Abstract

This paper proposes a novel comprehensive model of a vector-controlled induction motor drive in positive sequence transient stability simulation (PSTSS) programs. The model is implemented to approximate the behavior of the point-on-wave drive model, and applied to investigate the dynamic performance of the advanced drive loads in system-level simulations. This positive-sequence drive model is developed by reducing the three-phase electrical and control representations into d-q axes positive-sequence formulations. For the positive-sequence model, the line-side rectifier is interfaced to the grid through a voltage source with separate d-q axes controls to regulate the power factor of the drive. The machine-side inverter control system is represented based on rotor flux oriented control. The dc-link of the drive converter is implemented by employing the average model of the pulse-width modulated (PWM) converter, and is utilized to integrate the line-side rectifier and machine-side inverter. The proposed motor drive model is validated by comparing the performance with the electro-magnetic transient (EMT) point-on-wave drive model. The VAr support capability of the drive load and system-level simulation are investigated by incorporating the developed model into a composite load structure in PSTSS programs.
