Sensarma, PS and Padiyar, KR and Ramanarayanan, V (2001) Analysis and Performance Evaluation of a Distribution STATCOM for Compensating Voltage Fluctuations. In: IEEE Trans. on Power Delivery, 16 (2).
Controller design of a STATCOM-based voltage compensator requires a valid analytical model of the system. If phasor algebra is used for modelling, it is difficult to accurately describe the STATCOM behaviour during compensation of the sub-cycle transients in the PCC voltage. In this paper, a small signal model of the system, with a distribution line, is derived. Predictions based on frequency domain analysis are made, which are validated by experimental results. This model, therefore, can be used for controller design where sub-cycle voltage transients are to be compensated. It is shown that the voltage controller, so designed, can accomplish voltage sag mitigation. A discussion on the design of dc bus voltage controller - and experimental results showing its performance - is also included.
