DTC Leading Edge Seminar Series

Getting the Most out of Wind Farms: Role of Data Analysis and Monitoring


Girija Parthasarathy

3:30 p.m. reception
4:00 p.m. seminar

401/402 Walter Library

Wind turbines often operate in severe, remote environments and require frequent scheduled maintenance. The cost of unscheduled maintenance because of undetected failures is high both in maintenance support and lost production time. The continuous automated monitoring and data analysis of condition-based maintenance (rather than hours-based) enables high reliability and low maintenance costs. The talk will cover the topic of health monitoring of wind turbines, as accomplished in a recently completed DOE program led by Honeywell. The objective of the CBM for Wind Farms program was to develop a dual approach of vibration and performance monitoring to assess wind turbine health and initiate early response to developing failures. Vibration monitoring checks for failure precursors in high-value drive train assets—including gearbox, main shaft, and generator bearings. Performance monitoring detects anomalies, failures, and performance degradation issues in the wind turbine as a whole, using different fault diagnostics algorithms. Our team included Honeywell, Juhl Wind, NREL, and PNNL.


Dr. Girija Parthasarathy is a Research Scientist and Program Manager at Honeywell Automation and Control Solutions. She has served roles of principal investigator and program manager in several diverse government and Honeywell funded programs. Her technical experience spans Prognostics and Health Management for Wind turbines, turbine engine diagnostics and prognostics, microgrid modeling and optimization, combined heat and power, combustion and district energy. Most recently, she directed a DOE program on Condition Based Maintenance for Wind Farms, which led to the development of novel, yet simple, monitoring approaches. In her prior role at Honeywell Aerospace, she has led the development of innovative technologies for turbine engine life monitoring, which found application in the Joint Strike Fighter Power Thermal Management System PHM program. Dr. Parthasarathy has authored several conference and journal papers. She currently conducts a program for optimization and control technologies application in microgrid and smartgrid domains.
