Abstract :
A procedure for simulating a static VAr system aimed at achieving optimal load compensation is presented. The paper details a new approach for reproducing the performance of digitally-controlled SVCs. The simulation is made using the EMTP (ElectroMagnetic Transients Program); the language MODELS is used for modelling the microprocessor-based control. The aim of the paper is to prove that the control strategy used in this paper is adequate for optimal load compensation and the EMTP is a suitable tool for simulating digitally-controlled systems. Test results illustrate how the control strategy can improve the power factor and balance line currents
