Design and Implementation of Power System Performance Improvement by Using Pfc

Abstract

Electricity demands are increasing globally. Replacement is only feasible if done on a grander scale if economic and environmental considerations can be taken into account. The only other option is to fully use the current structure. Can run on the full potential of current technology while at a minimum risk to stability, protection, and efficiency With regard to control trait, the UPFC is the most flexible. With its current setup, UPFC is more expensive than the other controllers since it comprises of two VSCs. and UPFC cannot be retrofitted to the original equipment including shifted capacitor, and/rotating capacitor, etc. To make cost efficient and efficiency. This paper studies two possible topologies for HPFC, one with a central office and one without. On both topologies, the reactive power compensator and two virtual grounds, have two virtual switched capacitor blocks. the FACTS system includes two converters in series and one shunt Switched capacitor may be used in place of the shunt in HPFC to obtain a full conversion in the first topology, whereas in the second topology, two series converters are used in order to transform the input signal. In topology, one of the HPFC units is substituted by thyristor operated impedance and the other is made “½ the height. The scheme of this model's operational topology has the same topological features of the UPFC, but does not use any of the available converter MVAs.The simulations are simulated in MATLAB/Simulink UPFC can be contrasted with the HPFC to prove that it is both efficient and superior in terms of results
