Design and Implementation of a Real-Time Steam Turbine Alignment Monitoring System for Performance Optimization at Koradi Thermal Power Plant

The present study on the Steam Turbine Alignment Monitoring System demonstrates the significance of precise shaft alignment in ensuring efficient and reliable turbine operation. The analysis of CRO readings for LP1 and LP2 turbines shows that both units are operating within acceptable alignment limits. However, LP1 exhibits slightly higher variation compared to LP2, indicating minor misalignment that may lead to increased vibration and mechanical stress if not corrected. The calculated parameters, including mean value, Total Indicator Run-Out (TIR), and deviation, confirm that LP2 has better alignment stability and consistency. In contrast, LP1 requires fine adjustment to achieve optimal alignment and performance. Even small deviations can impact turbine efficiency, bearing life, and overall system reliability over time. The study highlights the importance of continuous monitoring, periodic alignment checks, and accurate data analysis for effective maintenance planning. Implementing such monitoring systems can reduce unplanned downtime, minimize maintenance costs, and enhance operational safety. Overall, the alignment monitoring system contributes to improved turbine lifespan, better efficiency, and sustainable power generation in modern thermal power plants.
