Abstract

Abstract: As wind power penetration has been gaining in the power grid for decades, a large number of the doubly fed induction generator(DFIG) based wind farms are being established around the globe. The power capacities of these wind farms may vary around hundreds of MW, and most of the wind farms are connected to long transmission cables whose impedances can not be ignored and require careful attention. Several works have investigated the impedance interaction between the DFIG based wind farm and long transmission cables which may unfortunately cause high frequency resonance (HFR). The main contribution of this paper is to investigate the influence of the variable wind farm capacity on the behavior of the HFR when certain transmission cables are provided. It is found out that the potential HFR may happen in certain wind farms, and the larger wind farm capacity causes more severe HFR due to the relatively weaker grid transmission capability. Simulation results based on Matlab/Simulink are given to validate the analysis of HFR.

Key words: DFIG based wind farm, variable power capacity, long transmission cable, high frequency resonance
