REMAINING SERVICE LIFE FORECAST FOR WIND POWER PLANT TOWER
Rocket increase of number of WPPs in operation also means that each year more and more WPPs came to its passport service life end. And operating companies would aspire to reasonable extension of their exploitation.
WPP tower is one of critical components which are not replaceable unlike most of others and also a fragment of it could not be taken for destructive tests or laboratory tests. Flaw detection with non-destructive method is effective just for statement of the fact that flaw already appeared or now. It could not state anything regarding if the flaw will appear next day after inspection of after 10 years. This is important to alter priority of flaw detection to reliable forecasting.
Coercimetry of metal is exclusively efficient method of assessment of current fatigue state of wind power plant (WPP) tower metal.
This assessment allows to:
obtain the most reliable forecast of remaining service life based on metal state;
to uniquely determine if fatigue is among the reasons of failure for collapsed WPP;
to detect the less reliable WPP in operating windpark;
to state the reason of unreliability as zones of maximal fatigue and equipment;
manage wind power plant loading depending on fatigue state.
