Selection of a 50kW Small Wind Turbine for Calgary

Abstract

The thesis studies the cost efficiency of wind turbines compared to photovoltaic (PV) technologies and develops criteria for the selection of cost-efficient and reliable small wind turbines for sites in Calgary. The thesis first presents a literature review of wind energy and turbines and describes the technicalities of large versus small turbines. It studies electrical generation, control systems, safety systems and certifications. This thesis analyzes the performance of PV and small wind turbines, and the economic differences between the two in terms of cost per unit power. Affordability is another advantage of Chinese turbines; they are usually cheaper than European. Since no Canadian manufacturers are running as Endurance went bankrupt, Chinese turbines are selected because they are relatively inexpensive, certified, and not much is known about them. A detailed framework compares technical and economic performances of turbines from different Chinese manufacturers.
