Manager - Testing & Commissioning - Wind Turbine Specialist

Testing & Commissioning Manager – (Wind Turbine Specialist) Position Overview This position is responsible for the planning, execution, coordination, and technical assurance of commissioning activities for Wind Turbine Generators (WTGs) in utility-scale wind power projects. The role ensures that mechanical, electrical, control, protection and grid-interface systems of WTGs are commissioned safely, operate reliably, and fully comply with OEM requirements, statutory regulations, and grid codes prior to handover. Detailed Core Responsibilities A. Engineering & Pre-Commissioning Planning - Review and provide inputs to engineering team to take care of engineering itself - based on experience. - Grid compliance and WTG controller limits - Machine specific challenges faced if any - Participate in FAT review of WTG control and protection systems (where - applicable). - Develop WTG commissioning procedures, method statements, and risk assessments. - Coordinate commissioning sequence planning with EPC, OEM, and grid operator. B. Mechanical & Electrical Commissioning Coordination - Supervise and verify correct completion of: - Mechanical erection, torquing, alignment, and lubrication - Electrical installation – LV, MV, transformers, grounding systems - Ensure readiness of auxiliary systems: - Pitch and yaw drives - Hydraulic and lubrication systems - Emergency and service power supplies C. Electrical Energization - Lead pre-energization checks including: - Insulation resistance tests - Grounding continuity - Sensitivity: L&T Construction Internal Use - Phase sequence and voltage checks - Coordinate transformer energization and LV/MV energization. - Execute first grid synchronization and progressive power ramp-up. - Ensure safety compliance during live tests and rotating machinery operation. D. Control, Protection & Grid Compliance - Validate WTG controller parameters as per grid code and PPC philosophy. - Coordinate LVRT / HVRT, frequency ride-through, and reactive capability tests. - Verify pitch-based power regulation and ramp-rate control. - Confirm correct response to curtailment, trip, and fault conditions. E. Trial Operation & Handover - Support trial run, availability tests, and performance acceptance. - Review SCADA data, alarms, and event logs. - Close commissioning punch points and support COD documentation. - Conduct knowledge transfer and basic training for O&M teams. - Testing, Commissioning & Troubleshooting - Responsible for commissioning and grid-compliance testing of wind turbine generators as - per IEC 61400-1, IEC 61400-21-1, IEC 61400-25, IEC 61400-27-1, IEC 60204-1, UL 6141 - and any other relevant standards Key Commissioning Tests - Insulation & dielectric testing of generators and transformers - Protection relay testing (OV/UV, OF/UF, differential, earth fault) - Functional testing of: - Pitch, yaw, mechanical brake - Emergency stops and fail-safe systems - Power curve and performance checks - Communication tests with plant SCADA and PPC Key Troubleshooting Scope - Grid-related trips (voltage/frequency instability) - Pitch or yaw control faults - Excessive vibration or temperature alarms - Transformer or converter faults - Communication failures between WTG and PPC Key Competencies & Skills - Strong understanding of WTG electrical & control systems. - Familiarity with IEC 61400 series and grid code requirements. - Ability to analyze turbine event logs and operational trends. - Experience coordinating multi-disciplinary OEM teams. - High safety awareness for rotating equipment and work at height. Minimum Qualifications - Bachelor’s Degree – Electrical / Mechanical Engineering. - 12–15 years of WTG commissioning experience. - OEM commissioning authorization strongly preferred. - Certified Engineer. Qualifications: Bachelor Program in Mechanical Engineering Experience: 10-12 years

Bachelor’s Degree – Electrical or Mechanical Engineering. 12–15 years of WTG commissioning experience. OEM commissioning authorization strongly preferred. Certified Engineer.

A. Engineering & Pre-Commissioning Planning: Review inputs, ensure grid compliance and WTG controller limits, participate in FAT reviews, develop commissioning procedures, coordinate sequencing with EPC, OEM, and grid operator. B. Mechanical & Electrical Commissioning Coordination: Supervise mechanical erection, torquing, alignment, lubrication; electrical installation (LV, MV, transformers, grounding); ensure readiness of auxiliary systems (pitch/yaw drives, hydraulic and lubrication). C. Electrical Energization: Lead pre-energization checks (insulation resistance, grounding continuity, phase/voltage checks); coordinate transformer and LV/MV energization; execute first grid synchronization and power ramp-up; ensure safety during live tests. D. Control, Protection & Grid Compliance: Validate controller parameters per grid code and PPC philosophy; coordinate LVRT/HVRT, ride-through, reactive capability tests; verify pitch-based regulation and fault responses. E. Trial Operation & Handover: Support trial runs and availability tests; review SCADA data; close punch points and support COD documentation; conduct knowledge transfer and basic training for O&M teams. Testing, Commissioning & Troubleshooting: ensure commissioning and grid-compliance testing per IEC standards mentioned; perform insulation tests, protection relay testing, functional testing of pitch/yaw/mechanical brakes, emergency stops, and SCADA communications. Key Troubleshooting: address grid trips, pitch/yaw faults, excessive vibration/temperature alarms, transformer/converter faults, and SCADA/PPC communication failures.
