Under the first contract, Emerson will modernize the controls for the steam turbine and turbine drives for feedwater pumps at six 500MW units (Units 3-8). Emerson’s Ovation technology will monitor and control the Turboatom turbines at two of the units and LMZ turbines at the other four; as well as two KTZ turbine drives for feedwater pumps at each unit.
The contract also includes retrofitting the turbine protection system and turbine digital electro hydraulic (DEH) system. The controls upgrade for two of the units will be completed in 2010, and the other four will be finished in 2011-2012.
Emerson claims that utilizing a single Ovation platform to control equipment supplied by different turbine manufacturers will help Ekibastuz GRES-1 streamline operations and improve overall efficiency by reducing the need for training and spare parts.
Under the second contract, Emerson will digitally automate all major equipment and processes, including unit coordinator and startup and shutdown sequencing at Unit 8. In all, Ovation will monitor and control 5,000 I/O points at this unit, which is scheduled to return to service in 2012.
Over the next five years, Ekibastuz GRES-1 also plans to extend the scope of Ovation’s control at Units 3-7 to provide unit coordinated control and opportunities for additional process optimization.
