PMSG Wind Turbine System for Residential Applications


This paper analyzes the operation of small wind turbine system with variable speed Permanent Magnet Synchronous Generator (PMSG) and a Lead Acid Battery (LAB) for residential applications, during wind speed variation. The main purpose is to supply 230 V/50 Hz domestic appliances through a single-phase inverter. The required power for the connected loads can be effectively delivered and supplied by the proposed wind turbine and energy storage systems with an appropriate control method. The models of the PMSG, boost converter with a control method for obtaining maximum power characteristic of wind turbine (MPPT), voltage source inverter (VSI) and LAB model with battery state of charge (SOC) control method, are presented. Energy storage devices are required for power balance and power quality in stand alone wind energy systems. Simulations and experimental results validate the stability of the supply.

In this paper, a PMSG wind turbine system for residential applications is analyzed. Simulation and experimental results show that the active power balance of the system proves to be satisfying during variable wind speed condition. The MPPT algorithm will ensure a maximum extraction of energy from the available wind. LAB always ensures the safe supply of the loads (households) regardless of the problems caused by wind speed variations. At the end one can conclude that the power system’s stability considered in terms of load power quality can be ensured by using the proposed configuration.
