The device switching frequency of current-source converters (CSCs) in high-power medium-voltage (MV) drive applications is normally around 500 Hz. Conventional space vector modulation (SVM) features fast dynamic response but its output contains low-order harmonics with high magnitudes. Recently, a natural-sampling-based SVM (NS-SVM) with superior low-order harmonics performance has been proposed for...
This paper investigates feasibility of developing a predictive rating method to optimize line rating of underground transmission lines based on weather forecast information. Transmission lines, overhead or underground, are essential and indispensable parts of the electric grid which basically transfer energy from the production point to where it is needed. Line rating defined as line's maximum capacity...
Among various options available for wind energy conversion systems, this paper focuses on direct driven Synchronous Generator (SG) based variable speed wind turbine (VSWT). Generally SG is connected to the power grid via full-size power converters. But with the growing trend of multi mega watt turbine installation, the idea of modular- converter units is gaining popularity. Multi-module topology has...
