines. The system will also control three Siemens dual-pressure condensing steam turbines, heat recovery steam generators and balance-of-plant equipment and processes.
Emerson will also install its Ovation SIS for SIL3 turbine protection and emergency shutdown systems and perform a complete digital electro-hydraulic control system rehabilitation for the third block’s gas turbines. Emerson will also provide engineering, design, installation, commissioning and startup services. The project is expected to be completed by March 31, 2018.
