ACT-II Wind Power – Electrical Testing and Commissioning

Project Overview

At ACT-II Wind Power Project, our team executed comprehensive electrical testing and commissioning for a 50MW wind power station, ensuring smooth integration with the national grid and long-term operational reliability. The scope included testing of power transformers, generator step-up units (GSUs), reactive power compensation systems, diesel generators, ring main units (RMUs), low- and medium-voltage cables, and the DC auxiliary system, all crucial for stable renewable energy delivery.

Testing Scope

The testing program covered a broad range of diagnostic procedures in line with IEC standards, including:

  • Power transformer testing: insulation resistance, winding resistance, turns ratio, short circuit impedance, and dielectric loss (tan delta)

  • Generator step-up unit (GSU) dynamic thermal and load tap changer performance testing

  • Reactive power compensation device testing for power factor stability and voltage control

  • DC system testing including battery banks, chargers, and distribution panels

  • Protection relay and control panel testing with simulated fault scenarios

  • Control wiring, panel interlocks, and RMU continuity and logic verification

  • Cable high-potential withstand and insulation resistance testing

  • Diesel generator load and no-load condition testing

  • Busbar and transformer stability testing under load fluctuations and fault recovery

Key Testing Procedures

Power transformers were assessed using Omicron CPC 100 and CP TD1 for insulation, winding resistance, turns ratio, impedance, and tan delta analysis. GSUs underwent dynamic thermal and load tap changer evaluations. Reactive power devices were tested for insulation, switching behavior, and power factor using specialized diagnostics. DC systems were checked for float voltage, capacity, and breaker operation. Protection relays were tested with Omicron CMC 356 simulating faults to verify trip logic and coordination. Diesel generators were evaluated for synchronization readiness and voltage regulation. Busbar and transformer stability tests ensured operational resilience under transient faults.

Project Significance and Impact

The project was delivered with full regulatory compliance, ensuring safe energization and grid integration. The successful commissioning of ACT-II Wind Power strengthens Pakistan’s renewable energy capacity and enhances grid stability. Our team’s expertise in renewable energy infrastructure underscores our commitment to quality and operational excellence in grid-scale commissioning services.
