Raju, R.Shubhanga, K.N.2026-02-0620142014 IEEE International Conference on Power Electronics, Drives and Energy Systems, PEDES 2014, 2014, Vol., , p. -https://doi.org/10.1109/PEDES.2014.7041954https://idr.nitk.ac.in/handle/123456789/32562This paper presents the implementation of a phase locked loop (PLL) using Real-Time Application Interface (RTAI) on Linux platform. This PLL has been employed to generate firing pulses for gating the thyristors of a thyristor controlled series capacitor (TCSC) developed in the laboratory. The working of the TCSC in the capacitive vernier mode is depicted through a set of oscilloscope plots. A detailed waveform analysis is also carried out to show the harmonic performance of the TCSC. © 2014 IEEE.Phase locked loop (PLL)RTAI-LinuxThyristor controlled series capacitor (TCSC)
