Abstract:	This paper presents a multi-functional thyristor-controlled LC (TCLC) compensator for enhancement of low voltage ride through (LVRT) capability of wind farms and active power flow management along with grid current harmonic mitigation. The proposed TCLC controller designed on generalized reactive power theory, enables the compensator to deliver reactive power in case of severe voltage dip during fault condition. It also controls the flow of active power under normal circumstance. In the presence of harmonics in the utility grid, the TCLC compensator can act as harmonic compensator. The compensator elements have been designed depending on the range of injected reactive power and harmonic current rejection analysis. Simulation results and comparative assessme nt establish the improved performance of the compensator over other state-of-the-art techniques for LVRT improvement. Results obtained from the real-time digital simulator (RTDS) prove the efficacy and reliability of the TCLC compensator. [ABSTRACT FROM AUTHOR]
