An Optimal Method for Sensorless Control of DFIG based WECS using PSO


Objectives: A sensorless method is employed to control real and reactive power for DFIG in an optimal way under various load conditions. The main objective of this paper is to maintain constant voltage and constant frequency. Method/Analysis: In this paper, a sensorless control technique with the optimal Proportional-Integral (PI) controller parameters of a test system using Particle Swarm Optimization (PSO) is explained. The techniques for the development of sensorless drives are: reduction of hardware complexity and cost, decreased maintenance requirements, elimination of sensor cables. Optimal tuning of PI controller parameters gives high quality solution. Findings: The system performance with PI controller parameters and PSO tuned PI controller parameters are compared. MATLAB software is used to develop the simulation and the results are presented. Applications: Low Voltage Ride Through, Lvrt, OFFSHORE wind farms.
