Abstract:As the global operational wind turbine fleet ages and a trend towards self-operations is observed by wind farm operators, research into reducing the levelized cost of electricity continues. Operation and maintenance costs have a substantial contribution to the levelized cost of electricity. Furthermore, offshore wind turbines operate in a harsher environment which makes it harder and costlier to execute maintenance. Therefore, high downtimes and high maintenance costs can be observed which inadvertently results in a higher levelized cost of electricity. With reliability information provided by Fraunhofer, we have analyzed and proposed an optimal maintenance policy for a single component which minimizes maintenance cost and thereby ensures reliability. The component chosen for this research purpose is the converter system. The converter system fails frequently and has a high share on the annual downtimes. Furthermore, the optimal preventive replacement time of a rotor system in an offshore wind turbine has been analyzed and proposed.
