Measurement of temperature flow analysis by condition monitoring system for WTG gear box to evaluate the thermal performance associated with plant load factor

Abstract

This research work is mainly focused on the performance of the wind turbine power plant. The performance of the plant will depends on the working of wind turbine gearbox. Hence the parameters taken like inlet velocity of air, inlet temperatures and inlet pressure of the air entering into the gearbox. For experimentation a three stage gearbox has been considered and the data has been recorded for the period of 5 months. These results has been recorded with the help of SCADA software and the results are imported from SCADA for analyzing the minimum and maximum oil temperatures. Since these parameters effects directly on the thermal performance of the wind turbine power plant. From the analysis it was found that the temperature sensors for monitoring the oil TM1 and TM2 within temperature limits of 250οC and also the TS1 and TS2 Promises the sensing capacity within temperature limits up to 200 οC and response time is 30 minutes, also the coupling temperatures TC1 and TC2 gives very promising results upto 150 οC for 30 minutes response time.
