Study on intelligent dynamic reactive power compensation facility

An intelligent dynamic reactive power compensation facility is presented. Its working principles are detailed. The MOTOROLA single chip microcomputer is adopted as the core of the controller. Based on the reactive compensation theorem, an optimal control method for automatic capacitor compensation is set up. The software and hardware of the controller is designed. The thyristors are applied for the fast automatic contactless switching of capacitor sets. It detects the voltage across the SCR and takes zero voltage as its necessary condition of triggering. The hardware locking protection avoids the over compensation and the component damage by rush current from improper triggering. The reactive power compensation facility realizes the optimal, reliable and automatic operation and has excellent controllability and adaptability.
