The Study on the Reliability of the Collection System of the Offshore Wind Farms Considering the Electrical Faults and Switchgear Configurations

Abstract:

With the rapid development of the offshore wind power, the design of the collection system for offshore wind farms attracts widespread attentions. In this paper, on the basis of analyzing the connection property and switchgear configurations of collection systems of offshore wind farms, a comprehensive reliability assessment model and the corresponding calculation method for the traditional switchgear configuration and the complete switchgear configuration are proposed. Taking an actual planned offshore wind farm for example, the reliability of two switchgear configurations are evaluated, and the sensitivity analyses on factors affecting the reliability of the wind farms such as the failure rate and MTTR of the cables and switchgears are performed. The result shows that the complete switchgear configuration is the better choice for offshore wind farms considering reliability indexes.
