Transitory Control Algorithm of Reactive Current for LSC of BDFIG Based Fuzzy Controller

Abstract

The main aim of the paper is transitory mechanism process of the reactive current through the line-side converters of BDFIG based fuzzy controller. In individual process, the quality of voltage waveform on point of mutual connection would be intensely affected owing to responsive power alteration of load. The LSC could not work normally because of the PCC voltage is greater than voltage of DC-link. To mitigate this issues, various control schemes i.e., predictive direct voltage control and direct current control are generally established in machine_ adjacent converter to supply the reactive power. The line side converter could support in controlling the voltage at point of common coupling variations through providing or observing reactive current. This proposed paper examines load transient state and voltage of PCC is quickly joined to the stator PW. Formerly the LSC controllability throughout the voltage swell of PCC is studied when load is separated commencing the stator PW. In this paper a High HVRT control scheme with fuzzy controller is suggested through utilizing the LSC reactive current. The simulation results of proposed method is verified by MATLAB/SIMULINK environment.
