This paper presents a new current source converter topology that is mainly intended for photovoltaic (PV) applications. The proposed system composed of a PV generator, an impedance adapter, DC-DC converter, a storage battery, multilevel current source Inverter CSI and a vector controlled induction machine. Our objectives here are focused on modeling, control, and steady-state and transient performances...
With a growing penetration of Permanent Magnet Synchronous Wind Turbine Generations (PMSG-WT) into the modern power system, a comprehensive modeling and analysis of PMSG-WT is required to investigate its dynamic stability and interaction between large wind farm and power grids. In this work, a complete detailed MW-class variable speed Wind Turbine System based on a Permanent Magnet Synchronous Generator...
The wind turbines used for power generation should enable to produce maximum power, making best use of available energy in the wind. A specific known terminology: Maximum Power Point Tracking (MPPT) must be introduced to obtain maximum energy efficiency. The strategy from this command is to control the electromagnetic torque to adjust the speed mechanics to maximize the electrical power generated...
The paper investigates the performance of variable speed wind turbine (VSWT) configuration with DC-DC converter under restricted output power conditions. The considered regimes of turbine operation are: at maximum available aerodynamic power and at limited output electric power. The wind turbine system consist of synchronous generator (SG) connected to diode rectifier, DC chopper and load. Two different...
