Maintenance Management of Wind Power Systems Using Condition Monitoring Systems—Life Cycle Cost Analysis for Two Case Studies

Modelling and simulation of operation and maintenance strategy for offshore wind farms based on multi-agent system

“…It depends on several parameters such as the failure types, the maintenance types, the maintenance duration, the weather conditions, and the cost of the maintenance facilities [34].…”

“…The same team has proposed to use reliability centred maintenance to wind turbines [18]. Nilsson et al [34] present the approach used for operation and maintenance at two companies, Swedish Vattenfall and Danish Elsam, and propose the improvement of maintenance strategy using Condition Monitoring Systems. [8] and [33] have put forward a strategy based on the risks and costs of avoiding corrective maintenance.…”

A brief status on condition monitoring and fault diagnosis in wind energy conversion systems

“…Moreover, redundant measurements provided by the wind farm (e.g. wind speed) will be used to improve the overall wind farm performance by minimizing operational losses due to anemometer failures [6], [35].…”

“…Moreover, condition monitoring will also detect extreme external conditions, such as icing or water induced tower oscillations of offshore plants, and can trigger appropriate control actions to prevent damage of plants components. This way, overall maintenance costs and downtime of wind energy converters can be significantly reduced [2][3][4][5][6]. Fig.…”

Reliability analysis for wind turbines with incomplete failure data collected from after the date of initial installation

“…Walford outlined the issues relevant to wind turbine reliability for wind turbine power generation projects and the relationship between wind turbine reliability and operation & maintenance costs [1] . Reliability and condition monitoring apparently benefit the maintenance management of wind power systems [2] by reducing the O&M costs by giving advance warning of failures. Some authors have combined wind power generation and wind speed models to analyze power production reliability [3] [4] .…”
