Hello Members, I would like some clarifications regarding a few problems that occurred at our Wind power Plant which has installed Siemens Gamesa G114 (2.0-2.1MW) WTGs. The issues/matters requiring attention are as follows: Recently when the ambient temperature reaches around 35-40 degrees some WTGs trip due to temperature measurement module failure alarms or Top cabinet maximum temperature. If anyone of you is also facing a similar issue with this model, what countermeasures were taken to prevent this from happening and resulting in production loss. Boroscopy was carried out for the complete Plant and the findings concluded that multiple WTGs had pitting on their 'main bearings' ranging from moderate to severe. In a relatively new plant this defect raises severe concerns about equipment integrity. Is anyone else facing a similar issue with this WTG model. Furthermore, what solutions would be ideal/feasible to mitigate the operational effects of pitting (temp increases, vibrations, production loss), is there any workaround instead of a complete main bearing replacement. Any insights and hands-on experiences encountered regarding the following issues would be highly appreciated. Thanks in advance,
