The article analyses information on the state of equipment of heat power plants in Ukraine. Researched probability of fault of main elements of synchronous generators. Defined elements of synchronous generators, which need take more attention and parameters, which will be monitored all time. Proposed for early identification of elements faults of synchronous generators using methods of online diagnostic. Analysed of faults detection at different levels of diagnosis: major overhaul, limited inspection, safety check, online. Take to account of results this analysed decide try to create fault tree analyses synchronous generators. In 2018 in Ukraine, it was showed that the technical state of the energy industry infrastructure is approaching critical due to the high degree of equipment wear and tear, lack of technology, lack of sufficient investment, namely \u201cat most power plants the equipment design resource is already exhausted and is being used beyond the operational lifetime. For example, out of 75 generating units of heat power plants companies, 68 units (16962 MW or 78.7%) are operated over the park lifetime, 2 units (600 MW or 2.8%) are operated over the operating lifetime and 5 units (4 000 MW or 18.6%) is operated over the projected lifetime. Take to account of results this analysis we decide try to create tree of analysis fault of synchronous generators, using data from normative documents and experience operative personal.
