Abstract

Wind turbine farms are an effective generator of electricity in windy parts of the world, with prices progressing to levels competitive with other sources. Choosing the correct turbine for a given installation requires significant engineering and the current trend leads towards groups of large horizontal axis turbines. Unfortunately, large wind turbines have to contend with large forces and other sources of failure. With the new push to move generation farms offshore where they are less accessible, the issue of reliability becomes more critical. This work investigates the impact of reliability in a life-cycle analysis simulation of a theoretical wind farm in Massachusetts based upon reliability information from a number of academic sources. The simulator, TurbSim, is designed with significant modularity to enable reliability simulation of any turbine with available wind information. Our simulation of a turbine indicated that reliability makes a small but noticeable impact of 1.24% in its output.
