Abstract
This paper proposes a novel comprehensive model of a rectifier-controlled induction motor drive for use in positive-sequence transient stability simulation (PSTSS) programs. The model is implemented to approximately capture 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 systematically developed by reducing the detailed three-phase electrical and control representations into dq axes positive-sequence formulations. For the positive-sequence model, the line-side rectifier is interfaced to the grid through a voltage source with separate dq axes controls to regulate the active and reactive power 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 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 electromagnetic transient point-on-wave drive model. The VAr support capability of the drive load model is investigated by incorporating the developed model into a composite load structure in PSTSS programs. Multiple units of the developed drive models are represented in large-scale transmission systems to examine the system-level responses of drive loads.
