Job description

Key Responsibilities

• Deep understanding of customer (power plant owners) requirements (plant layout, monitoring & control requirements of power plant [Generator, GT, ST, Boiler, HRSG, BoP and Auxiliaries – respective open loop, closed loop controls and protection interlocks]), P&ID, and Functional Design Specifications
• Ability to understand and interpret P&IDs, Plant Layout and Control System Architecture, Functional Design Specifications, Control Philosophies & Control Narratives, Cause & Effect Matrices/diagrams
• Ability to design the entire control system software (system configuration, control logics implementation, HMI building and Alarm & Event Management) in collaboration with related technical departments.
• Well-versed with DCSs’ IO Databases, Alarm & Event Configuration, using HMI builder to create and link screens, control and interlock logic programming using Ladder Logic, Function Block Diagrams (FBD), Structured Text (ST) and Sequential Flow Charting (SFC). Experience and good understanding of IEC61131 based programming. Knowledge of Problem Oriented Language (POL) is a plus
• Knowledge of Network & Cyber Security Configurations
• Prepare system software configuration documentation. Review vendor documentation and technical submittals
• Knowledge of applicable international standards (IEC 61850, IEC60870, DNP3 etc.)
• Minimum of 5 years’ experience in design and detail engineering of one or more established DCS used in power plants. Example: Diasys Netamation, MELSEP, HIACS, TOSMAP, SPPA T3000, Mark VIe, Symphony Plus, 800xA, Emerson, Honeywell, Centum

Work Experience

• Very good understanding of control schemes and functionalities of controllers used for monitoring & control of Generator, GT, ST, Boiler, HRSG, BoP and Auxiliaries – respective open loop, closed loop controls and protection interlocks
