| Abstract | ||
| This research presents a harmonic analysis of the power system with static VAR compensator. The model is formed by parallel combination of Thyristor Control Reactor (TCR) with a bank of capacitor .This model based on use of harmonic switching functions and this harmonic model is completely general and can be interpreted as a harmonic admittance equivalent. It is suitable for direct incorporation into the harmonic domain frame of reference where it combines easily with frequency dependent admittances of the transmission network, and with other linearised component. This approach leads to efficient iterative solution of power networks containing TCR. The general operating condition corresponds to a case, when the switching instant of thyristor valve are function of network nodal voltage conditions, this applies to both thyristor turn-on and turn-off instants. In such situation the voltage zero crossing points calculated with good accuracy at each iterative step, are used to update the TCR switching function. Newton-Raphson technique is used to determine the zero-crossing points. | ||
