Analysis and comparison between two wind farms consisting of 500kW midsize turbines and 1.5MW turbines

摘要

This paper compares the characteristics of two wind farms of same power capacity having two different size generators. The research compares the performance of mid-size turbines to large turbines. The systems were modeled in MATLAB-Simulink. With rapid development in wind power generation it's necessary to study the different characteristics of wind farms having different generator configurations. A 9MW wind farm consisting of eighteen Fixed Speed Induction Generators (FSIG) with STATCOM at the terminals of the wind farm is compared to a 9MW wind farm consisting of six Doubly Fed Induction Generators (DFIG) interfaced with Power Electronics on the rotor. The models of FSIG wind power generation system and DFIG wind power generation system connected to the grid are built. An analysis on total power available for transmission, reactive power consumption at different wind speeds (cut in, rated, cut off), power loss due to loss of turbines.
