Simulation Based TSC-TCR Static VAR Compensator In Closed Loop Operation For Dynamic Reactive Load

In this paper proposed topology work deals with a firing angle range control and minimization of harmonics in thyristor controlled reactor (TCR) and transient free switching of thyristor switched capacitor (TSC). In recently Static VAR Compensators generally consists of a thyristor switched capacitor (TSC) and a thyristor controlled reactor (TCR) and compensates loads through generation or absorption of reactive power. The operation of thyristor controlled reactors at appropriate conduction angles can be used advantageously to meet the phase-wise unbalanced and varying load reactive power demand in a system. However, such as an operation deteriorates the quality of power supply through percolation of harmonic currents generated into the mains. This topology proposes how the delta connected TCR minimizes the harmonic components and transient free switching operation of TSC bank. Harmonics in the SVC can be minimizing by controlling the firing angle within the range of TCR. Also it provides almost step less variation of reactive power.
