Design and Development of Static Voltage Stability Enhancer

Voltage instability in electrical distribution systems can cause power quality issues, equipment damage, and reduced efficiency. This work presents the design of a Static Voltage Stability Enhancer (SVSE) using the PIC18F252 for fast and accurate voltage regulation. The system continuously monitors input voltage, applies real-time control through power- electronic switching and transformer tap selection, and maintains stable output within safe limits. Experimental results demonstrate improved voltage stability, rapid response, and reliable performance, making the SVSE a compact and cost- effective solution for domestic, commercial, and small-scale industrial applications.
