Power quality optimization and reactive power control by modeling of SVC in healthcare centre

Abstract

Electric load of hospitals and medical centers draws reactive power from supply sources resulting in low power factor operating condition. Depending on the load type and patterns, various compensating strategies can be used to correct and counteract rapid variations. Voltage Sourced Static Synchronous VAR Compensators (SVC) doesn't depend on passive components for reactive power control since it uses electronic circuits to create lead or lag angles between applied voltage and injected current into the network to generate capacitive or absorbs inductive (Reactive Power). This practice became a state-of-art technology in reactive power control systems combining both, power and control engineering, to respond to dynamic system variations in milliseconds. The paper clearly address an existing problem of power quality and presents a model of distribution system in 480 bed hospital context using measured values explored through simulation. It uses SVC for voltage stabilizing and improving of power factor in general hospital with steady state condition.
