Development of a Quality Management System for Electric Power applied to Small Wind Turbines

Abstract

This paper presents a methodology for calculating and monitoring power quality using discrete signal processing techniques, enabling the detection and quantification of electromagnetic disturbances in transient and steady state time periods. The limits of power quality disturbances that will be monitored are defined by international norm (IEEE 1159). Together with the power quality monitoring system, a power quality assessment was implemented by changing the input variables of the generator in order to restore the standards of the power grid (voltage, current and frequency). The proposed system is a management system, able to identify, quantify and monitor the power quality and can be used as a diagnostic tool for maintenance and a control system for decision-making to reestablish the generation system.
