Abstract
Harmonics have become an important issue as the number of non-linear elements and electronic devices coupled to electrical power systems increases by the day. A Fixed Capacitor Thyristor Controlled Reactor (FC-TCR) is widely used in power systems to continuously control reactive power. This paper presents the harmonic analysis of a three-phase FC-TCR under different operating conditions using the Dynamic Harmonic Domain (DHD) technique. The existing Harmonic Domain (HD) method is widely used to obtain the steady-state harmonics in the power grid. It is not possible to calculate transient harmonics using the harmonic domain method. The dynamic harmonic domain technique also provides a solution for the transient condition. The three-phase FC-TCR is simulated in a MATLAB environment and calculates transient harmonic quantities such as apparent power S(t), reactive power Q(t), real power P(t), and distortion power D(t), RMS values, and distortion factors of the three-phase FC-TCR when subjected to voltage disturbance.
