A Practical Dynamic Phasor Model of Static VAR Compensator

This paper presents a three phase dynamic phasor model of static VAR compensator which takes fundamental and fifth harmonic into consideration. The modelling approach is based on the time-varying Fourier coefficient series of the power system variables. By truncating the less important higher order terms and keeping the significant ones, the new dynamic phasor model can realistically simulate the dynamic behaviour of SVC with fast speed and high accuracy. Without any simplified assumption, the new model is applicable to fast numerical simulation of SVC. Computer simulation results show the accuracy and efficiency of the dynamic phasor model of SVC.
