This document provides an overview of the plant controls and instrumentation for the GGSR-Bathinda CPP plant in India. It discusses the control philosophy, instrumentation design, control system architecture, and primary and secondary control of major equipment. The control system uses a maxDNA DCS for monitoring and control of plant processes from the main control room. Instrumentation includes smart transmitters, mass flow meters, and radar level transmitters. Control of drives like pumps and valves is achieved through the DCS.
