TBSC-TCR Compensator Simulation: A New Approach in Closed Loop Reactive Power Compensation of Dynamic Loads
Topology for reactive power compensation of dynamic load in closed loop is presented. The scheme consists of Thyristor Binary Switched Capacitor (TBSC) banks and a Thyristor Controlled Reactor (TCR). TBSC is based on a chain of Thyristor Switched Capacitor (TSC) banks arranged in binary sequential manner. TCR capacity is chosen to be smallest of TBSC step size. A transient free switching of TBS...
متن کاملEmploying Grey System Model for Prediction of Electric Arc Furnace Reactive Power to Improve Compensator Performance
Electric arc furnaces (EAFs) are regarded as one of the major sources of voltage fluctuation in power systems which can contribute to a phenomenon known as flicker. One of the most convenient ways to mitigate flicker is employing static VAr compensators (SVCs). By employing prediction models to forecast EAF reactive power SVC performance can be improved very noticeably. In this paper a Grey sys...
متن کاملAn Innovative TCR Compensator for Closed Loop Reactive Power Compensation of Dynamic Loads
Topology for closed loop reactive power compensation suitable for dynamic loads using TCR is presented. Firing angle range of TCR is selected in such a way to keep the harmonic content at a minimum level. Simulation results show that the proposed scheme can achieve reactive power compensation in less than a half cycle and the harmonics contents of source are maintained at insignificant levels d...

متن کاملVariable VAR compensator circuits
A family of two reactive-power compensator circuit is presented. A general model of some basic linear elements and switching function blocks is developed first. Then the two proposed compensator circuits are derived from the generalised model. The proposed circuits are capable of supplying leading as well as lagging reactive currents in stepless variation without using an inverter configuration...
