Methodology for Determining Emissions of Pollutants During the Life Cycle of Wind Power Plants by Aggregated Data

Abstract

The paper sets forth a new method for determining emissions of pollutant during the life cycle of wind farms by aggregated data. The rationale for the use of aggregated data is given. Within the framework of method, an algorithm was developed for determining the emissions of CO 2 eq, SO 2 eq and PO 4 eq in the production of elements of wind turbines and wind farms. Classification of elements of wind turbines by parameters and technical characteristics of elements with subsequent division into groups is given. Formulas for calculating emissions of pollutant at the stages of the wind farms life cycle are given and substantiated. Within the framework of the method testing, emissions of CO 2 eq, SO 2 eq and PO 4 eq were calculated during the life cycle of two onshore wind farms with an installed capacity of 70 MW with wind turbines, differing in the parameters and technical characteristics of the elements. Calculated emissions of pollutants, which can be prevented when choosing the wind farms as power sources and determined the environmental effect of their use when comparing with thermal power plants.
