## Description

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

## Requirements

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