Detailed modeling of static VAr compensators using the electromagnetic transients program (EMTP)

A detailed model of static VAr compensators (SVC) has been developed for digital simulation of electrical transients. The model is applicable to SVC configurations employing thyristor-switched capacitors (TSCs) and thyristor-controlled reactors (TCRs). A modeling technique based on electromagnetic transients program (EMTP) data modularization is used to represent essential parts of the SVC main circuit and control system. To verify the model, an actual SVC is simulated with the EMTP and the results are compared with the transient-network-analyzer-type simulator using actual SVC controls.>
