Power Factor & Re-Active Power Control By D-SVC System

Abstract

The Stability of power factor and management of reactive power play a crucial role in support of the efficiency and reliability of contemporary industrial power systems. Poor management of reactive power in a high-voltage distribution system might result in conditions characterized by voltage instability, harmonic distortion, and energy inefficiency, particularly in the distribution system serving non-linear, rapidly varying loads, like Electric Arc Furnaces (EAFs). Such dynamic conditions are frequently not well served by conventional compensation techniques, such as capacitor banks and thyristor-based SVCs. This paper explores the use of a Dynamic Static VAR Compensator (DSVC) system in a 33 kV industrial distribution system to address areas of such difficulties. The DSVC was also simulated and tested in a realistic industrial operating environment, and its efficiency in converting power factor, Total Harmonic Distortion (THD), and power stability of the voltage were tested. Parameters of interest, such as reactive power flow, harmonic analysis based on FFT, and voltage flicker, were fitted with data. The findings indicated that the 5th harmonic of 2.3% was reduced to 0.4%, and there was an observable enhancement in the power factor. These results establish that DSVC is a quick, versatile, and dependable approach to reactive power control within complicated industrial setups.
