Dynamic Voltage Control of Wind farm Using Thyristor Control Inductive Filtering Method

Abstract

In the proposed concept fully tuned inductive filtering has been implemented; to enhance power quality thyristor controlled inductive filtering can be implemented.

Nonlinear loads cause significant harmonic currents with poor input power factor(PF),which create serious problems at the power supply system. Traditionally, passive filters have been used to eliminate current harmonics of the supply network. Recently, thyristor-inductive filters (TIF).which contain several groups of passive filters, have been used to compensate reactive power. The compensation amount of TIF can be adjusted with the variation of load power. However, the parallel and the series resonace could occur between TIF and grid impedance a STATCOM model is also developed. simulation studies are carried out in the digsilent/power factory to illustrate the performance of the new TCS and TCR connected wind power system.the results indicate that the new approach can not only enhance the low-voltage ride-through capability of wind turbines. The simulink results are simulated by using MATLAB/SIMULINK software.
