Abstract

Transmission system expansion in India has not been consistent with the growth of demand in the states, resulting in suboptimal utilization of generation capacity. It is therefore critical to ensure that the existing transmission assets are fully utilized by loading them much closer to their capacity. One of the major concerns, then, is the secure operation of the system because of the presence of low-frequency electromechanical oscillations typically in the range of 0.1–0.8 Hz. One primary way of tackling the problem is to improve the dynamic behavior of the system and thereby allowing system operation closer to the capacity, without compromising security. In this paper, the authors have explained about low frequency oscillations and how it can be addressed using FACTS self tuning controllers.
