Abstract


This paper presents the comparison for a small scale wind farm which is composed of singly fed induction and doubly fed induction wind turbine generator systems. The singly fed induction generators are actually largely depended on reactive power, particularly when a fault occurs in the power system, otherwise such induction wind turbine generator become unstable and have to be disconnected from the power system. In this paper, a wind farm topology is considered, where connected wind turbine generator is represented by a doubly fed induction generator, which controlled by a back to back converter. No extra power or current control loops are required, this simplify the system design and improve transient performance of the whole system. Simulation results clearly show that the proposed topology is a cost effective solution and simplify a system design to minimize voltage fluctuation of both wind turbine generators as well as to improve the transient stability of the wind farm.
