Coordinator - Power System Study

Role Overview

Larsen & Toubro is seeking a Coordinator for power system studies based in Riyadh, Saudi Arabia. The role focuses on system studies for substations, renewable generation, grid interconnection, and industrial power networks. The ideal professional should bring strong hands-on experience in electrical network analysis, grid compliance, and study tools used for transmission and renewable integration projects.

Key Responsibilities

• Carry out power system studies for substations and renewable energy grid integration projects.
• Work on steady-state and dynamic studies such as transient stability, voltage stability, harmonic analysis, power quality, LVRT, and fault ride-through.
• Perform short-circuit analysis and support switchgear and circuit breaker sizing in line with applicable standards.
• Execute insulation coordination studies, including cable energization, transformer energization, reactor energization, TRV, lightning impact, very fast transient overvoltage for GIS, switching studies, power oscillation damping, and subsynchronous resonance studies.
• Conduct arc flash analysis according to international requirements.
• Support contingency studies for grid component design.
• Analyze ferroresonance behavior for transformers and EHV cables.
• Carry out secondary arc current extinction studies to enable successful auto-reclosing studies.
• Determine surge arrester duty, including residual voltage and energy level.
• Perform load flow assessments to identify overloaded network elements under renewable capacity addition scenarios.
• Identify reactive power compensation needs across multiple renewable integration scenarios.
• Model renewable sources, particularly solar, battery energy storage systems, and wind generation.
• Assess operational challenges associated with solar and wind technologies.
• Verify grid code compliance before plant energization across relevant operating conditions.
• Carry out motor acceleration and re-acceleration studies for industrial applications and motor groupings.
• Review available technology options in the market for conducting system studies.
• Estimate missing input data and parameters using project specifications and applicable standards when exact values are not available.
• Interpret country-specific grid codes, with preference for Middle East requirements.
• Propose optimization options while maintaining grid code compliance.
• Identify issues that may arise during grid integration and recommend corrective solutions.
• Support protection relay selection and coordination studies, including overcurrent, earth fault, unit protection, distance, motor, generator, and grid tie-in protection.
• Model phase-shifting transformers where required.
• Interact effectively with customers, utilities, and off-takers during approval of grid impact studies.
• Contribute to HVDC and STATCOM project studies, including electromagnetic compatibility-related evaluations.

Technical Environment

The role requires working knowledge of DIgSILENT, PSS/E, ETAP, PSCAD, HOMER, CYME, MATLAB, Mipower, EMTP-RV, CDEGS, and AVEVA.

Required Knowledge

• Strong background in power system studies for substations, renewable power plants, and industrial electrical networks.
• Good understanding of renewable generation technologies such as solar PV inverters and wind energy systems.
• Exposure to HVDC, FACTS solutions such as STATCOM, SVC, and SCG.
• Solid familiarity with IEC, IEEE, DEP, and other industrial standards.
• Ability to work with grid codes and utility approval processes, especially in the Middle East region.
• Hands-on experience with major power system study software platforms.
• Capability to evaluate engineering trade-offs and provide practical, standards-based solutions.
