A Control Algorithm for Reactive Power Compensation of Ferroalloy Furnace Base on Spline Interpolation
The TCR (Thyristor-Controlled Reactor) model of SVC (Static Var Compensation) is designed reactive power compensation. It is mainly used to solving voltage fluctuation, flick and three phases unbalance and so on about network power quality problem. The problem is evocable by the impulse load of arc furnace and rolling mill. Arc furnace is characterized by low voltage, big current and nonlinear load. That determine reactive power becomes bigger comparably and efficiency factor is low too. In this paper take TCR and FC as reactive power compensation that is more and more popular now. Reactance current is controlled by charging trigger angle. The effect of reactive power compensation is influenced by calculate precision of trigger control angle. The spline interpolation function as a calculation method of thyristors trigger control angle is made use of in this paper. The method is verified that calculation volume low, applicability better and precision high by computer simulation.
