Process control and instrumentation of SeSWRS based hydrogen cooling system of thermal power stations: A 2×660 MW unit

The paper presents a `Seven Stage Warm Redundant Structured' (SeSWRS) hydrogen cooling system (HCS) for generators cooling in a typical thermal power station. The proposed system is equally reliable for steam and gas turbine based generating sections. System reliability of the proposed SeSWRS model is evaluated using MATLAB. The process control and instrumentation of the system is designed and simulated on Factory-Talk ViewSE, a supervisory control and data acquisition (SCADA) platform by Rockwell automation. The process model is designed as per specifications guided by IEEE C37.1-2007; IEEE 1413-2010, and ISA 100a.
