Abstract:

This paper presents the design of Shunt Active power filter and simplified control of hybrid system (wind –hydel) system connected to two back-to-back converters in which one is connected to hydel turbine and the other is connected to wind turbine system through squirrel cage induction generators (SCIG) feeding three phase loads in isolated locations. The main objective of this work is to provide a better control algorithm for the VSC and to achieve maximum power tracking (M.P.T) through rotor speed control of the wind turbine driven S.C.I.G under varying speeds at the machine side and to control the magnitude and frequency of the voltage at load side and to eliminate the ripple content in the wave forms and to create the system balanced. The system also ensures in sending the power generate by SCIGw is complete to the load through the load-side converter and remaining power be store into ESBS. And at the identical time if the required active power of the load is more than the total power generated by SCIGw and SCIGh. Then the deficit power is supplied by the ESBS. Simulation models of the proposed hybrid system with SAPF and the simulation results are obtained in MATLAB using Simulink and Sim Power System set toolboxes, with different load condition at different wind conditions.
