Design and Simulation of Double Loop Control for Power Converter Fed Variable Speed DC Drive

Variable speed pumped storage hydropower plants for integration of wind power in isolated power systems

Energy storage is a key issue when integrating large amounts of intermittent and nondispatchable renewable energy sources into electric power systems. To be able to maintain the instantaneous power balance and to compensate for the influence of power fluctuations that might result from renewable sources, flexible capability for power control is needed. Therefore, sufficient energy storage with ...

Modern Topology& Thermal Analysis of Drive for Variable Speed Pumped Storage Power Plant

Given the significant power generation and consumption of variable-speed pumped storage power plants (VSPSPs), it is crucial to enhance drive methods and decrease drive losses, thereby increasing productivity. This paper proposes the topology for VSPSP drivers with two level voltage source converters (2LVSC) with 6+1 converters. Hydraulic and electrical VSPSP models are presented, following whi...

Stator-Flux-Oriented Based Encoderless Direct Torque Control for Synchronous Reluctance Machines Using Sliding Mode Approach

In this paper a sliding-mode torque and flux control is designed for encoderless synchronous reluctance motor drive. The sliding-mode plus PI controllers are designed in the stator-flux field oriented reference frame which is able to track the mentioned reference signals with a minimum pulsations in the state condition. In addition, with these controllers a fast dynamic response is also achieve...
