High performance AC–DC control power supply for low voltage ride through inverters
Sadhana, 2016This paper presents a control power supply (CPS) design which is used to feed power to the subsystems of a power converter. The CPS design presented here maintains a constant 24V dc output even over a wide (90V rms to 270V rms ) ac voltage variation ...

Improvement of High-Voltage-Ride-Through Capability of DFIG Based Wind Turbines with D-STATCOM
Applied Mechanics and Materials, 2013Along with the increasing of wind power penetration in the grid, much attention has been paid to the high voltage ride through (HVRT) capability of double fed induction generator (DFIG) based wind parks. To regulate the reactive power dynamically, the distribution static synchronous compensator (D-STATCOM) has been considered to be a valid method.

Low and high voltage ride-through of DFIG wind turbines using hybrid current controlled converters
Electric Power Systems Research, 2011Abstract Doubly fed induction generators have been recognized as the dominant technology used in wind generation systems. However, this type of wind generator is very sensitive to the drop/rise in the supply voltage and without efficient “ride-through” strategy, continuous operation of DFIG may fail due to destructive overcurrents in the rotor ...

Low voltage ride through control strategy for high-power grid-connected photovoltaic inverter
2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2013This paper presents a low voltage ride through (LVRT) control strategy for high-power grid-connected photovoltaic (PV) inverter, which can assure the PV inverter operates under grid faults with sinusoidal output currents. The control strategy of PV inverter is made up of inner current loops and outer voltage loop in a cascade structure under normal ...
