Description
Summary:Time domain stability simulation results using derived load models were compared with corresponding data obtained from transient disturbance recorders to validate the accuracy of the load models. Observations of real and reactive power load responses at primary substations and real and reactive power flows on major trunk lines indicated that using a composite (dynamic and static) load model provides a more accurate representation than other models, and closely matches the actual recorded values from the Taipower System. A severe fault, during which enormous voltage and frequency excursions occurred in the system, was extensively examined considering load rejection due to large voltage drops.< >
