This document discusses the evolution of control systems at Egbin Power Station and the installation of a new Emerson Ovation DCS in 2014. It outlines the historical progression of control systems from 1985-2014, including the control components used for the boiler, turbine, and startup systems. The document then provides an introduction to the Emerson Ovation DCS, describing it as a state-of-the-art distributed control system developed by Emerson Process Management. It details the different interconnected systems that make up the Ovation trademark, such as the controller, I/O, network, workstations, historian, and alarm management system.

7. INTRODUCTION TO EMERSON OVATION
DCS
 It’s a trademark of Emerson Process Management and state-of-the-art
distributed control system (DCS).
 Ovation System, according to Emerson Process Management, is the World's
Most Reliable Control System – Ovation™ Optimized for the global power
generation and water/wastewater treatment industries. Ovation's field-
proven control design techniques developed over the last four decades
provide tighter, more precise and predictable control while a host of
advanced control and process optimization software allows client to further
enhance operations by automatically balancing the process for the
optimum results.
 Ovation is a body of systems that are independent, but interrelated. Below
are the different systems that make up the ovation trademark:
