Reliability Evaluation of Wind Farm Considering Component Faults in Collecting System
In view of the significance of the reliability evaluation of wind farm operation during the planning phase,taking the active power output of wind farms as the object study,based on the analysis of the topology structure and component reliability model of wind farm collection systems,considering the influence of wind speed changes on system reliability indicators,this paper designs a wind farm reliability evaluation process combining sequential Monte Carlo method and depth first path search method.Afterwards,the reliability indicators of wind farms under different topology structures are compared and analyzed through examples.The results show that comparing with the radial topology,the equivalent outage rates of wind farms using single-sided ring topology and double-sided ring topology are reduced by 7.92%and 7.79%,respectively.The reliability of single-sided ring topology is the highest,and the established reliability model and evaluation method are effective and reliable.
