Dear all,
Our gas turbine is frame 9fa with dln 2.6+
When gas turbine was operated few months back the unit corrected output is around 210 mw (gross mw is 228 mw), and recently we did the baseload test. this time the corrected output is around 206 mw (gross mw is 233 mw), to compare and know what could be the reason for drop in corrected output. i was confused as recent time gross generation is more and seems all parameters are okay. however its due to ambient conditions. but once its corrected to the site conditions, the unit output should be closer to the previous base load test results. what could be the reasons for drop in gas turbine 4 mw load.
gas turbine base load operation is when gt is in combined cycle operation only, as there is 4 mw drop in gas turbine output steam turbine output also reduced.
please suggest me the parameters which i need to look into so that i can spot the reasons for drop in mw. i mean how to start the root cause analysis. i can provide whatever the data you want.
