Rectification of High Vibration at Bhira Hydro Station

Complete Overhauling and Vibration Rectification

Client: Maharashtra State Power Generation Company Ltd. (Mahagenco)
Location: Bhira Tail Race Hydro Power Station, Maharashtra

Introduction

Corpex Power LLP operates primarily in the power generation and engineering services sector, specializing in power plant maintenance and optimization in both Hydro and Thermal. The company focuses on delivering end-to-end solutions for turbine-generator (TG) sets, including vibration rectification, dynamic balancing, and installation of advanced monitoring systems.

Beyond maintenance, Corpex Power LLP is committed to innovation in power generation operations, offering custom-designed tools and lifting devices for complex overhaul projects. Through strategic partnerships and resource mobilization, Corpex ensures timely execution of critical projects, minimizing downtime and enhancing the lifecycle performance of power generation assets.

Team Corpex

Ranesh Gaur – Director - Technical

Suhas Bhoge – Director - Operations

Background

The Bhira Tail Race Hydro Power Station Unit No. 2 (40 MW) faced a critical challenge of high vibration levels in its hydro turbine generator (TG) set, which threatened operational stability and efficiency. MAHAGENCO entrusted us with the responsibility of rectifying this issue through a comprehensive overhaul and vibration reduction program.

Initially, Corpex agreed to do minor rectification work, during which vibrations were reduced significantly in just 6 days. Root cause analysis indicated a combination of mechanical misalignment and electrical imbalance.

Critical Metric achieved 2,333 → 277 Microns

Reduction of overall vibration levels well within OEM limits.

Execution and Technical Excellence

The successful execution earned Corpex Mahagenco’s trust and led to the award of a larger project involving the complete overhauling of the unit. A team of experts was promptly mobilized, including specialized professionals from BHEL and TATA Hydro.

Key Technical Activities:

  • Cryogenic Cleaning Dry ice blasting to clean the stator without damaging insulation.
  • Precision Coupling Hydraulic torque wrench for accurate mechanical integrity.
  • 100% Blue Matching Thrust pad alignment for perfect contact and stability.
  • 3D Mapping Digital mapping of critical parts for future audits and maintenance.
  • Electrical Testing International standard tests (continuity, surge) for stator/poles.
  • Smart Monitoring Vibration Monitoring System (VMS) for real-time tracking.

Performance Metrics & Results

The installation of a Vibration Monitoring System (VMS) provided real-time monitoring and predictive maintenance capability.

These efforts culminated in the successful synchronization of the unit and one-month operational stability testing, meeting all OEM standards and contractual performance guarantees.

Challenges and Adjustments

  • • Complex Mechanical Constraints: Handling the generator rotor required custom lifting devices, designed and manufactured under tight timelines with software-based load tests.
  • • Space and Safety Limitations: Working within confined spaces demanded strict adherence to safety protocols and innovative handling techniques.
  • • Resource Mobilization: Immediate deployment of multi-disciplinary experts was essential to meet deadlines.
