The present status of reactive power compensation technique in electric power industry is reviewed . Reactive power and harmonic will decrease power network quality and compensators with contact switch have some drawback , one new thyristor switching capacitor equipment for reactive power compensation are introduced ,the 80196KB 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 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 . Key words: var compensation; thyristor switched capacitor; zero-voltage switching; single-chip microcomputer 目 录 低压动态无功补偿装置的设计相关范文 |
